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 that Japanese trains turned much faster at terminals than Caltrain thought possible, the official replied, “Asians don’t value life the way we do.”
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.
Generally, the best guide to where a city should build rail lines is where the busiest buses are. However, there are exceptions. I have written two posts about this giving examples of exceptions, and am going to give a third exception; I also intend to write a separate post soon giving a fourth exception.
The first post, from four years ago, deals with cases where the bus alignment has to stay on a major street, but some major destinations are just away from the street; a subway can deviate to serve those destinations. Examples include Old Jaffa in Tel Aviv near the north-south spine of bus lines 1 and 25, and Century City near the Wilshire corridor. Here, buses are a good guide to corridor demand, but the rail line should serve microdestinations just outside the corridor.
The second post, from last year, is more properly about corridors. It describes street networks that are hostile to surface transit, by featuring narrow, meandering streets. The main example is Boston, especially the Green Line Extension, in a rail right-of-way in a city infamous for its labyrinthine streets. Another example is the Evergreen extension in Vancouver, serving Coquitlam; the bus the extension replaced, the 97-B, meandered through Coquitlam since the streets were so poorly configured, while the extension uses a short tunnel and runs parallel to a railroad.
In this post I’d like to expand on a point I made, obliquely, in the Voice of San Diego. In San Diego, there’s an under-construction light rail extension, in a rail right-of-way, into an area with not-great bus ridership. Consult the following map:
Preexisting light rail (“Trolley”) is in black, the extension (of the Blue Line) in blue, the parallel north-south arterial in purple, and two buses in green and red. The bus ridership on Ingraham is very low: the bus route running on it, 9, has 1,500 riders per weekday (source). The top bus in San Diego, the 7 (going north of downtown, then east), has 11,000. So on the surface, this suggests there isn’t much demand for north-south transit in that area of the city, called Pacific Beach.
But that’s wrong, because in an auto-oriented city like any US city except New York, the major streets are determined by car access. The relentless grids of so many North American cities – Chicago, Los Angeles, Toronto, Vancouver – are not just where the buses go, but also where the cars go. Even in Manhattan, if you have the misfortune to find yourself going east-west in a car, you will probably use one of the major two-way streets, like 14th or 42nd, which are less clogged than the one-way streets in between. Non-gridded street networks for the most part obey this rule too – the commercial streets tend to be the wider ones used by car through-traffic.
Freeways throw a wrench into this system. They offer a convenient route for cars, but are abominable for commerce. Locations 5 minutes by car from the freeway are good; locations right along the freeway are not, unlike ones right along an arterial road. The main car route from Pacific Beach to the CBD is taking an east-west arterial to the I-5, not going south on Ingraham. This means that the demand for north-south traffic actually shows as strong commerce on east-west streets, hosting bus routes 27 and 30, and not on Ingraham. The 27 has weak ridership, and the 30 has strong ridership but not right along the I-5. But in a sense it doesn’t really matter, because, like the car- and bus-hostile narrow streets of old city centers, the freeway-centric road network in that part of San Diego suppresses bus ridership relative to future rail ridership.
In the presence of rail, the strong routes are the ones orthogonal to the rail line. Here, the 27 and 30 already preexist; there is a planned Trolley stop at the intersection with the 27, and presumably the 30 will be rerouted to serve that intersection rather than to duplicate the trains along the freeway. (I tried talking to the transit agency about this, but didn’t get any useful answers.) So the decent east-west bus ridership in Pacific Beach is actually an argument in favor of a north-south rail extension.
Like every exception to a general rule, this is not a common scenario. So where else are there cases where this special case holds? The necessary elements are,
- The city must be auto-oriented enough that car access is crucial to nearly all commercial drags. In Paris, it doesn’t matter how you reach the Peripherique by car, because car ownership is so low.
- The city should not have a strong mainline rail network, which leads to a hierarchical transit network (buses feeding train stations), in which both buses and cars use the same major streets to reach train stations. This means that Sydney and Melbourne are out, as are German cities short of Berlin and Munich’s transit mode shares.
