I recently covered the Stadtbahn, a mode of rail transportation running as rapid transit (almost always a subway) in city center and as a tramway farther out. The tram-train is the opposite kind of system: it runs as a tramway within the city, but as rapid transit farther out. There’s a Human Transit blog post about this from 2009, describing how it works in Karlsruhe, which invented this kind of service pattern. Jarrett is bearish on the tram-train in most contexts, giving a list of required patterns that he says is uncommon elsewhere. It’s worth revising this question, because while the tram-train is not very useful in an American context, it is in countries with discontinuous built-up areas, including Germany and the Netherlands but also Israel. Israeli readers may be especially interested in how this technology fits the rail network away from the Tel Aviv region.
What is a tram-train?
Let’s dredge the 2*2 table from the Stadtbahn post:
|Slow in center||Fast in center|
|Slow in outlying areas||Tramway||Stadtbahn|
|Fast in outlying areas||Tram-train||Rapid transit|
The terms fast and slow are again relative to general traffic. The Paris Métro averages 25 km/h, less than some mixed-traffic buses in small cities, but it still counts as fast because the speed in destinations accessed per hour is very high.
Be aware that I am using the terms Stadtbahn and tram-train to denote two different things, but in Karlsruhe the system is locally called Stadtbahn. German cities use the term Stadtbahn to mean “a tramway that doesn’t suck,” much as American cities call a dazzling variety of distinct things light rail, including lines in all four cells of the above table. Nonetheless, in this post I am keeping my terminology distinct, using the advantage of switching between different languages and dialects.
Tram-trains and regional rail
The Karlsruhe model involves trains running on mainline track alongside mainline trains, diverging to dedicated tramway tracks in the city, to connect Karlsruhe Hauptbahnhof with city center around Marktplatz. This also includes lines that do not touch the mainline, like S2, but still run with higher-quality right-of-way separation outside city center; but most lines run on mainline rail part of the way.
North American light rail lines, with the exception of the Boston, Philadelphia, and San Francisco Stadtbahn systems, tend to run as tram-trains, but never have this regional rail tie-in. They run on entirely dedicated tracks, which has two important effects, both negative. First, it increases construction costs. And second, it means that the shape of the network is much more a skeletal tramway map than the more complicated combination of an S-Bahn and a tramway that one sees in Karlsruhe. San Diego has a short segment sharing tracks with freight with time separation, but the shape of the network isn’t any different from that of other American post-1970s light rail systems, and there’s an ongoing extension parallel to a mainline railroad that nonetheless constructs a new right-of-way.
In this sense, the Karlsruhe model can be likened to a cheaper S-Bahn. S-Bahn systems carve new right-of-way under city center to provide through-service whenever the historic city station is a terminus, such as in Frankfurt, Stuttgart, Munich, or German-inspired Philadelphia. They can also build new lines for more expansive service, higher capacity, or a better connection to city center, like the second S-Bahn trunk in Hamburg; Karlsruhe itself is building a combined road and rail tunnel, the Kombilösung, after a generation of at-grade operation. The tram-train is then a way to achieve some of the same desirable attributes but without spending money on a tunnel.
It follows that the tram-train is best when it can run on actual regional rail tracks, with good integration with the mainline system. It is a lower-speed, lower-cost version of a regional rail tunnel, whereas the North American version running on dedicated tracks is a lower-cost version of a subway. Note also that regional rail can be run at different scales, the shorter and higher-frequency end deserving the moniker S-Bahn; the Karlsruhe version is long-range, with S1 and S11 reaching 30 km south of city center and S5 reaching 70 km east.
Where is a tram-train appropriate?
Jarrett’s 2009 post lays down three criteria for when tram-trains work:
- The travel market must be small enough that an S-Bahn tunnel is not justified.
- The destination to be served isn’t right next to the rail mainline.
- The destination to be served away from the mainline is so dominant that it’s worthwhile running at tramway speeds just to get there and there aren’t too many people riding the line beyond it.
The center of Karlsruhe satisfies the second and third criteria. It is borderline for the first – the region has maybe a million people, depending on definitions, and the city proper has 312,000 people; the Kombilösung is only under-construction now and was not built generations ago, unlike S-Bahn tunnels in larger cities like Munich.
Jarrett points out that in the urban world he’s most familiar with, consisting of the United States, Canada, Australia, and New Zealand, it is not common for cities to satisfy these criteria. He does list exceptions, for example Long Beach, where the Blue Line runs in tramway mode before heading into Los Angeles on a mostly grade-separated right-of-way, whereupon it goes back into the surface in Downtown LA before heading into an under-construction tunnel. But overall, this is not common. City centers tend to be near the train station, and in the United States there’s such job sprawl that just serving one downtown destination is not good enough.
That said, the Long Beach example is instructive, because it is not the primary city in its region – Los Angeles is. I went over the issue of outlying S-Bahn tunnels a year ago, specifying some places where they are appropriate in Israel. The tram-train must be a key tool in the planner’s box as a cheaper, lower-capacity, lower-speed version of the same concept, diverging from the mainline in tramway mode in order to serve a secondary center. Karlsruhe itself is a primary urban center – the only time it’s the secondary node is when it connects to Mannheim, and that train doesn’t use the tramway tracks – but a secondary tram-train connection is being built in outlying areas there, namely Heilbronn.
Different models of urban geography
In the American model of urban geography, cities are contiguous blobs. Stare at, for example, Chicago – you’ll see an enormous blob of gray stretching in all directions. Parkland is mostly patches of green in between the gray, or sometimes wedges of green alternating with wedges of gray, the gray following commuter railroads and the green lying in between. Boundaries between municipalities look completely arbitrary on a satellite map.
In the German model of urban geography, it’s different. Look at Cologne, Frankfurt, Mannheim, or Stuttgart – the built-up area is surrounded by green, and then there are various suburban towns with parkland or farmland in between. This goes even beyond the greenbelt around London – there’s real effort at keeping all these municipalities distinct.
I don’t want to give the impression that the United States is the weird one. The contiguous model in the United States is also common in France – Ile-de-France is one contiguous built-up area. That’s how despite being clearly a smaller metropolitan region than London, Paris has the larger contiguous population – see here, WUP 2007, and see also how small the German and Dutch urban areas look on that table. Urban agglomeration in democratic East Asia is contiguous as in the US and France. Canada looks rather American to me too, especially Vancouver, the city both Jarrett and I are the most familiar with, while Toronto has a greenbelt.
This distinction moreover has to be viewed as a spectrum rather than as absolutes. Boston, for example, has some of the German model in it – there’s continuous urbanization with inner suburbs like Cambridge and Newton, but beyond Route 128, there are many small secondary cities with low density between them and the primary center. Conversely, Berlin is mostly American or French; the few suburbs it has outside city limits are mostly contiguous with the city’s built-up area, with the major exception of Potsdam.
The relevance of this distinction is that in the German or Dutch model of urban geography, it’s likely that a railway will pass through a small city rather far from its center, fulfilling the second criterion in Jarrett’s post. Moreover, this model of independent podlike cities means that there is likely to be a significant core, which fulfills the third criterion. The first criterion is fulfilled whenever this is not the center of a large metropolitan area.
It’s not surprising, then, that the Karlsruhe model has spread to the Netherlands. This is not a matter of similarity in transport models: the Netherlands differs from the German-speaking world, for examples it does not have monocentric S-Bahns or S-Bahn tunnels and it builds train stations with bike parking where Germany lets people bring bikes on trains. Nonetheless, the shared model of distinct municipalities makes tram-train technology attractive in South Holland.
Israel and tram-trains
In Israel, there are very few historic railways. A large share of construction is new, and therefore has to either swerve around cities or tunnel to enter them, or in a handful of cases run on elevated alignments. Israel Railways and local NIMBYs have generally preferred swerving.
Moreover, the urban layout in Israel is very podlike. There do exist contiguous areas of adjacent cities; Tel Aviv in particular forms a single blob of gray with Ramat Gan, Givatayim, Bni Brak, Petah Tikva, Bat Yam, and Holon, with a total population of 1.5 million. But for the most part, adjacent cities are buffered with undeveloped areas, and the cities jealously fight to stay this way despite extensive developer pressure.
The final important piece in Israel’s situation is that despite considerable population growth, there is very little rail-adjacent transit-oriented development. The railway was an afterthought until the Ayalon Railway opened in 1993, and even then it took until last decade for mainline rail to be a significant regional mode of transport. The state aggressively builds new pod-towns without any attempt to expand existing towns toward the railway.
The upshot is that all three of Jarrett’s criteria for tram-trains are satisfied in Israel, everywhere except in and around Tel Aviv. Tel Aviv is large enough for a fully grade-separated route, i.e. the already-existing Ayalon Railway. Moreover, because Tel Aviv needs full-size trains, anything that is planned to run through to Tel Aviv, even as far as Netanya and Ashdod, has to be rapid transit, using short tunnels and els to reach city centers where needed. A tram-train through Ashdod may look like a prudent investment, but if the result is that it feeds a 45 meter long light rail vehicle through the Ayalon Railway then it’s a waste of precious capacity.
But Outside Tel Aviv, the case for tram-trains is strong. One of my mutuals on Twitter brings up the Beer Sheva region as an example. The mainline going north has a station called Lehavim-Rahat, vaguely tangent to Lehavim, a ways away from Rahat. It could get two tramway branches, one diverging to the built-up area of Lehavim, a small suburb that is one of Israel’s richest municipalities, and the other to Rahat, one of Israel’s poorest. There are also interesting options of divergence going south and east, but they suffer from being so far from the mainline the network would look scarcely different from an ordinary tramway.
Beer Sheva itself would benefit from tramways with train through-service as well. The commercial center of the city is close to the train station, but the university and the hospital aren’t, and are not even that close to the subsidiary Beer Sheva North station. The station is also awkwardly off-center, lying southeast of the city’s geographic center, which means that feeding buses into it with timed transfers screws internal connections. So tramway tracks on Rager Boulevard, cutting off Beer Sheva North for regional trains, would do a lot to improve regional connectivity in Beer Sheva; intercity trains should naturally keep using the existing line.
In the North, there are similar examples. Haifa is not going to need the capacity of full-size trains anytime soon, which makes the case for various branches diverging into smaller cities to provide closer service in tramway mode strong. Unlike in Beer Sheva, the case for doing so in the primary center is weak. Haifa’s topography is the stuff of nightmares, up a steep hill with switchback streets. The mainline already serves the Lower City well, and climbing the hill is not possible.