- The city must have a strong network of urban freeways, disrupting the street network to the point of siphoning traffic away from the surface streets that would otherwise be the main routes.
As it happens, all three elements are present in Tel Aviv. North-south travel within the region uses Ayalon Freeway, inconveniently east of the traditional city center; the city has been building a CBD closer to the freeway, but it’s still not quite there. This suggests that traffic is suppressed on the north-south arterials to the west – Ibn Gabirol (hosting the planned second line of the subway) and Dizengoff (possibly hosting the third) – is suppressed, and those streets require subways. This is in part why, before the Red Line began construction, I argued in favor of putting a north-south subway under Ibn Gabirol, and not under freeway-adjacent Namir Road, where the Red Line goes.
In the future, this pattern suggests that Tel Aviv should make sure to build north-south subways under Ibn Gabirol and Dizengoff, and extend them north. The significance of the northern direction is that the effect I’m describing in this post only works when car ownership is high; Israel is poor enough that car ownership is not universal, and in the poorer southern suburbs it is low enough that the buses do give a good guide to corridor demand, whereas in the northern suburbs everyone owns a car. There is likely to be suppressed transit demand in Herzliya, Ramat HaSharon, and northeastern Tel Aviv (including Ramat HaHayal, an edge city with many tech jobs). Thus ridership on a subway line going elevated over Sokolov in Ramat HaSharon and Herzliya, or on Raoul Wallenberg to Ramat HaHayal, is likely to be higher than present-day bus ridership suggests.
An American example is Washington’s suburbs. The Metro extensions are planned with little regard for bus ridership. While the Silver Line is bad for multiple reasons – high construction costs, service to too far exurbs, too much branching on an overloaded trunk – the extension to Tysons Corner is its one good aspect. There is no point in discussing bus ridership at an edge city like Tysons – conventional buses wouldn’t be following the same route that the cars follow, and freeway express buses almost universally have trivial ridership.
Finally, Vancouver. While Vancouver itself is gridded, its suburbs are much less so. In the suburbs served by the Trans-Canada Highway, especially Surrey, it’s likely that car traffic mostly follows roads feeding the highway. People drive to their jobs in Downtown, Central Broadway, Metrotown, or any of Surrey’s internal centers; there aren’t a lot of park-and-rides at SkyTrain stations, which instead emphasize transit-oriented development, and in Surrey there are actually more park-and-ride spaces at the freeways, with express bus access, than at the one SkyTrain stop with parking, Scott Road. This suggests that there is suppressed bus ridership in Surrey and Langley parallel to the Trans-Canada, along Fraser Highway. Extending SkyTrain in that direction is on a distant priority list for the region, and this theory suggests that it should be moved up, to be just behind the Broadway subway to UBC.
Note: I am going to take some suggestions for post topics in the future. This post comes from a Twitter poll I ran the day before yesterday.
The Yamanote Line in Tokyo is a ring. Trains go around the ring as on any other circular rail line. However, the line is not truly circumferential, since it serves as a north-south trunk through Central Tokyo. In that way, it contrasts with fully circumferential rings, such as the Moscow Circle Line, Seoul Metro Line 2 (see update below), and the under-construction Paris Metro Line 15. It’s really a hybrid of radial and circumferential transit, despite the on-paper circular layout. In previous posts I’ve attacked one kind of mixed line and given criteria for when another kind of mixed line can work. In this post, I’m going to discuss the kind of mixed line Yamanote is: why it works, and in what circumstances other cities can replicate it.
Consider the following diagram:
The red and blue lines are radial. The other three are hybrids. The yellow line is radial, mostly, but skirts city center and acts as a circumferential to its west; this kind of hybrid is nearly always a bad idea. The pink line is radial, but at the eastern end bends to act as a circumferential at the eastern end; this kind of hybrid is uncommon but can work in special cases, for example if Second Avenue Subway in New York is extended west under 125th Street. The green line is a Yamanote-style ring, offering radial service through city center but also circumferential service to the south and west.
On this map, the green line ensures there is circumferential service connecting what are hopefully the major nodes just west and south of city center. It doesn’t do anything for areas north and east of it. This means that this line works better if there is inherently more demand to the west and south than to the east and north. In Tokyo, this is indeed the case: the Yamanote ring offers north-south circumferential service west of Central Tokyo, through what are now the high-density secondary business districts of Ikebukuro, Shinjuku, and Shibuya. East of Central Tokyo, the only really compelling destinations, judging by subway ridership, are Oshiage and Asakusa, and neither is as big as Ikebukuro, Shinjuku, or Shibuya. Toyosu has high subway ridership, but is close enough to the water that it’s hard to build a circumferential through it.
Such a mixed line also becomes more useful if the radial component is better. The radial line can’t extend very far out, since the line needs to form a ring, so it should connect to very high-density neighborhoods just a few stops outside city center, or else provide additional service on an overloaded radial trunk. The Yamanote Line benefits from looking less like a perfect circle and more like upside-down egg, with two elongated north-south legs and two short (one very short) east-west legs; it extends its radial segment slightly farther out than it would otherwise be. In Tokyo, of course, all rail lines serving the center are beyond capacity, so the Yamanote Line’s extra two tracks certainly help; in fact, the two radial lines going north and south of Tokyo Station on parallel tracks, the Tohoku and Tokaido Lines, are two of the three most overcrowded in the city. (The third is the Chuo Line.) There’s even a dedicated local line, Keihin-Tohoku, covering the inner segments of both lines, making the same stops as Yamanote where they are parallel, in addition to the more express, longer-distance Tokaido and Tohoku Main Line trains.
Finally, there should not be radials that miss the mixed line; this is always a danger with subway lines that are neither pure radials nor pure circumferentials. Yamanote avoids this problem because it’s so close to the water at Shimbashi that the north-south subway lines all curve to the west as they go south, intersecting the ring. It’s actually the east-west lines that cross the Yamanote Line without transfers, like Tozai and Hanzomon; the north-south lines intersect the line with transfers.
The obvious caveat here is that while the Yamanote Line functions very well today, historically it did not originate as a circumferential in an area that needed extra service. It was built as a bypass around Central Tokyo, connecting the Tokaido and Tohoku Line at a time when Tokaido still terminated at Shimbashi and Tohoku at Ueno. Tokyo Station only opened 30 years later, and the ring was only completed another 10 years after that. Shinjuku only grew in the first place as the junction between the Yamanote and Chuo Lines, and Ikebukuro and Shibuya grew as the terminals of interwar private suburban railways. When the line opened, in 1885, Tokyo had 1.1 million people; today, the city proper has 9.5 million and the metro area has 38 million. The early rail lines shaped the city as much as it shaped them.
Nonetheless, with the economic geography of Tokyo today, the Yamanote Line works. Even though the history is different, it’s a useful tool for mature cities seeking to build up their rail networks. Provided the principles that make for the Yamanote Line’s success apply – stronger demand for circumferential service on one side of city center than on the others, demand for supplemental inner radial service, and good connections to other lines – this layout can succeed elsewhere.
Waterfront cities should take especial note, since they naturally have one side that potentially has high travel demand and one side that has fish. In those cities, there may be value in running the radial closest to the shoreline in a ring with an inland line.
This does not mean that every waterfront city should consider such a line. On the contrary: non-examples outnumber examples.
In Toronto, using two mainline tracks and connecting them to a ring to provide subway relief could have worked, but there are no good north-south corridors for such a ring (especially on the west), and the only good east-west corridor is Eglinton, which is being built incompatible with mainline rail (and has too much independent value to be closed down and replaced with a mainline link).