This creates an interesting situation, in which the technology of the tram-train in the North can be used to serve secondary cities like Kiryat Ata and Tirat Carmel and maybe enter the Old City of Acre, but the operational pattern is really that of a Stadtbahn – fast through Haifa and up most of the Krayot, slow through smaller suburbs.
I made an off-hand remark about subway-surface systems, called Stadtbahn in German (as is, confusingly, the fully grade-separated east-west Berlin S-Bahn line), regarding a small three-line single-tail network that Brooklyn could build. I also talked about it in a little more detail last year. I want to go more deeply into this now. It’s a public transportation typology that’s almost nonexistent outside Germany and Belgium; Tel Aviv is building one line, and the US has three but two of those are from more than 100 years ago. But there are interesting examples of good places to use this technology elsewhere, especially elsewhere in Europe.
What is the Stadtbahn?
The Stadtbahn (“city rail”), or the subway-surface line in US usage, is an urban line running light rail vehicles, with grade separation in city center and street running outside city center. All examples I know of are in fact underground in city center, but elevated lines or lines running in private rights-of-way could qualify too, and in Cologne, there’s a semi-example over a bridge dropping to the surface at both ends.
It’s best illustrated as a 2*2 grid:
|Slow in center||Fast in center|
|Slow in outlying areas||Tramway||Stadtbahn|
|Fast in outlying areas||Tram-train||Rapid transit|
The terms fast and slow are relative to general traffic, so a mixed-traffic bus in a low-density city that averages 30 km/h is slow whereas the Paris Métro, which averages 25 km/h, is fast; the speed in km/h may be higher on the bus, but the speed in destinations accessed per hour is incomparably higher on the Métro.
The tram-train is confusingly also called Stadtbahn in Germany, for example in Karlsruhe; this is nearly every light rail built in North America. It is not the topic of this post.
What is the purpose of the Stadtbahn?
Historically, Stadtbahn systems evolved out of pure surface tramways. City center congestion made the streetcars too slow, so transit agencies put the most congested segments underground. This goes back to Boston in 1897 with the Tremont Street Subway and Philadelphia in 1906 with the Subway-Surface Lines. The contrast both in that era and in the era of Stadtbahn construction in Germany from the 1960s to the 80s is with pure subways, which are faster but cost more because the entire route must be underground.
Stadtbahns always employ surface branching. This is for two reasons. First, there’s more capacity underground than on the surface, so the higher-capacity rapid transit segment branches to multiple lower-capacity tramways to permit high throughput. And second, there’s generally less demand on the outer segments than in the center – lines with very strong demand all the way tend to turn into full subways.
This is therefore especially useful for cities that are not huge. In a city the size of Cologne or Stuttgart or Hanover, there isn’t and will never be demand for a rapid transit system with good citywide coverage. Instead, there is something like a sector principle. For example, in Cologne, the Deutz side of the city, on the right bank of the Rhine, has service to city center on the S-Bahn, on tramway lines over the Deutzer Bridge branching on the surface, and on tramway lines over the Mülheimer and Severin Bridges feeding into the north-south ring Stadtbahn. Smaller cities have simpler systems – Hanover for has three underground trunk lines meeting at one central station, and Dortmund has three meeting in a Soviet triangle. This maintains good coverage even without the budget for many rapid transit lines.
Where are Stadtbahns appropriate?
Cities should consider this technology in the following cases:
- The city should not be too big. Tel Aviv is too big for this, and people in Israel are starting to recognize this fact and, in addition to the under-construction three-line Stadtbahn system are proposing a larger-scale three-line fully grade-separated metro system. If the city is big enough, then a full metro system is justified.
- There should be a definitive city center for substantial traffic to funnel to. The purpose of the Stadtbahn is to have comparable throughput to that of a metro, albeit with shorter trains.
- There should be wide swaths of sectors of the city where having multiple parallel lines is valuable. This, for example, is the case in cities that are not exceptionally dense and cannot expect transit-oriented development to completely saturate one metro corridor.
- The street network should not be too gridded, because then the sector-based branching is more awkward, and the combination of rapid transit to city center and a surface transit grid can be powerful, as in Toronto.
- There should be too much city center congestion for a pure surface system to work, for example if most streets are very narrow and traffic funnels to the few streets that can use
These circumstances are all common to German urbanism: city centers here are strong, but residential density peaks at 15,000/km^2 or thereabouts in near-center neighborhoods and drops to 3,000-6,000/km^2 farther out. Moreover, Germany lacks huge cities, and of the largest four urban cores – Berlin, Hamburg, Munich, Frankfurt – three have full rapid transit systems. Finally, grids are absent here except at very small scale, as in Mannheim.
However, these are not unique features to Germany. They’re common around Europe. European cities are not very big, and the only ones that can genuinely fill any subway line with transit-oriented development are a handful of very big, very rich ones like London and Paris. Even Stockholm and Munich have to be parsimonious; they have have full metro systems with branching.
The French way of building rapid transit does not employ the Stadtbahn, and perhaps it should. In a city the size of Bordeaux or Nice, putting a tramway underground in city center and then constructing new branches to expand access would improve coverage a lot.
This is likely also the case in Italian cities below the size class of Milan or Rome. Many of these cities are centered around Renaissance cores with very narrow streets, which are nonetheless auto-centric with impossibly narrow sidewalks, Italy having nearly the highest car ownership in Europe. Finding one to three good corridors for a subway and then constructing tramways funneling into them would do a lot to speed up public transit in those cities. Bologna, for example, is planning a pure surface tramway, but grade-separated construction in the historic center would permit trams to have decent coverage there without having to slow down to walking speed.
Are there good examples outside Europe?
Yes! From my original post from 2016, here is one proposal for New York:
The B41 could be a tramway going between City Hall and Kings Plaza, using two dedicated lanes of the Brooklyn Bridge. In that case, the line would effectively act as subway-surface, or more accurately elevated-surface: a surface segment in Brooklyn, a grade-separated segment between Manhattan and Brooklyn. Subway-surface lines should branch, as all current examples do (e.g. Boston Green Line, Muni Metro, Frankfurt U-Bahn), because the subway component has much higher capacity than the surface components. This suggests one or two additional routes in Brooklyn, which do not have strong buses, but may turn into strong tramways because of the fast connection across the river to Manhattan. The first is toward Red Hook, which is not served by the subway and cut off from the rest of the city by the Gowanus Expressway. Unfortunately, there is no really strong corridor for it – the streets are not very wide, and the best for intermediate ridership in Cobble Hill and Carroll Gardens require additional twists to get into the core of Red Hook. Court Street might be the best compromise, but is annoyingly a block away from the F/G trains, almost but not quite meeting for a transfer. The second possible route is along Flushing Avenue toward the Navy Yard; it’s not a strong bus by itself, but the possibility of direct service to Manhattan, if a Flatbush tramway preexists, may justify it.
Note that this proposal is opportunistic: Brooklyn Bridge just happens to be there and point in the right direction for at least one strong surface route in Brooklyn, and conversely would connect too awkwardly to the subway. In a city the size of New York, Stadtbahn lines must be opportunistic – if the region intentionally builds new river crossings then they must carry the highest-capacity mode of transportation, which is rapid transit, not a light rail variant.
American cities smaller than New York are often very big by European standards, but also very decentralized. This hurts the Stadtbahn as a mode – it really only works for a monocentric city, because if there are multiple centers, then all but the primary one get slow transit. The Rhine-Ruhr notably uses the S-Bahn, which is rapid transit, to connect its various cities, and only run Stadtbahn service internally to each center, like Cologne or Dortmund.
There are a number of places in the United States where burying a light rail line in city center is advisable, but this is for the most part conversion of a tram-train to rapid transit, for examples in Portland and Dallas. The only example that come to mind of a decent Stadtbahn in the US that doesn’t already exist is Pittsburgh, converting the BRT system to rail.
Outside the United States, I get less certain. Canada is bad geography for a Stadtbahn because of its use of grid networks; Ottawa may be good for a Stadtbahn using the Confederation Line tunnel, but that’s probably it. Australia may be better, combining decently strong city centers with very low residential density; transit-oriented development potential there is very high, but it could plausibly come around multiple distinct corridors as well as regional rail stations. Melbourne’s tramways thus may be a candidate for Stadtbahn conversion.
In both East Asia and in the developing world, it’s likely best to just build full metros. East Asian cities are big and have high rates of housing construction (except Hong Kong). I can see a Stadtbahn succeed in Taichung, extending the under-construction Green Line on the surface and building intersecting lines, but that’s probably it. Kaohsiung already has a (very underused) subway, what I think is Daejeon’s best next corridor on top of Line 1 and the planned Line 2 is unusually bad for a Stadtbahn because the streets are too gridded west of the center, Daegu is too gridded as well.
A similar set of drawbacks is also true for the developing world. The urban population of the developing world tends to cluster in huge cities. Moreover, these cities tend to have high residential density but low city center job concentration; the Addis Ababa light rail is bad at serving people’s work trips because so few people work in the center. Finally, the developing world has high rates of increase in urbanization, which make future-proofing systems with higher capacity more valuable.
What does leisure travel look like in a world where driving and flying are prohibitively expensive, and rail travel is more abundant and convenient?
It does not look exactly like today’s travel patterns except by train. Where people choose to travel is influenced by cultural expectations that are themselves influenced by available technology, prices, and marketing. Companies and outfits providing transportation also market the destinations for it, whether it’s a private railway selling real estate in the suburbs on its commuter lines, an airline advertising the resort cities it flies to, or a highway authority promoting leisure drives and auto-oriented development. The transition may annoy people who have gotten used to a set of destinations that are not reachable by sustainable transportation, but as the tourism economy reorients itself to be greener, new forms of leisure travel can replace old ones.
Historic and current examples
Railroads were the first mode of mechanized transportation, and heavily marketed the destinations one could reach by riding them. The involvement of some railroads in suburban development, such as Japanese private railroads or the original Metropolitan Railway, is fairly well-known to the rail advocacy community. Lesser-known but equally important is rail-based tourism. Banff and Jasper owe their existence to transcontinental railways, Lake Louise was founded as a montane resort on top of the Canadian Pacific Railway, Glacier National Park opened thanks to its location next to the (American) Great Northern. Even Niagara Falls, for all its unique natural beauty, benefited from heavy marketing by the New York Central, which offered the fastest route there from New York.
Other than Niagara Falls, the North American examples of rail-based tourism are all in remote areas, where people no longer travel by train. Some may drive, but most fly over them. The American system of national parks, supplemented by some state parks like the Adirondacks and Catskills, has thus reoriented itself around long-distance leisure travel by car. This includes popular spots like Yellowstone, Bryce, Grand Canyon, and Yosemite in the United States, Schwarzwald in Germany, or the tradition of summer homes in outlying areas in Sweden or the American East Coast.