In Chicago, the grid makes it hard to branch lines properly: for example, a ring leaving the Red Line heading west at Belmont would necessary have to branch before Belmont Station, cutting frequency to the busiest station in the area. Plans for a circle line from last decade also faced limited demand along individual segments, such as the north-south segment of the Pink Line parallel to Ashland; ultimately, the planned line had too small a radius, with a circumference of 16 km, compared with 34.5 for Yamanote.
In Tel Aviv, there just isn’t any compelling north-south corridor outside the center. There are some strong destinations just east of Ayalon, like the Diamond Exchange and HaTikva, but those are already served by mainline rail. Beyond that, the next batch of strong destinations, just past Highway 4, is so far from Central Tel Aviv that the line would really be two radials connected by a short circumferential, more the London Circle Line when it was a full circle than the Yamanote Line, which is just one radial.
So where would a Yamanote-style circle be useful outside Tokyo? There are semi-plausible examples in New York and Boston.
In New York, it’s at the very least plausible to cut the G off the South Brooklyn Line, and have it enter Manhattan via the Rutgers Street Tunnel, as a branch of the F, replacing the current M train. There is no track connection enabling such service, but it could be constructed just west of Hoyt-Schermerhorn; consult Vanshnookraggen’s new track map. This new G still shouldn’t form a perfect circle (there’s far too much radial demand along the Queens Boulevard Line), but there are plausible arguments why it should, with a short tunnel just west of Court Square: namely, it would provide a faster way into Midtown from Williamsburg and Greenpoint than the overcrowded L.
In Boston, there is a circumferential alignment, from Harvard to JFK-UMass via Brookline, that can get a subway, in what was called the Urban Ring project before it was downgraded to buses. Two of the busiest buses in the region, the 1 and 66, go along or near the route. An extension from Harvard east into Sullivan and Charlestown is pretty straightforward, too. Beyond Charlestown, there are three options, all with costs and benefits: keep the line a semicricle, complete the circle via East Boston and the airport, and complete the circle via the North End and Aquarium. The second option is a pure circumferential, in which South Boston, lying between East Boston and JFK-UMass, would get better service north and south than west to Downtown. The third option cuts off East Boston, the lowest-ridership of the radial legs of the subway, and offers a way into the center from South Boston and Charlestown.
Of note, neither New York nor Boston is a clear example of good use of the Yamanote-style ring. This style of mixed line is rare, depending on the existence of unusually strong circumferential demand on just one side (west in Boston, east in New York), and on the water making it hard to build regular circles. It’s an edge case; but good transit planning revolves around understanding when a city’s circumstances produce an edge case, in which the simplest principles of transit planning (“every subway line should be radial or circumferential”) do not apply.
Update 5/16: commenter Threestationsquare reminds me that Seoul Metro Line 2 is the same kind of ring as Yamanote. The north leg passes through City Hall, near the northern end of the Seoul CBD, providing radial east-west service. The south leg serves a busy secondary commercial core in Gangnam, Tehran Avenue; Gangnam Station itself is the busiest in Seoul, and has sprouted a large secondary CBD.
Vancouver is going to open the Evergreen Line at the end of the year, an 11-km SkyTrain branch to Coquitlam with a projected ridership of 70,000 per weekday; current ridership on the B-line bus paralleling the route, the 97, is 11,000, the 20th busiest citywide (see data here).
New York is going to open the first phase of Second Avenue Subway at the end of the year or early next year, a total of 4 km of new route with projected ridership of 200,000 per day (see pp. 2-3). The bus running down First and Second Avenues, the M15, has 46,000 weekday riders, trading places with two other routes for first citywide, but first phase only covers a quarter of the route, and the ridership projection in case the entire Second Avenue Subway is built is 560,000; nobody expects the other two top bus routes in New York, the B46 on Utica and the Bx12 on Fordham, to support such ridership if they’re ever replaced with subways.
In Boston, the Green Line Extension northwest in Somerville is projected to have 52,000 weekday riders by 2030. There is no single parallel bus, but a few buses serve the same area: the 101 with 4,800 weekday riders, the 89 with 4,200, the 88 with 4,100, and the 87 with 3,800 (all bus ridership data is from the Bluebook, PDF-pp. 48-54); the busiest of these ranks 28th regionwide.
In all three cases, I think the ridership estimates are reasonable. Vancouver especially has a good track record, with Canada Line ridership meeting projections; it’s harder to tell in New York and Boston, which have not opened a rail line recently (New York’s 7 extension was just one stop, and its predicted ridership explicitly depends on future development). Since in general I do think cities should plan their rail extensions around where the busiest buses are, I want to talk about the situations that create a disjunction.
I mentioned in two past posts that rapid transit that surface transit and rapid transit alignments obey different rules, with respect to street geometry. In the more recent post, I used it to argue that tramway corridors should follow buses. In the older post, I argued that subways can take minor detours or go under narrower, slower streets to reach major destinations, for example Century City in Los Angeles, which is near the Wilshire corridor but not on it. However, the latter case isn’t quite what’s happening in any of the three examples here: Second Avenue Subway follows Second Avenue (though phases 1-2 diverge west to serve Times Square, which is important), and the Green Line Extension and Evergreen Line’s routes are both straighter than any bus in the area.
The situation in Boston and Vancouver is not that there’s an arterial bus that misses key destinations. Rather, it’s that the street network is inhospitable to buses. Boston is infamous for its cowpaths: only a few streets, such as Massachusetts Avenue, are wide and long enough to be reasonable corridors for arterial buses, and as a result, the bus network only really works as a subway feeder, with very high rail to bus ridership ratio by US standards. The corridors that do support busier buses – in the Greater Cambridge sector, those are the 77, 71, and 73 buses – are defined by the presence of continuous arterials more than by high latent travel demand.
Vancouver, of course, is nothing like Boston. Its bus grid is Jarrett Walker‘s standard example of an efficient, frequent bus grid. But this is only true in Vancouver proper, and in parts of Burnaby. In the other suburbs, either there’s an arterial street grid but not enough density for a good bus grid (Richmond, Surrey), or there’s no grid at all (Coquitlam). There’s a bus map of the Port Moody-Coquitlam area, with the 97-B line in bright orange and the 5-roundtrips-per-day West Coast Express commuter rail line in purple; the Evergreen Line will run straight from Port Moody to Coquitlam along an alignment parallel to the railroad, whereas the 97-B has to take a detour. Overall, I would class Coquitlam and Somerville together, as places where the street network is so bad for buses that rail extensions can plausibly get a large multiple of the ridership of existing buses.
Second Avenue Subway phase 1 partly belongs in this category, due to the difficulty of going from Second Avenue to Times Square by road, but high projected ridership on phase 3 suggests something else is at play as well. While First and Second Avenues are wide, straight throughfares, functioning as a consistent one-way pair, two factors serve to suppress bus ridership. First, Manhattan traffic is exceedingly slow. The MTA is proud of its select bus service treatments, which boosted speed on the M15 between 125th and Houston Streets to an average of about 10 km/h; in contrast, the Bx12 averages 13-14 km/h west of Pelham Bay Parkway. And second, the Lexington Avenue Line is 360 meters, so riders can walk a few minutes and get on the 6 train, which averages 22 km/h. The Lexington trains are overcrowded, but they’re still preferable to slow buses.
Now, the closeness to the Lexington trains can be waved away for the purposes of the principle of this post: I am interested in where preexisting transit ridership is not a good guide to future transit ridership, and in this example, we see the demand via high ridership on the 4, 5, and 6 trains. However, the issue of slow Manhattan traffic can be folded generally into the issue of circuitous street networks in Boston and Coquitlam.
It makes intuitive sense that the higher the bus-to-rail trip time ratio is, the higher the rail line’s ridership is relative to that of the bus it replaces. But what I’m saying here goes further: the two mechanisms at hand – a street network that lacks continuous arterials in the desired direction, and extensive traffic congestion – reduce the effectiveness of any surface solution. Is it possible to build tramways in the Vancouver suburbs? Yes. But in Coquitlam (and in Richmond and Surrey, for different reasons), they would be circuitous just like the buses. This also limits the ability of bus upgrades to solve transportation problems in such areas.