The airline industry has changed travel patterns in its own way. Planes are fast, and require no linear infrastructure, so they are especially suited for getting to places that are not easy to reach by ground transportation. Mass air travel has created a tourism boom in Hawaii, the Maldives, southern Spain, the Caribbean, any number of Alpine ski resorts, Bali, all of Thailand. Much of this involves direct marketing by the airlines telling people in cold countries that they could enjoy the Mediterranean or Indian Ocean sun. Even the peak season of travel shifted – English vacation travel to the Riviera goes back to the early Industrial Revolution, but when it was by rail and ferry the peak season was winter, whereas it has more recently shifted to the summer.
The politics of vacation travel
In some cases, states and other political actors may promote particular vacation sites with an agenda in mind. Nationalists enjoy promoting national unity through getting people to visit all corners of the country, and if this helps create a homogeneous commercial national culture, then all the better. This was part of the intention of the Nazi program for Autobahn construction and Volkswagen sales, but it’s also very common in democratic states that aim to use highways for nation-building, like midcentury America.
If there’s disputed land, then nationalists may promote vacation travel there in order to instill patriotic feelings toward it among the population. Israel has turned some demolished Arab villages into national forests, and promoted tourism to marginal parts of the country; settler forces are likewise promoting vacation travel to the settlements, cognizant of the fact that the median Israeli doesn’t have strong feelings toward the land in the Territories and wouldn’t mind handing them over in exchange for a peace agreement.
Politics may also dictate promoting certain historic sites, if they are prominent in the national narrative. In the Jewish community, two such trips are prominent, in opposite directions: the first is the organized Israeli high school trips to Poland to see the extermination camps and the ghettos, perpetuating the memory of the Holocaust in the public; the second is Birthright trips for Jews from elsewhere to visit Israel and perhaps find it charming enough to develop Zionist feelings toward it.
So what does this mean?
I bring up the politics and economic history of leisure travel, because a conscious reorientation of vacation travel around a green political agenda is not so different from what’s happened in the last few generations. The big change is that the green agenda starts from how people should travel and works out potential destinations and travel patterns from there, whereas nationalist agendas start from where people should travel and are not as commonly integrated with economic changes in how people can travel.
The point, then, is to figure out what kinds of vacation travel are available by train. Let’s say the map that I put forth in this post is actually built, and in contrast, taxes on jet fuel as well as petrol rise by multiple euros per liter in order to effect a rapid green transition. Where can people go on vacation and where can’t they?
Intercity leisure travel
By far the easiest category of leisure travel to maintain in a decarbonized world is between cities within reasonable high-speed rail range. Tens of millions of people already visit Paris and London every year, for business as well as for tourism. This can continue and intensify, especially if the green transition also includes building more housing in big high-income cities, creating more room for hotels.
High-speed rail lives on thick markets, the opposite of air travel. Once the basic infrastructure is there, scaling it up to very high passenger volumes on a corridor is not difficult; the Shinkansen’s capacity is not much less than 20,000 passengers per hour in each direction. Many people wish to travel to Paris for various reasons, so the TGV makes such travel easier, and thus even more people travel to and from the capital. A bigger and more efficient high-speed rail network permits more such trips, even on corridors that are currently underfull, like the LGV Est network going toward much of Germany or the LGV Sud-Europe Atlantique network eventually connecting to much of Spain.
Germany does not have a Paris, but it does have several sizable cities with tourist attractions. A tightly integrated German high-speed rail network permits many people in Germany and surrounding countries to visit the museums of Berlin, go to Carnival in Cologne, attend Oktoberfest in Munich, see the architecture of Hamburg, or do whatever it is people do in Frankfurt. The international connections likewise stand to facilitate German travel to neighboring countries and their urban attractions: Paris, Amsterdam, Basel, Vienna, Prague.
Intercity travel and smaller cities
Big cities are the most obvious centers of modern rail-based tourism. What else is there? For one, small cities and towns that one encounters on the way on corridors designed to connect the biggest cities. Would Erfurt justify a high-speed line on its own? No. But it has an ICE line, built at great expense, so now it is a plausible place for travel within Germany. The same can be said about cities that are not on any plausible line but could easily connect to one via a regional rail transfer. When I fished for suggestions on Twitter I got a combination of cities on top of a fast rail link to Berlin, like Leipzig and Nuremberg, and ones that would require transferring, like Münster and Heidelberg.
Even auto-oriented vacation sites can have specific portions that are rail-accessible, if they happen to lie near or between large cities. In North America the best example is Niagara Falls, conveniently located on the most plausible high-speed rail route between New York and Toronto. In Germany, South Baden is normally auto-oriented, but Freiburg is big enough to have intercity rail, and as investment in the railroad increases, it will be easier for people from Frankfurt, Munich, and the Rhine-Ruhr to visit.
Farther south, some Swiss ski resorts have decent enough rail connections that people could get there without too much inconvenience. If the German high-speed rail network expands with fast connections to Basel (as is planned) and Zurich (which is nowhere on the horizon), and Switzerland keeps building more tunnels to feed the Gotthard Base Tunnel (which is in the Rail 2035 plan but with low average speed), then people from much of central and southern Germany could visit select Swiss ski resorts in a handful of hours.
The green transition as I think most people understand it in the 21st century is an intensely urban affair. Berlin offers a comfortable living without a car, and as the German electric grid replaces coal with renewables (slower than it should, but still) it slowly offers lower-carbon electricity, even if it is far from Scandinavia or France. Small towns in contrast have close to 100% car ownership, the exceptions being people too poor to own a car. But the world isn’t 100% urban, and even very developed countries aren’t. So what about travel outside cities large and small?
The answer to that question is that it depends on what cities and what railroads happen to be nearby. This is to a large extent also true of ordinary economic development even today – a farming town 20 km from a big city soon turns into a booming commuter town, by rail or by highway. Popular forests, trails, mountains, and rivers are often accessible by railroad, depending on local conditions. For example, some of the Schwarzwald valleys are equipped with regional railways connecting to Freiburg.
Here, it may be easier to give New York examples than Berlin ones. Metro-North runs along the banks of the Hudson, allowing riders to see the Palisades on the other side. The vast majority of travelers on the Hudson Line do not care about the views, but rather ride the train to commute from their suburbs to Manhattan. But the line is still useful for leisure trips, and some people do take it up on weekends, for example to Poughkeepsie. The Appalachian Trail intersects Metro-North as well, though not many people take the train there. Mountains are obstacles for rail construction, but rivers are the opposite, many attracting railroads near their banks, such as the Hudson and the Rhine.
Conversely, while New York supplies the example of the Hudson Line, Germany supplies an urban geography that facilitates leisure travel by rail out of the city, in that it has a clear delineation between city and country, with undeveloped gaps between cities and their suburbs. While this isn’t great for urban rail usage, this can work well for leisure rail usage, because these gaps can be developed as parkland.
Where’s the catch?
Trains are great, but they travel at 300-360 km/h at most. An aggressive program of investment could get European trains to average around 200-240 km/h including stops and slow zones. This allows fast travel at the scale of a big European country or even that of two big European countries, but does not allow as much diversity of climate zones and biomes as planes do.
This does not mean trains offer monotonous urban travel. Far from it – there’s real difference in culture, climate, topography, and architecture within the German-speaking world alone, Basel and Cologne looking completely different from each other even as both are very pretty. But it does limit people to a smaller tranche of the world, or even Europe, than planes do. A Berliner who travels by train alone can reach Italy, but even with a Europe-scale high-speed rail program, it’s somewhat less than 4:45 to Venice, 5:00 to Milan, 5:30 to Florence, 6:45 to Rome, 7:45 to Naples. It’s viable for a long vacation but not as conveniently as today by plane with airfare set at a level designed to redraw coastlines. Even in Italy, there’s great access to interesting historic cities, but less so to coastal resorts designed around universal car use, located in topographies where rail is too difficult.
The situation of Spanish resorts is especially dicey. There isn’t enough traffic from within Spain to sustain them, there are so many. Germany is too far and so is Britain if planes are not available at today’s scale. What’s more, people who are willing to travel 7 or 8 hours to a Spanish resort can equally travel 5 hours to a French or Italian one. The French Riviera has gotten expensive, so tourism there from Northern Europe feels higher-income to me than tourism to Alicante, but if people must travel by train, then Nice is 4:30 from Paris and Alicante is 7:30, and the same trip time difference persists for travelers from Britain and Germany.
Is it feasible?
High carbon taxes are not just economically feasible and desirable, but also politically feasible in the context of Europe. The jet fuel tax the EU is discussing as part of the Green Deal program is noticeable but not enough to kill airlines – but what environmental policy is not doing, the corona virus crisis might. If low-cost air travel collapses, then much of the market for leisure travel specifically will have to reorient itself around other modes. If Europe decides to get more serious about fighting car pollution, perhaps noticing how much more breathable the air in Paris or Northern Italy is now than when people drive, then taxes and regulations reducing mass motorization become plausible too.
The transition may look weird – people whose dream vacation involved a long drive all over Italy or France or Germany may find that said vacation is out of their reach. That is fine. Other vacations become more plausible with better rail service, especially if they’re in big cities, but also if they involve any of a large number of natural or small-town destinations that happen to be on or near a big city-focused intercity rail network.
Israel’s incoming prime minister Benny Gantz unveiled an emergency government, to take power following an upcoming confidence vote in the Knesset. The last two MKs required to give Gantz a 61-59 majority, two members of Gantz’s own Blue and White Party who were previously resolute not to go into coalition supported by the mostly Arab Joint List, relented after Gantz’s controversial attempt to enter a Netanyahu-led emergency unity government stalled due to disagreements over both security and coronavirus policy. Moreover, following revelations of government failures discovered last week by senior B&W MK Ofer Shelah, the new government announced sharp changes in policy toward both the Covid-19 emergency and broader domestic and foreign policy questions.
Of note, a major reshuffle in the state budget is expected. Some details are forthcoming, but short- and long-term reductions in settlement subsidies are expected. Moreover, reductions in subsidies to yeshiva students have been announced, delayed by a year due to the magnitude of the crisis within the Haredi community, which has 10% of Israel’s population but about half of Covid-19 hospitalization cases. Finally, a review of military procurement will be done due to the influence of the indicted Netanyahu on the process, but analysts expect that with so many former generals in the new government, including former IDF chief of staff Gantz himself, few real cuts to the IDF are forthcoming.