Now, what of New York? In theory, a bus or tram with absolute signal priority could run down the Manhattan avenues or the major outer-borough throughfares at high speed. But in practice, there is no such thing as absolute signal priority on city streets. It’s possible to speed up surface vehicles via signal priority, but they’ll still have to stop if cross-traffic blocks the intersection. In Paris, the tramways are not fast, averaging around 17-18 km/h, even though they have dedicated lanes and run on wide boulevards in the outer parts of the city and in the inner suburbs; in contrast, Metro Line 14, passing through city center, averages almost 40 km/h.
The implication here is that when a city develops its subway network, it should pay attention not just to where its busiest surface lines are, but also to which areas have intense activity but have suppressed surface ridership because the roads are slow or circuitous. These are often old city centers, built up before there were cars and even before there was heavy horse wagon traffic. Other times, they are general areas where the road network is not geared toward the desired direction of travel.
In cities without subways at all, there is a danger of overrelying on surface traffic, because such cities often have old cores with narrow streets, with intense pressure for auto-oriented urban renewal as they get richer. This is less common in the developed world, but nearly every developed-world city of note either has a rapid transit network already or is completely auto-oriented and has no areas where the road network is weak. Israel supplies several exceptions, since its transportation network is underdeveloped for how rich it is; in past posts I have already voiced my criticism of the decision to center the Tel Aviv Subway around wide roads rather than the older, often denser parts of the city.
In cities with subways, it’s rarely a systemic problem. That is, there’s rarely a specific type of neighborhood that can support higher rapid transit ridership than preexisting transit ridership would indicate. It depends on local factors – for example, in Somerville, the railroads are oriented toward Downtown Boston, but the streets are not, nor are they oriented toward good transfer points to the subway. This means transit planners need to carefully look at the road network for gaps in the web of fast arterials, and consider whether those gaps justify transit investment, as the GLX and Evergreen Line do.
Small, dense developed countries should electrify their entire national rail networks. Usually, railroads think in terms of electrifying lines, but this hides the systemwide benefits of transitioning the entire network to run under electricity. I have previously written about this in the context of regionally funded commuter rail systems, as have Paul Druce and Clem Tillier. But some countries are so small and dense that the analysis for a single large metro area holds nationwide as well.
In this post I am going to focus on Israel, which is completely unelectrified, but also foray into mostly-electrified Belgium and the Netherlands, and currently-electrifying Denmark. Switzerland has already completed electrification; it is less dense than all of those countries except Denmark, but has cheap hydro power, which makes it cheaper to run trains under electricity, and key mainlines through mountainous terrain, where electrification is a major performance booster.
First, let us recall the performance benefits of electrification in flat terrain. The major rolling stock manufacturers sell DMUs with top speeds of 120-140 km/h, and EMUs with top speeds of 140-200 km/h; faster trains are generally more expensive, and with a few exceptions not of much use outside dedicated high-speed rail lines. The difference in acceleration performance is large: when the top speed is 100 km/h, an EMU such as the FLIRT takes less than 30 seconds to accelerate from standstill to top speed, corresponding to an acceleration time penalty of about 14 seconds, whereas the Stadler GTW DMU has a penalty of about 28 seconds (see data on PDF-p. 43); the GTW EMU version, a less powerful train than the FLIRT, loses 19 seconds. DMUs are also less comfortable than EMUs, because the diesel engines are right under passengers’ feet; longer-distance lines almost never use them, and instead use diesel locomotives, which accelerate even more slowly.