In lieu of these cuts, the new government is announcing a massive infrastructure investment program, funded partly by deficit spending to limit unemployment. Incoming health minister Ahmad Tibi of the Joint List, a medical doctor by training, promised that budget increases will invest in hospital capacity and hygiene, raise the wages of staff from doctors down to cleaning staff, and buy personal protective equipment (PPE) in sufficient quantities for universal mask-wearing. Outside health, energy and transportation are both on the list of budgetary winners. In energy, the collapse of the consortium of Yitzhak Tshuva and Noble Energy managing Israel’s natural gas reserves and the falling prices of solar power mean the state will invest in thermal solar power plants in the desert. In transportation, an infrastructure plan will invest in additional urban public transit capacity.
The situation of transportation is particularly instructive, because of the political element involved. Throughout most of the past 11 years of Netanyahu’s coalitions, the transport minister was the same politician, Yisrael Katz of Netanyahu’s Likud; Katz prioritized highway investments with some rail, and was viewed as the least controversial of Likud’s heavyweight politicians, many of whom find themselves embroiled in scandal following last month’s election. Nonetheless, to signify a break with the past, the new government is giving the transportation portfolio to Nitzan Horowitz, leader of the leftist Meretz party who has called for expansion of public transportation.
While car ownership in Israel is low, this is the result of car taxes and high poverty rates. Activists at Meretz, B&W, and the right-wing secular Yisrael Beitenu party all pointed out to religious laws banning public transportation and other services from running on Saturdays, promising to repeal them within months. Meretz activists as well as independent analysts expect everyday public transportation to encourage people to give up driving and rely on buses and trains more even on weekdays, requiring additional investment to cope with capacity.
Another political element identified by sources within B&W who spoke anonymously is that residents of Tel Aviv and most of its inner suburbs have long felt stiffed by state infrastructure plans; last decade, Mayor Ron Huldai clashed with Katz, demanding a subway in dense, upper middle-class North Tel Aviv. Meretz is especially strong in North Tel Aviv. However, Horowitz said that his priority was socioeconomic equality, and while he did favor subway expansion in and around Tel Aviv and would accelerate construction of the Green Line through North Tel Aviv, the budget would boost rail construction in working-class southern and eastern suburbs.
Several MKs at the Joint List added that there would also be additional funding for connections to the centers of Arab cities. One plan calls for a tunnel through Nazareth, Israel’s largest Arab-majority city, which would connect it with Tel Aviv and other larger Jewish cities while also functioning as a regional rail link for the majority-Arab Galilee region. Towns too small to justify a direct rail link would get a bus to the nearest train station on the same fare system with a timed connection. One Meretz member explained, “in unbroken countries of similar size to ours, like Switzerland and the Netherlands, bus and train planning is coordinated nationally and there is no conception that buses are for poor people and trains for rich people.” Members of both Meretz and the Joint List added that there had long been underinvestment in Arab areas, calling past policies racist and vowing to correct them.
Sources at B&W stressed that there’s short and long term. In the short term, the priority will remain the coronavirus crisis, and the state will go into a large deficit in order to invest in health care and limit the death toll. Additional spending on other infrastructure will focus on planning, so that the state can begin construction after the crisis is long over, and will be funded by reducing yeshiva funding; B&W and Yisrael Beitenu plans to also reduce child credits, as Haredi families are larger than secular ones, have stalled due to opposition by the Joint List, as Arab families are poor and larger than secular Jewish ones too.
While Gantz himself stressed the pragmatic aspects of the plan, sources close to him mentioned the spirit of the 1990s. Negotiations with the Palestinians will resume shortly, they promised, and a two-state compromise will be worked out. They further promise that the peace dividend will allow Israel to grow through closer trade ties with the Arab world and reduced ongoing security spending. But other sources within the new coalition are more skeptical, pointing out Gantz and Yisrael Beitenu leader Avigdor Lieberman’s trenchant opposition to dismantling most settlements as a red line that may scuttle future negotiations.
Nonetheless, all sources agree that a clear change in foreign and domestic policy is coming. The more skeptical sources say that the end result will be a shift in domestic spending building a more expansive urban rail network and higher-quality health care. But the more idealistic ones are saying that a new Middle East is coming, one in which a thriving Israel will be at the center, with world-class public infrastructure and private entrepreneurship.
There’s a thread on Twitter by Stephen Smith bringing up Zurich’s S-Bahn as an alternative to extensive metro tunneling. It reminded me of something I’d been meaning to write about for a long time, about how S-Bahn tunnels, in Zurich and elsewhere, include not just the bare minimum for through-running but also strategic tunneling elsewhere to reach various destinations not on the mainline. Zurich’s S-Bahn includes about 19 km of tunnel built since the 1960s, which is similar per capita to the amount of tunneling built for the Washington Metro.
Such tunneling is important to ensure a regional rail network reaches destinations off the mainlines. Even cities with metro systems need to understand this as long as they have some mainline rail serving suburban destinations. For example, in the Center of Israel, Tel Aviv is getting a subway-surface light rail network, but outside the urban core rail transport will remain dominated by Israel Railways service; as Israel Railways avoids many city centers, such as Netanya, short strategic tunnels are critical.
Tunnels in Zurich
The core of the Zurich S-Bahn is three city center tunnels: the 2 km Käferberg Tunnel from Oerlikon to Hardbrücke, the 7 km combination of the Hirschengraben Tunnel and the Zürichberg Tunnel from Hauptbahnhof to the Right Bank of Lake Zurich and points northeast, and the 5 km Weinberg Tunnel from Hauptbahnhof to Oerlikon and points north. The Käferberg Tunnel is from the 1960s, the Hirschengraben and Zürichberg Tunnel opened in 1989-1990 as the core of the Zurich S-Bahn, and the Weinberg Tunnel opened in 2014 as a second S-Bahn route to add more capacity.
These 14 km of tunnel look like any standard picture of regional rail tunneling. However, Zurich has in addition built a 5 km tunnel for a loop to the airport. Without this tunnel, no regional or intercity rail service to the airport would have been possible, as the airport was at a distance from the mainline; only trams could have served the airport then.
In addition to these 19 km, there is some talk of building an additional tunnel of 7-10 km on the Zurich-Winterthur Line, called the Brüttener Tunnel, to speed up service between these two cities.
Tunnels on other regional rail systems
In Paris, the RER consists not just of legacy rail track and city center tunnels, but also outlying tunnels reaching new destinations. The RER B connection to Charles de Gaulle Airport is new construction, opening in 1976 as a commuter line just before the RER opened and incorporated it as a branch. It’s a mix of above- and underground construction, totaling 5.5 km of tunnel. Two more key RER lines, at both ends of the RER A, are new: the branch to Cergy, which opened between 1979 and 1994 and has 3 km of tunnel, and the branch to Marne-la-Vallée, which opened in stages starting on the same day as the RER A’s central tunnel and continuing until reaching its terminus in 1992.
All three new RER branches are busy. They have to be – if there weren’t so much demand for them, it would have been financially infeasible to build them and those areas would have had to make do with a bus connection to the existing mainlines. The Marne-la-Vallée branch carries about two thirds of the eastern branch ridership of the RER A, making it most likely the busiest single rail branch in Europe.
In London, the regional rail network is less modern than in Paris, Zurich, and other cities with extensive development of new tunnels. Nonetheless, the Crossrail plans do include a short outlying tunnel reaching Heathrow Airport. Moreover, one of the two eastern branches of the mainline has the characteristics of an outlying tunnel, namely the branch to Canary Wharf. Canary Wharf is only 5 km from the City of London and the tunnel connecting to it is contiguous with the central tunnel, but the branch is not really about improving connections to onward suburbs. Where La Défense was always on the way to western suburbs on the RER, Canary Wharf is only on the way to Abbey Wood. There are proposals among area railfans to extend this branch much farther to the east, but no official plans that I know of. In the currently planned paradigm for Crossrail, Canary Wharf is purely a destination.
In Munich, there is a new line toward the airport, with some tunneling on airport grounds as well as at two intermediate suburban stations. There is also a short above-ground spur connecting the airport to the western side of the S-Bahn, giving it two different routes to city center. Finally, there is a short tunnel slightly to the west of the main trunk tunnel to better connect S7 to the mainline.
Why are airports so prominent on this list?
The concept of using strategic tunnels to build new spurs and loops to connect mainlines to new destinations has nothing to do with airports. And yet, so many of these spurs connect to airports: Charles de Gaulle, Heathrow, Zurich, Munich. There are many more such examples, on regional or intercity lines: Schiphol, Arlanda, Ben-Gurion, soon-to-be Berlin-Brandenburg, Barajas. Why is that?
The answer is that the purpose of a spur or loop is to connect to a destination off the mainline. European cities for the most part developed around the railway or metro line. Virtually every important destination in London is on a legacy railway because during the city’s 19th and early 20th century growth period, the railway was the only way to get to Central London. Airports are consistent exceptions because they’re so land-intensive that it’s hard to site them near existing railways.
Where non-airport destinations somehow had to be developed away from the mainline, they’re attractive targets for spurs as well. Canary Wharf sits on the site of a disused dock, which generated some freight rail traffic but little demand for passenger rail. Cergy is one of several new towns built around Paris to act as suburban growth nodes, together with Marne-la-Vallée and Évry (served on a loop of the RER D).
In smaller cities than Paris and London, suburban growth often came together with a metro line. In Stockholm, the Metro was planned together with public housing projects, so many of the Million Program projects are right next to stations, facilitating high public transportation usage. There’s usually no need to build many new regional rail spurs, because such sites are close enough to the center for metro service to be quick enough.
The situation of regional rail in Israel
In Israel, urban development has ignored the railway almost entirely. The colonial network was weak and barely served the state’s travel needs. Investment was minimal, as the state’s political goals were population dispersal and Judaization of peripheral areas rather than efficient transportation. Towns were built around the road network, connected to one another by bus since people were too poor to afford cars.
Rail revival began in the early 1990s with the opening of the Ayalon Railway, providing through-service between points north and south of Tel Aviv. In the generation since, ridership has grown prodigiously, albeit from low initial levels, and the state has built new lines, with an ongoing project to electrify most of the passenger network. However, since the cities came first and the trains second, the new lines do not enter city centers, but rather serve them peripherally near the highway, often surrounded by parking.
Thus, Netanya’s train station is located to the east of the city’s built-up area, on the wrong side of the Route 2 freeway. Ashdod’s train station is on the periphery at a highway interchange, well to the east of city center. Ashkelon’s station is on the eastern margin. The under-construction line through Kfar Saba and Ra’anana passes just south of the built-up area.
In all of these cases, doing it right would require, or would have required, just short, strategic elevated or underground lines:
- Netanya is at the northern end of the Tel Aviv commuter rail network, and so it can easily be served by a spur. The existing station can be retained as a junction for intercity rail service, but building a commuter rail spur would not compromise frequency. Such a spur would require no more than 2 km of tunnel.
- In Ashdod and Ashkelon, there are north-south arterials that are so wide, 50-60 meters, that they could host cut-and-cover subways, effectively moving the line to the west to serve those cities better. In Ashdod there is a decision between going under B’nai Brith, which offers a more convenient through-route, and Herzl, which is more central but requires some boring at the southern end of the city.
- In Kfar Saba and Ra’anana, about 8 km of tunnel under Weizmann and Ahuza are needed, and could potentially be done cut-and-cover as well, but these streets are 30 meters rather than 50 meters wide. Such a route would replace the under-construction combination of a freeway and railway.
- In Rishon LeZion, a 6km route, not all underground, is needed to connect Rishonim with Moshe Dayan via city center and the College of Management rather than via the under construction freeway route avoiding these destinations.
Unfortunately, so far the state’s investment plans keep skirting city centers. It serves them with a cars-and-trains paradigm, which assumes the rail passenger is driving or riding a bus to the train station, never mind that in that case it’s more convenient to drive all the way to one’s destination. This suppresses ridership; not for nothing, the busiest station outside metropolitan centers is Rehovot, with 2.1 million annual entries, and not Ashdod, which is second with 1.9 million. Ashdod is a city of 220,000 and Rehovot one of 140,000, but Rehovot’s station is far more walkable. Were Ashdod not poor, few people would use the station at all – they’d all just drive.
Four years ago I brought up the concept of the small, dense country to argue in favor of full electrification in Israel, Belgium, and the Netherlands. Right now I am going to dredge up this concept again, in the context of intercity trains. In a geographically small country, the value of very high speed is low, since trains do not have stretches of hundreds of kilometers over which 300 km/h has a big advantage over 200 km/h; if this country is dense, then furthermore there are likely to be significant cities are regular intervals, and stopping at them would eliminate whatever advantage high-speed rail had left.
Nonetheless, unlike with electrification, with high-speed rail there is a significant difference between Israel and the Low Countries. Israel does not have economic ties with its neighbors, even ones with which it does have diplomatic relationships, that are strong enough to justify international high-speed rail. Belgium and the Netherlands do – the high-speed rail they do have is already internationally-oriented – and their problem is that they have not quite completed their systems, leading to low average speeds.
The situation in Israel
Israel is a country of 20,000 square kilometers, with about 9 million people. Both figures exclude the entirety of the Territories, which are not served by intercity trains anyway, and have such geography that not even the most ardent annexationists propose to build any.
The country is long and narrow, and the maximum north-south distance is almost 500 km, but the cities at the ends are very small, and the population density in the South is exceptionally low. Eilat, at the southern tip of the country, is a city of 52,000, and is 170 km from the nearest Israeli city, Dimona. A low-speed line for freight may be appropriate for this geography, offering an alternative to the Suez Canal, but there is no real point in investing in high passenger rail speed. For purposes of fast intercity trains, the southern end of Israel is Beer Sheva, less than 100 km from Tel Aviv.
In the Galilee the situation is not quite as stark. The main barrier to intercity rail development is not low population density – on the contrary, the Galilee averages around 400 people per km^2, not counting the Golan Heights. Rather, the physical and urban geographies are formidable barriers: the mountainous topography forces all railroads that want to average reasonable speed to tunnel, and the cities are not aligned on linear corridors, nor are there very large agglomerations except Nazareth, which is about 100 km north of Tel Aviv. A low-speed rail network would be valuable, tunneling only under mountainous cities like Nazareth and Safed, but even 200 km/h in this region is a stretch, let alone 300. Thus, just as the southern limit of any fast intercity rail planning in Israel should be Beer Sheva, the northern limits should be Haifa and Nazareth.
The box formed by Haifa, Nazareth, Jerusalem, Tel Aviv, and Beer Sheva, less than 200 km on its long side, is not appropriate geography for high-speed rail. It is, however, perfect for medium-speed rail, topping at 160 or 200 km/h. The Tel Aviv-Jerusalem high-speed line, built because the legacy line is so curvy that it is substantially slower than a bus, only runs at 160 km/h for this reason – the distance along the railway between the two cities is 57 km and there’s an intermediate airport stop, so the incremental benefit of running faster is small. The Tel Aviv-Haifa line, built in stages in the 1930s and 50s, runs in the Coastal Plain and is largely straight, capable of 160 km/h or even faster. The Tel Aviv-Beer Sheva line is slower, but it too can be upgraded. In all of these cases, the target average speed is about 120 km/h or perhaps a little faster. A high-speed train would do better, but reducing trip times from 40 minutes to 30 just isn’t worth the expense of a new line.
Nazareth is the odd one out among the major cities, lacking a rail connection. This is for both geographical and sociopolitical reasons: it is on a hill, and it is Arab. Reaching Nazareth from the south is eminently possible, on a line branching from the Coastal Railway in the vicinity of Pardes Hanna, continuing northeast along Route 65 through Kafr Qara and Umm al-Fahm, and entering the city via Afula. Modern EMUs can climb the grades around Umm al-Fahm with little trouble, and only about 4 km of tunnel are required to reach Nazareth, including a mined underground station for the city. Continuing onward requires perhaps 8 km of tunnel.
However, so far Israel Railways has been reticent to enter city centers on tunnels or els. Instead, it serves cities on the periphery of their built-up areas or in freeway medians. It would require little tunneling to enter the center of Netanya or Rishon LeTsiyon, and none to enter that of Ashdod or Ashkelon. This is the result of incompetence, as well as some NIMBYism in the case of Rishon. Nonetheless, such short tunnels are the right choice for regional and intercity rail in those cities as well as in Nazareth, which poor as it is remains the center of Israel’s fourth largest urban agglomeration.
What if there is peace?
In Belgium and the Netherlands, there is 300 km/h high-speed rail, justified by international connections to France and Germany. What if Israel reaches a peace agreement with the Palestinians that thaws its relationships with the rest of the Arab world, justifying international connections to present-day enemy states like Syria and Lebanon as well as to cold friends like Jordan and Egypt?
The answer is that the Levant writ large, too, is a relatively small, dense area. The Palestinian Territories have even higher population density than Israel, as does Lebanon. Jordan and Syria, on the desert side of the mountains, are less dense, but if one drops their low-density areas just as one would drop Israel south of Beer Sheva, the box within which to build intercity trains is not particularly large either.
Amman is 72 km from Jerusalem; it’s an attractive target for a continuation of the Tel Aviv-Jerusalem railway at 160-200 km/h, the main difficulty being the grades down to and up from the Jordan Valley. Beirut and Damascus are both about 240 km from Tel Aviv on the most likely rail routes, via the coast up to Beirut and via Nazareth and Safed up to Damascus. The only connection at a truly compelling distance for 300 km/h rail is to Aleppo, which is not large enough and is unlikely to generate enough ridership across the language and political barrier to be worth it.
Egypt presents a more attractive case. Cairo is enormous, and there is a whole lot of nothing between it and the Gaza Strip, a perfect situation for high-speed rail. However, this is firmly in “we’ll cross that bridge when we get to it” territory, as none of the required construction really affects present-day Israeli intercity rail planning. It’s not like the Levantine Arab capitals, all of which lie along extensions of important domestic Israeli routes.
Integrated timed transfers
The Netherlands and Switzerland both have national rail networks based on the idea of an integrated timed transfer, in which trains from many destinations are designed to reach major nodes all at the same time, so that people can connect easily. In Switzerland, trains arrive at every major city just before :00 and :30 every hour and depart just after, and rail infrastructure construction is designed to enable trains to connect cities in integer multiples of half hours. For example, since trains connected Zurich and Basel with Bern in more than an hour, SBB built a 200 km/h line from Olten to Bern, shortening the trip time to just less than an hour to facilitate connections. Every half hour this line carries a burst of four trains in seven minutes in each direction, to ensure trains from many different destinations can connect at Bern at the right time.
I have argued against this approach in the context of Germany, proposing high–speed rail instead specifically on the grounds that Germany is a large country with many pairs of large cities 500 km apart. In the context of the Netherlands, the integrated timed transfer approach is far superior, which is why it is adopting this approach and refining it in ways that go beyond Switzerland’s decentralized planning. Belgium, too, had better adapt the Swiss and Dutch planning approach. What about Israel?
In Israel, timed transfers are essential to any intercity rail build-out. However, a fully integrated approach is more difficult, for three geographical and historical reasons. First, most intercity traffic flows through one two-track mainline, the Coastal Railway. Using advanced rail signaling to permit many trains to enter Tel Aviv at once is fine, but it would not be the everywhere-to-everywhere system of more polycentric countries like Switzerland.
Second, Israeli metro areas are really a mixture of the mostly-monocentric contiguous sprawl of France and the Anglosphere and the polycentric regions of distinct cities of the Netherlands and the German-speaking world. Jerusalem’s agglomeration is entirely Anglo-French in this typology, without significant independent cores, and Tel Aviv and Haifa both have substantial Anglo-French cores ringed by far less important secondary centers. The significant secondary centers around Tel Aviv and Haifa are edge cities within the built-up area that may be near a rail line, like Herzliya Pituah and the Kiryon, but are never independent town centers like the various Randstad and Rhine-Ruhr cities.
And third, Israel completely lacks the large railway terminals of Western countries that built their mainlines in the 19th century. Integrated pulses require one station track per branch coming out of the station, since the point of such timetables is to have trains from all branches arrive at the station at once. Within Germany there is criticism of the Stuttgart 21 project on the grounds that the new underground Stuttgart station will only have eight tracks, whereas there are about 14 planned branches coming out of the city.
So does this mean timed transfers are a bad idea? Absolutely not. Israel Railways must plan around timed transfers at junction stations like Lod, the closest thing the Tel Aviv region has to a German-style secondary core, as well as at future branch points. Entering secondary city centers like Netanya and Ashdod would involve tunnels and els, but more significantly to the national network, these would all be branches, and adding more branches to the mainline would require planning better transfers at the branch points and in the center.
Moreover, Israel still has significant intercity bus service, and most likely always will. Timed connections between buses and trains at outlying terminals like Ashdod are a must, and nationwide coordination of bus schedules to enable such connections is a must as well.