Because of this large difference in acceleration performance, electrification delivers the greatest performance benefits on lines with closely-spaced stops and high traffic. These are usually commuter rail lines rather than intercity lines. For example, suppose the top speed is 130 km/h, the stop spacing is 3 km, station dwell times are 30 seconds, and schedules are padded 7%. The FLIRT’s acceleration penalty is about 19 seconds, that of the diesel GTW (to 125 km/h) is 43 seconds; the deceleration penalties are both a bit lower than the acceleration penalties, but not too much lower, to avoid overheating. An EMU will average 68 km/h, a DMU 52 km/h. Independently of comparative energy and maintenance costs, this represents a 23% cut in the rolling stock requirement and in the on-board labor cost, and a larger cut in the required subsidy thanks to higher ridership. In contrast, if the stop spacing is 50 km, the difference in speed shrinks to 116 km/h vs. 113 km/h. Even if the EMU can do 160 km/h, its average speed is 140 km/h, still a smaller percentage difference than in the case of commuter rail, while the cost of providing this higher average speed is larger because tracks need to be upgraded to a higher top speed.
In small countries, short stop spacing is the normal state of affairs. In Israel, few segments of track have stops spaced more than 10 km apart, and those are mostly on the under-construction high-speed line from Tel Aviv to Jerusalem, which is planned to host 200 km/h electric trains. In the Tel Aviv and Haifa metro areas, stop spacing in the 3-4 km range is normal. Even intercity trains make all stops within Tel Aviv and Haifa proper, skipping the stations between those two cities. There are no major cities north of Haifa, only suburbs and small cities, and thus making many stops in and north of Haifa is justified for intercity trains – there aren’t many through-passengers who are being inconvenienced. South of Tel Aviv there are some moderate-size cities (as well as Jerusalem, but the legacy rail line to it is so curvy that the train from Tel Aviv takes twice as long as the bus), but because of high traffic, all trains make all four Tel Aviv stops.
With the exception of Belgium, all four countries under discussion also have dominant primate city regions, with about 40% of their respective national population; those city regions have dense rail networks, which are electrified in all countries except Israel. Denmark runs the Copenhagen commuter lines as a separate S-tog from the rest of the network, but in the Netherlands, Israel, and Belgium, there is no sharp difference. The result is that a large fraction of the overall rail network is urban commuter rail, which should be electrified, while additional chunks are regional rail with enough frequency to justify electrification even without a large city in the center.
Moreover, the service pattern makes it hard to electrify just a few lines in isolation, even if they’re the busiest. Regional rail networks frequently employ through-running. In small countries, this is common for the entire rail network, for different reasons: in Israel, the route through Tel Aviv is a new line from 20 years ago, without many platform tracks for terminating trains, whereas in the Netherlands and Belgium it’s the result of a highly nonlinear population distribution, which favors a mesh of lines, such that busy routes share tracks extensively with less busy ones. Compare these population distributions with that of the Northeastern US, where there is clear division into a trunk from Washington to Boston and branches heading inland.
Finally, these are all small countries. This is why I am not including South Korea in this proposal, even though it is denser, more mountainous, and more primate city-centric than all countries under discussion: South Korea is large enough that it’s plausible to run the Seoul-area commuter rail as an isolated electrified system, keeping the remainder of the legacy network unelectrified, with several maintenance shops for diesel trains around the country. In contrast, the unelectrified portion of the Dutch rail network consists of isolated branch lines, making it less economic to keep operating diesel trains. Israel has no electrification at all, but if it electrifies the Tel Aviv and Haifa commuter trains, the remainder of the network will be disjointed, requiring inefficient solutions such as considerable deadheading, or regular runs of diesel trains under long stretches of catenary.
One example I keep harping on, which I got from The LIRR Today before its blackout, is the LIRR’s diesel runs. The LIRR is almost completely electrified, and its diesel branches see little service, especially at the easternmost end of Long Island. Between this and work rules that separate diesel and electric train crew, the crew on one of the diesel trains work 2.5 hours per workday, running a train once in one direction and deadheading the way back; this and the bespoke nature of diesel trains on the LIRR lead to high operating costs.