Intercity rail for a small, dense country
The situation in Israel – as in Belgium and the Netherlands – favors a different kind of rail development from that of larger countries like France and Japan. Short distances between major urban areas, frequent stops for intermediate cities, and cities that are not really located along easy lines call for the following design principles:
- The maximum speed should be 160-200 km/h – lines should not be designed for higher speed if that requires more tunneling or bypassing existing mainlines, unless there is a compelling international link.
- All trains should be electric, and run electric multiple units (EMUs) rather than locomotives, making use of EMUs’ fast acceleration to serve many stops.
- Significant cities that do not have rail links or have circuitous links should get new lines, using short tunnels or viaducts if necessary to reach their centers.
- Transfers at junction stations should be timed, as should transfers between buses and trains in cities with significant travel volumes to areas not served by the railway.
- The state should coordinate timetables and fares at the national level and engage in nationwide integrated planning, since a change in one city can propagate on the schedule 100-200 km away.
In Israel, public transportation planners understand some of these points but not others. Rail planning is based on medium rather than high speed; there are some calls for a high-speed train to Eilat, but so far what I’ve seen is at least partly about freight rather than passengers. The state is electrifying most (though not all) of its rail network – but it’s buying electric locomotives as well as EMUs. New rail lines go in freeway medians and on tangents to built-up areas, as if they were 300 km/h lines, rather than low-speed regional lines for which if people have to drive 5 km they may as well drive the remaining 50 to their destination. Schedule coordination is a mess, especially when buses are involved.
Going forward, Israel should aim to have what the Netherlands has, and even more, since the Netherlands has not fully electrified its network, unlike Switzerland. Israel should aim for very high traffic density, connecting the major cities at a top speed of 160-200 km/h and average speed of about 120 km/h, with easy transfers to slightly slower regional lines and to buses. Its cities may not be Tokyo or Paris, but they’re large enough to generate heavy intercity traffic by public transportation, provided the rail network is there.
A few years ago, Sandy Johnston remarked that Jerusalem had the least gridded street network he ever saw, and this complicates any surface transit planning there. At the time he was familiar with New England already, but Jerusalem seemed different.
Here are street maps of West Jerusalem and Boston, at the same scale:
Boston has some gridded sub-areas, like Back Bay, but Downtown Boston is as messy as Jerusalem, and on the level of arterial streets, even the rest of the city isn’t too different. The real issue affecting Jerusalem is the hilly topography. Once one gets out of the core of West Jerusalem, the city turns into a mess of hills with internal street networks and poor connectivity between them. Boston maintains a coherent structure of arterial streets that host buses and tramways, with a cobweb structure that feeds the subway efficiently; in Jerusalem, there is little chance of that.
Surface vs. rapid transit
Rapid transit is mostly insensitive to hills. A subway can be built across hills, partly underground, partly elevated. This is the case in Upper Manhattan, where the 1 train runs in a mix of cut-and-cover subway, elevated structures, and mined deep-level tunnel.
Even if the hills slope down into the natural arterial, this is not such a problem. Train stations can incorporate escalator access and have exits at different elevations. New York manages this in the same neighborhood where the 1 runs, in Washington Heights, on the A train. Monaco, on a sloping hill, manages the same at its train station, which is located underground, using elevator access from multiple neighborhoods at different altitudes.
The deep mining required for such construction doesn’t even raise costs that much. If it’s possible to secure horizontal access to the station site, construction becomes easier. Moreover, running elevated through the valleys, as the 1 does in Manhattan Valley and Inwood, cuts costs rather than increasing them.
Evidently, the hilliness of Rome has not prevented the city from building a subway. Line C’s construction costs were very high, but not because of topography but because of millennia-old archeology, which is not really a question of the street network.
Since rapid transit is not affected as much by hills as surface transit, a city with hilly topography should be biased toward rapid transit and against surface transit. This does not mean every flat city should be content with surface transit and every steep city should build subways and els, but it does mean that the population and density thresholds for rapid transit are smaller in hillier cities.
Some cities are very hilly, but this does not affect their street networks. San Francisco is famous for this: north of Market, in neighborhoods like Telegraph Hill and Russian Hill, the street grid continues mostly uninterrupted, and the result is famously steep streets. In these cities, transit network planning need not pay much attention to the topography: the only concession that need be made is that agencies should preferentially electrify and run trolleybuses, which have better hill-climbing performance than diesel buses – as San Francisco Muni in fact has, retaining trolleybuses rather than replacing them with diesels as nearly all other American cities have.
The more interesting and difficult case is when the street network respects the hills. It can naturally turn the city’s street layout into that of multiple distinct pods, each surrounding a different hill. This is popular in Jerusalem, especially the settlements within East Jerusalem, but also in some of the newer parts of West Jerusalem. There is not much connectivity between these different pods: there may be a single arterial road with the rest of the city, as is the case for the settlements of Pisgat Ze’ev, Ramot, and Ramat Shlomo.
This kind of pod development is popular in a lot of auto-oriented suburbia. The cul-de-sac is a defining feature of many an American suburb. However, in Jerusalem we see it happen even in the context of a dense city: Jerusalem proper has a density of 7,200 people per square kilometer, and all the settlements in question are within the jurisdiction of the city. It comes out of a combination of modernist central planning (Israeli neighborhoods and cities are designed top-down, rather than expanding piecemeal as in North America or France) and the hilly terrain.
Transit planning for such a city is a chore. In theory, choke points are good for transit, because they have high intensity of travel, where dedicated lanes can make buses very efficient. In practice, choke points work for transit only when there are coherent corridors on both sides for the buses to feed. For example, on a wide river spanned by few bridges, buses can run on the bridges, and then continue on the arterials feeding them on either side. Pod development, in contrast, has no coherent arterials within each pod, just collector roads feeding the main drag. Buses can still run on these streets, but there is no structure to the density that encourages them to serve particular locations and not others.
One solution is a type of transit that is overused in flatter cities: the direct express bus, or open BRT. This bus runs local within each pod and then continues on the arterial, making few stops; it could run as open BRT if the arterial has enough development to justify such service, or as a nonstop express service if it is a full freeway. This form of transit developed for both low-density American suburbia and Israeli pod development towns (where this is buttressed by the tendency of the ultra-Orthodox to travel in large families, in which case transfer penalties are much higher, encouraging low-frequency direct service).
Another solution is to go in the air. Gondola lifts are seeing increasing use in extremely hilly cities, where surface transit must wend its way through switchbacks. Medellin’s Metrocable has a vertical rise of 400 meters. Even in cities that are less steep, gondolas could be a solution if arterial roads are simply not available. In the Arab neighborhoods of East Jerusalem, arterials are rarely available, and gondolas bridging ravines could be of use. Gondolas could also be useful for neighborhoods that are only connected by arterial in a radial rather than circumferential direction – they could again bridge ravines to connect peripheral neighborhoods to one another rather than just to the center.
Following up on my last post’s promise to tackle both cultural theory of risk and cultural cringe, here is my take on the latter issue.
It is normal for people to have some degree of national pride and fervor. Cultural cringe refers to the opposite trend: when, in some circumstances, people in certain countries feel national shame and develop an inferiority complex. The term cultural cringe itself was coined by A. A. Phillips in 1950, describing Australia’s inferiority complex toward Britain in literary fields: Australians thought their literature was too provincial and perhaps too incomprehensible to the British readers, and as a result many authors were uncomfortable making the local references celebrated in the literary canon of Britain, France, Russia, the US, etc. This notion has been generalized elsewhere. Amos Oz says he felt uncomfortable writing books in such a peripheral country as Israel until he read Sherwood Anderson’s Winesburg, Ohio, showing how literature of and by the provinces can thrive.
From its origin in Australian literature, the idea of the cultural cringe has expanded to other fields, including the law, social relations, technology, and business. It seems endemic in former colonies, especially ones that are not rich. One writer in Nigeria argues how best practices thinking is cultural cringe by giving an example of a recent legal importation that turns out to already exist in traditional Yoruba law. In Australia itself, political scientist L. J. Hume pushed back against the notion that there is cultural cringe, arguing it is true of literature but not economics of other fields. But in mass culture, the vast majority of countries, both developed and developing, consider American film and television superior to their own and have domestic industries that focus on arthouse films or low-budget flicks.
Cultural cringe in legal, political, or technological fields remains endemic in many other developed countries. In one recent example, Emmanuel Macron said France is inherently resistant to change and (by implication) ungovernable, comparing it negatively with Denmark. In business, 1980s-era America was replete with books telling managers how to think like a Japanese or German, which trend ended when the Japanese lost decade and the economic crisis of German unification made these countries less fashionable.
Lying in the intersection of business, politics, and technology, urbanism and transportation are amenable to analysis using this concept. As in the Nigerian example, the third world tends to have too much cultural cringe and too much faith in the merits of importing first-world methods. Conversely, the United States (and to a large extent Canada) today is resistant to outside ideas and does not know how to be a periphery.
Urban layout: there’s a world outside Europe
During the SB 827 debate in California, supporters reassured restive city residents that the density the bill promoted – up to 7 floors right next to transit lines and up to 5 a little farther away – was gentle. “Paris density,” they said. Everyone likes Paris as a tourist. Everyone recognizes Paris as good urbanism.
There is very little cultural cringe in the United States – on the contrary, Americans are solipsistic in every field. However, one of very few exceptions is that the American middle class vacations in Europe and is familiar with how walkable European cities are. (It’s even referenced on Mad Men when a minor character goes on walks in their car-oriented New York suburb.) Paris is the largest and richest city Americans of a certain wealth and education level can be expected to be familiar with and like, but by the same token the YIMBYs could mention Barcelona, Amsterdam, and Rome.
But it’s useful to think of what was not mentioned. Certainly not Hong Kong or Dubai, which seem to be mentioned almost exclusively negatively in Western discourse. Not Tokyo, which Westerners are much less likely to visit to the point that the Western blogs talking about Japanese urbanism (like Urban Kchoze) are notable for it. Nothing in the middle-income world, including some old cities (like Mexico City and Istanbul) that have building height, street width, and stylistic variation that first-world urbanists would approve of (and do if they’ve been there).
In this situation, the invocation of famous European cities feels less like a dialogue and more like an attempt to induce cringe defensively, to make people feel less attached to their cities’ American auto-oriented character. In effect, it’s an attack on “it will change the character of our neighborhood,” a line that’s much less common in countries that are used to thinking of themselves as inferior to whatever they consider the metropolitan core (such as the first world writ large in Israel, or the former colonial master in ex-colonies).
Transportation: a little cringe is good, but not too much
In the developing world, there is extensive cringe. Without using that term, I suggested it as a reason behind high construction costs in the third world, which are similar to the costs of the first world today and several times as high as those of the first world from back when its income levels were comparable to those of subway-building third-world countries, in the early 1900s. In Latin America and China, development is more inward-looking, and China in particular learned to build subways from the USSR in the 1950s, not a rich country. In former colonies, there seems to be a greater willingness to import methods from either the former colonizer or from countries that aggressively invest in third-world infrastructure, like Japan and China; the result is very high construction costs for projects for which I have data in India and other countries of that development level.
In some cases, like India’s high-speed rail program, the country imports technology wholesale, and Japan (or China) may insist on an exact copy of its methods. As it is, Japan refuses to call Taiwan High-Speed Rail a Shinkansen system even though it runs Shinkansen rolling stock: construction methods were European, so Japan only calls THSR a high-speed rail system using Shinkansen-based technology.
However, decisions like India’s standard-gauge metro lines happen even in indigenous systems. Delhi Metro uses standard gauge not for some turnkey technological import, but purely because it feels more modern whereas Indian mainline trains feel dinghy and dangerous. Evidently, Delhi Metro electrification is 25 kV, which is standard on mainline trains but unheard of on first-world metros; modifying subways for high-voltage electrification requires expensive concrete pouring, since high-voltage catenary requires more generous clearances to avoid arcing, whereas modifying rail gauge is routine since the European vendors are used to selling to broad-gauge Finland and Spain and the Japanese ones are used to their country’s multitude of gauges.
And if India errs on the side of too much shiny adoption of foreign technology, the US errs on the side of adopting too little. Americans do not think their country is inferior. American authors do not think they need to experience another country or speak another language before they write. There was a time when the American business community felt outcompeted, but today it feels like it’s at the top of the world, Silicon Valley having long left Japanese corporations in the dust; I stopped seeing complaints that American cars were inferior to German and Japanese ones not long after Obama’s auto industry bailout.
The American policy sphere seems especially constrained. There is some cultural cringe toward London, leading thinktanks like the Regional Plan Association and TransitCenter to overlearn from London’s peculiarities (like the Oyster fare cap and contactless credit card payment), but not much toward Continental Europe and practically none toward Japan. Instead, the attitude toward non-English-speaking countries is one of dismissal. When Richard Mlynarik pointed out to a Caltrain official consultant that Japanese trains turned much faster at terminals than Caltrain thought possible, the consultant replied, “Asians don’t value life the way we do.” (Update 2020-09-05: since a bunch of people in the Bay Area reference this line, I am reminded that this was not a public employee of Caltrain but a consultant brought in for the Transbay Terminal project.)
If India fails to understand where its own methods could be superior despite being a peripheral country, the United States fails to understand that it’s a peripheral country in the first place. Transportation innovation rarely happens in North America. It happens in Western Europe and Japan, and to some extent in developing countries that have less cultural cringe than former colonies, such as Brazil and Colombia and their invention of BRT or Colombia, Bolivia, and Mexico’s use of aerial gondolas in mountainous suburban areas.
Urban development: you are not New York
I’ve been reading Aaron Renn’s blog, the Urbanophile, since maybe 2008. At the time he was still in Indianapolis, in (I believe) management consulting, writing about how his city was trying to become culturally and economically bigger than it was, and sometimes but not always succeeding. A recurrent theme in his writings has been that Midwestern American cities are desperate for development. They keep saying they need more creative people, more venture capital, or whatever else is in vogue. (In contrast, he says, Rhode Island, where he lived later, doesn’t even understand how peripheral it is.)
However, the way the Midwestern cities he focuses on try to attract this elusive development is through cheap copying. An old post of his I can no longer find contrasts world-class Indianapolis with world class in Indianapolis. The former involves investing in some city institution to make it world-class, or more realistically notable enough that boosters can call it world-class with a straight face. The latter involves inviting a starchitect or another person with international cachet (such as Richard Florida) to build something in Indianapolis that’s notable and is exactly as notable as what this person might build in any other city of that size, with no particular connection to the city itself.
In the transportation field, many American cities build mixed-traffic downtown streetcars and beam with pride if they get 4,000 riders per weekday. Often this mentality overrides any attempt to provide services to city residents: thus, the streetcar in Detroit is not integrated with the city’s bus network, and in fact a bus runs on the same street, on different lanes from the streetcar. This isn’t about some mythical preference for rail over bus: these cities build whatever they hear is in vogue and will get them noticed by New York media, whether it’s peak-only commuter rail, a downtown streetcar, a limited bus that calls itself BRT, or now a bus network redesign around untimed 15-minute frequencies.
Cringe vs. dialogue
It’s important to distinguish dialogue with a foreign culture and cultural cringe toward it. One difference is that cringe implies infatuation; however, infatuation can also develop among immigrants who are steeped in the metropole’s culture after having lived there even while maintaining ties to the old country. A bigger difference is the extent of two-way dialogue. Israelis use the expression “unbroken country” to refer to the mythical average first-world country in which you can get things done without having to tell government bureaucrats that you served in the military with their bosses; however, few have lived abroad long enough to know the details of what makes these countries tick better.
With limited knowledge of the core, the periphery can worship at the feet of the few people who do know, which leads to political bias. This is where moral panics of no-go zones come from: there is an Israeli television show purporting to portray how things are in Europe, but any connection between Belleville (or other racially diverse Paris neighborhoods) and what they depict is completely incidental. In that case, the bias is right-wing. In the opposite direction, left-wing bias can occur when American liberals and socialists are enamored by European health care and education systems and elide a thousand details that distinguish them from American renditions of single-payer health care or free college tuition.
But the biased reaction is only common in places that care little about how to govern. “Well, actually Tower Hamlets is a no-go zone” is not a blueprint for reducing nonwhite immigration to the United States or Israel. Instead, in the policy sphere a more common reaction is a shrug. Dialogue is threatening: the people capable of it are typically not the top pundits on this issue. Instead, it’s more common to aggressively dismiss knowledge that’s hard to access, even among people who at the same time invoke the cringe. In Israel it takes the form of self-denigrating lines like “this is Israel, not Finland.” Cultural cringe leads to lower expectations this way.
When Phillips criticized Australian authors who deracinated their writing to appeal to British taste, he was implicitly saying that Australians couldn’t root their literature in British experience. Oz, similarly, felt constrained about writing when he was young because living in Israel, he could not root his books in Paris, Milan, and other flashy cities whose books he devoured. The economic (or legal, or technological) analogue of this observation is that the reason there is cultural cringe is that people in peripheral areas (which in transportation include the United States) are too unfamiliar with the core and cannot dialogue with it the way people in different parts of the core can.
Urbanism is not literature. One doesn’t need extraordinary sensitivity and a lifetime (short as it may be) in a culture to produce very good insights about transportation, housing, or municipal governance. It’s possible to break out of the cringe by acquiring detailed knowledge of how the core operates. In the case of the third world and subway construction, it means learning enough about current and historical construction methods to be able to propose ways to build infrastructure at low costs commensurate with these cities’ low wages; in the case of the United States, it means learning enough about what makes European, Japanese, Latin American, etc. urbanism tick that it can be adopted domestically.
Urbanism is not literature in a far more important sense: there really are better and worse traditions there. It’s not enough to have pride in what you have when what you have is a third-world city where the poor don’t have running water, or for that matter an American city that would shut down instantly were gas prices to rise to levels necessary to stop global warming. Learning from the core is crucial. It’s just equally important to do so through dialogue and not through the ignorant self-denigration that is cultural cringe.
The American discourse about gentrification is full of stereotypes that the participants don’t recognize as such. For example, a widely-shared Buzzfeed article created an entire theory out of a single busybody who was responsible for half of the police complaints on their West Harlem block. The main check on stereotypes – “that’s racist” – only works when the stereotypes resemble the forms of racism society is most familiar with. The history of white racism against black people in the US is so different that it colors what Americans perceive as racial stereotypes and what they don’t. So as public service, I’d like to give some examples to draw commonalities between stereotypes in other cities I’ve lived in (Tel Aviv, Vancouver, Paris) and familiar anti-gentrification rhetoric.
Last decade, there was an influx of black refugees into working-class areas of South Tel Aviv, centered on Levinsky Park. The area is underpriced relative to its job access, courtesy of Central Bus Station, a failed urban renewal project that attracted crime; already in the 1990s it was nicknamed Central Stench (tsaḥana merkazit; Central Station is taḥana merkazit) and lampooned in a popular comic as a literal gateway to hell. The neighborhood’s response was violent, and the discourse within Israel is divided into people who wish the refugees imprisoned and deported from the country and people who wish them forcibly dispersed around the country.
Other parts of South Tel Aviv have been gentrifying since the 1990s, centered on Florentin. South Tel Aviv’s right-wing Jewish working class began connecting the two trends. A few years ago I saw a widely-shared Facebook post claiming that the influx of black refugees is deliberately engineered by developers as a ploy to gentrify the neighborhood. The theory, as I recall, is that black people are so odious that developers are using them to engineer white flight, after which they’ll evict the refugees, demolish the neighborhood’s mid-rise housing stock, and erect luxury towers.
In the last decade or so Vancouver has seen rising rents and even faster-rising housing prices, and the region’s white population is blaming Chinese people. In 2016, British Columbia passed a 15% tax on residential buyers who are not Canadian citizens or permanent residents; the tax was phrased neutrally, but the target was predominantly Chinese, and 21% of correspondence from citizens to the government on the issue was explicitly Sinophobic. In a city with rapid immigration, it should not be a surprise that new buyers tend to be immigrants, often on work or investor visas, but the region has a moral panic about Chinese people buying condos and houses as investments and leaving them empty.
The specific stereotypes of Chinese people in Vancouver vary. When I lived in Vancouver I encountered some light generic stereotyping (“people in Richmond are aggressive drivers”), but nothing connoting poverty, even though Richmond is poorer than Surrey, which some people I met compared with Camden, New Jersey. The language I see in the media concerning housing goes the other way: Chinese immigrants are stereotyped as oligarchs laundering ill-begotten wealth.
Like people in every other highly-toured region, Parisians hate the tourists. Seeing small declines in city population over the 2009-14 period, city electeds decided to blame Airbnb, and not, say, low housing construction rates (raising rents), a falling birth rate, or commercialization in city center. The mayor of the 1st arrondissement, Jean-Francois Legaret, called Airbnb “a true catastrophe for Central Paris.” The 1st arrondissement has high residential incomes; the lower-income parts of the city are the 10th, 11th, 13th, 18th, 19th, and 20th.
Rich and poor stereotypes
An ethnic or national group can stereotype another group as rich, poor, or both. White stereotypes of black people in the US and Europe are, within each ethnic group, associated with poverty: crime, aggressive physicality, laziness, indifference to education, proclivity for certain kinds of music and sport. Anti-Semitism today invokes stereotypes of the rich: greed, political subversion, disloyalty to the nation, corruption, success with money. Islamophobic stereotypes tend toward stereotypes of poverty, but are sometimes also bundled with stereotypes of Gulf money. In the last few decades Sinophobic stereotypes transitioned from ones of poverty (treating the Chinese as a faceless horde) to ones of wealth, similar to anti-Semitic stereotypes, to the point that people in Vancouver forget Richmond’s low incomes and people in New York forget the high poverty rates of Asian-New Yorkers and the overcrowding in Chinatown.
But as in the case of South Tel Aviv, the stereotypes can merge. The racists in South Tel Aviv blend two groups they hate – middle-class leftists and poor non-Jews – into one mass, blaming them for a trend that is usually blamed on the rich and the middle class. Historically, anti-Semitism was fully blended: the Jew was simultaneously poor and rich, wretched and exploitative, communist and capitalist, overly studious and overly physical. This blending of stereotypes was overt in Nazi propaganda, but also in the softer anti-Semitism directed against immigrants to the US.
The urban as a foreigner
Nationalists and populists stereotype cities like prewar anti-Semites stereotype Jews. The urban poor are lazy criminals, the rural poor are honest workers; the urban rich are exploitative capitalists sucking life out of the country, the rural rich are successful small business leaders; the urban middle class are bo-bo globalists, the rural middle class is the very definition of normality. This mentality is hard to miss in anti-urbanist writers like Joel Kotkin, and more recently in articles trying to portray an opposition between the Real Country (in the US but also in Israel and France) and the Urban Elites.
The definition of what is rural and what is urban is fractal. In the South, Long Island is part of New York; on Long Island, Long Island is Real America, distinct from the city that Long Island’s residents fled in the 1950s and 60s. Within cities the Real Country vs. Urban Elite opposition can involve the outer city vs. the inner city, as in Toronto, where Rob Ford won the mayoral election by appealing to outer-urban resentment of David Miller’s attempt to redistribute street space from cars to public transit. But it is in many cases demographic rather than geographic: the newcomer is the new rootless cosmopolitan.
In this mentality, the newcomer can be a rich gentrifier displacing honest salt-of-the-earth third-generation residents by paying higher rents or a refugee doing the same through living multiple people to a bedroom (or even both, in the case of some San Francisco programmers). In either case, the newcomer is a foreigner who doesn’t belong to the city’s culture and does not deserve the same access to city resources. People who build housing for this foreigner are inherently suspect, as are businesses that cater to the foreigner’s tastes. The demands – removal of access to housing – are the same regardless of whether the foreigners so stereotyped are poor or rich, and the stereotypes of wealth and poverty mix easily. That anti-gentrification activism looks so similar regardless of which social class it targets suggests that ultimately, any argument made is an excuse justifying not liking outsiders very much.
Continuing from last week’s post about signaling costs, here is what I’ve found about electrification costs.
Like signaling, electrification usually doesn’t make the industry press, and therefore there are fewer examples than I’d like. Moreover, the examples with concrete costs are all in countries where infrastructure costs are high: the US, Canada, the UK, Israel, New Zealand. However, a check using general reported French costs (as opposed to a specific project) suggests there is no premium in Israel and New Zealand over France, even though both countries’ urban rail tunneling projects are more expensive than Parisian Metro and RER extensions.
In the UK, the recent electrification project has stalled due to extreme cost overruns. Finding exact cost figures by segment is difficult in most of the country, but there are specific figures in the Great Western. Financial Times reports the cost of the Great Western project at £2.8 billion, covering 258 km of intercity mainline (mostly double-track, some four-track) and what I believe to be 141 km of commuter rail lines in South Wales, working from Wikipedia’s graphic and subtracting the canceled electrification to Swansea. In PPP dollars it’s around $10 million per km, but the cost may include items I exclude elsewhere in this post, such as rolling stock. For reference, in the late 2000s the project was estimated at £640 million, but costs then tripled, as the plan to automate wire installation turned out not to work. Taking the headline cost as that of the last link, £1.74 billion, the cost is $6.1 million per km, but there have been further overruns since (i.e. the Swansea cancellation).
In the US, there are three projects that I have numbers for. The most expensive of the three is Caltrain electrification, an 80 km project whose headline cost is $1.9 billion. But this includes rolling stock and signaling, and in particular, the CBOSS signaling system has wasted hundreds of millions of dollars. Electrification infrastructure alone is $697 million, or $8.5 million per km. The explanations I’ve read for this high figure include indifference to best practices (e.g. electrification masts are spaced 50 meters apart where 80 meters is more common) and generally poor contracting in the Bay Area.
The other two US projects are more remote, in two different ways. One is California High-Speed Rail: with the latest cost overrun, the projected electrification cost is $3.7 billion (table 4, PDF-p. 14). The length of route to be electrified is unclear: Phase 1, Los Angeles to San Francisco with a short branch up to Merced, is a little more than 700 km, but 80 km of that route is Caltrain, to which the high-speed rail fund is only contributing a partial amount. If the denominator is 700 km then the cost is $5.3 million per km.
The other remote US project is Amtrak’s electrification of the New Haven-Boston segment of the Northeast Corridor in the late 1990s. Back then, the 250-km double-track route was electrified for $600 million, which is $2.4 million per km, or about $3.5 million per km adjusted for inflation.
In Canada, Toronto is in the process of electrifying most of its regional rail network. The current project includes 262 route-km and has a headline cost of $13.5 billion, but according to rail consultant Michael Schabas, this includes new track, extensive junction modification, unnecessary noise walls (totaling $1 billion), and nearly 100% in contingency just because on the original budget the benefit-cost ratio seemed too good to be true. In a 2013 study, the infrastructure cost of full electrification was estimated at $2.37 billion for 450 route-km in 2010 Canadian dollars. In today’s American dollars it’s about $4.5 million per km.
In France, a report that I can no longer find stated that a kilometer of electrification cost a million euros, in the context of the electrification of a single-track legacy branch to Sables d’Olonne, used by some TGV services. While trying to find this report, I saw two different articles claiming the cost of electrification in France to be a million euros per double-track kilometer. The latter article is from 2006, so the cost in today’s money is a little higher, perhaps as high as $1.5 million per km; the article specifically says the cost includes bridge modification to permit sufficient clearances for catenary.
In Israel, the majority of the national network is currently being electrified, and I’ve argued elsewhere for a completist approach owing to the country’s small size, high density, and lack of rail connections with its neighbors. The project has been delayed due to litigation and possibly poor contractor selection, but a recent article on the subject mentions no cost overrun from the original budget of 3 billion shekels, about $750 million, for 600 km of double-track. This is $1.25 million per km and includes not just wire and substations but also 23 years’ worth of maintenance. This may be similar to the Danish ETCS project, which has been severely delayed but is actually coming in slightly under budget.
In New Zealand, the one electrification project recently undertaken, that of the Auckland regional rail network, cost $80 million in infrastructure. This is New Zealand dollars, so in US terms this is closer to $55 million. The total length of the network is about 80 route-km and 200 track-km, making the cost about $700,000 per km. But the project includes much more than wire: the maintenance facility, included in the Israeli figure, cost another NZ $100 million, and it is unclear whether bridge modifications were in the infrastructure contract or tendered separately.
The big takeaway from this dataset, taking French costs as the average (which they are when it comes to infrastructure), is that Israel and New Zealand, both small countries that use extensive foreign expertise, do not pay a premium, unlike the US, UK, and Canada. In the UK, there is a straightforward explanation: Network Rail attempted to automate the process to cut costs, and the automation failed, creating problems that blew up the budget. Premature automation is a general problem in industry: analysts have blamed it for Tesla’s production problems.
In the US and Canada, the construction cost problem is generally severe. However, it’s important to note that at NZ$2.8-3.4 billion for 3.4 km of tunnel, Auckland’s tunneling cost, around US$600 million per km, isn’t much lower than Toronto’s and is actually slightly higher than the Bay Area’s. My explanation for high costs in Israel, India, Bangladesh, Australia, Canada, New Zealand, Singapore, and Hong Kong used to be their shared English common law heritage, but this is contradicted by the lack of any British premium over French costs in the middle of the 20th century. An alternative explanation, also covering some high-cost civil law third-world countries like Indonesia and Egypt, is that these countries all prefer outside consultants to developing public-sector expertise, which in the richer countries is ideologically associated with big government and in the poorer ones doesn’t exist due to problems with corruption. (China and Latin America are corrupt as well, but their heritages of inward-looking development did create local expertise; after the Sino-Soviet split, China had to figure out how to build subways on its own.)
But Israel Railways clearly has no domestic expertise in electrification. The political system is so unused to this technology that earlier this decade I saw activists on the center-left express NIMBY opposition to catenary, citing bogus concerns over radiation, a line of attack I have never seen in California, let alone the Northeastern US. Nor is Israel Railways good at contracting: the constant delays, attributed to poor contractor choice, testify to that. The political hierarchy supports rail electrification as a form of modernization, but Transport Minister Israel Katz is generally hostile to public transit and runs for office with a poster of his face against a background of a freeway interchange.
What’s more likely in my view is that Israel and New Zealand, with no and very little preexisting electrification respectively, invited experts to design a system from scratch based on best industry practices. I’m unfamiliar with the culture of New Zealand, but Israel has extensive cultural cringe with respect to what Israelis call מדינה מתוקנת (“medina metukenet”), an unbroken country. The unbroken country is a pan-first-world mishmash of American, European, and sometimes even East Asian practices. Since the weakness of American rail is well-known to Israelis, Israel has just imported European technology, which in this case appears easy to install, without the more particular sensitivities of urban tunneling (the concrete side of the electronics before concrete maxim). In contrast, the US is solipsistic, insisting on using domestic ideas (designed by consultants, not civil servants). Canada, as far as I can tell, is as solipsistic as the US: its world extends to Canada and the US; Schabas himself had to introduce British ideas of frequent regional rail service to a bureaucracy that assumed regional rail must be run according to North American peak-only practices.
All of this is speculation based on a small number of cases, so caveat emptor. But it’s fairly consistent with infrastructure construction costs, so long as one remembers that the scope for local variation is smaller in electrification and systems than in civil infrastructure (for one, the scope for overbuilding is much more limited). It suggests that North America could reduce its electrification costs dramatically by expanding its worldview to incorporate the same European (or Asian) companies that build its trains and use European (or Asian) standards.