The situations in the countries in question are not as comical as on the LIRR, but there are bound to be inefficiencies in Belgium and the Netherlands, and soon to be Denmark, which is electrifying its main lines, which together with the S-tog are a majority of its network. In Israel, the situation is the worst, since its rail network is even smaller: 1,100 km, compared with 2,600 km in Denmark, 3,600 in Belgium, and 2,900 in the Netherlands; this means that a partially electrified situation involves even smaller train orders and higher operating costs, while an entirely unelectrified network involves poor service in the urban areas.
Israel also has no rail links with any of its neighbors, nor any plans to construct any. This means that its branch lines are truly isolated, unlike those of the Netherlands, Belgium, and Denmark, which sometimes connect to other unelectrified lines in neighboring countries.
The way out of high diesel operating costs is to spend the money on completing electrification. As the example of Denmark shows, the costs are not outrageous: about $1.1 million per kilometer (I do not know whether track- or route-km, but I believe this is track-km). In the case of Israel, whose rail network is almost entirely single-track, this is not much more than $1 billion either way; to put things in perspective, the projected cost of the first Tel Aviv subway line is now up to $4.2 billion, while the Ministry of Transportation’s overall budget is $3 billion per year (PDF-p. 10), mostly spent on roads, in a country with only 300 cars per 1,000 people.
All-diesel railroads resist electrifying their busiest lines because they prefer to be able to let every train substitute for any train, and, for smaller operations, maintain all trains in one yard. For the same reason, small railroads with high traffic, such as the national railroads of dense countries, should instead go all-electric, in order to retain the benefits of interchangeable trains and maintenance facilities while also capturing the benefits of electrification. It’s not terribly relevant to the countries I’ve recently lived in, but for the same reason Switzerland fully electrified, similar small, dense countries should do the same.
I have been thinking of alternatives to the current plan for a Tel Aviv Subway for several years now; last year I expounded on some principles for a better plan. As I mentioned last year, Tel Aviv’s subway system should be shaped roughly like the letter E, with a single north-south spine paralleling the rail mainline and three east-west lines intersecting the mainline at the city’s three main train stations. Today I would like to give more details about this system, with special focus on commuter rail. While thinking of how to create an optimal system serving the region’s secondary centers, I came upon an important principle used on the Paris RER and the Zurich S-Bahn, which past posts (including my own) on the subject downplayed in favor of city-center tunnels: namely, it is often correct to deviate from legacy alignments for a few kilometers in order to better serve a secondary center, even if it requires some greenfield tunneling.
Before I go on, I will note that this plan is intended to be politically neutral, in the sense of serving the dense primary and secondary urban centers of Gush Dan regardless of ethnicity, and with only weak regard for income. In my view, if there are anti-government riots in response to police shooting of a young minority, this is not a reason to deny service to the area; on the contrary, denial of social services is what creates the social alienation that contributes to rioting. But more than this, this plan assumes everyone travels to the same destinations, a reasonable approximation in a country with the level of social integration of the US or a monolingual European country, but a problematic one in Israel.
About 18% of Israel’s population is Arab, and another 12% is ultra-Orthodox; both groups are highly segregated, and have their own job centers. On 972Mag’s Hebrew-language sister site, Noam Sheizaf reports that MK Hanin Zoabi (the Knesset’s sole Arab woman), best-known for her incendiary rhetoric against the IDF, criticized the state’s emphasis on developing fast transportation to Tel Aviv on the grounds that Arabs, especially Arab women, typically work close to home. Incomes are much lower than those of mainline Jews as well: I have no ultra-Orthodox data, but making mild assumptions on income distribution within each decile from Central Bureau of Statistics data, per capita income from work is about $6,000 per year for Arabs, a bit higher than Romania excluding Bucharest, and $16,500 for Jews, a bit higher than Greece or Southern Italy. The best American analogy I can think of is the development of dedicated buses for Chinese immigrants in New York City proper and ultra-Orthodox Jews in the New York area, as both groups are very poor and have different centers bypassing Midtown and Lower Manhattan.
With this deliberate decision to ignore ethnic composition in mind, my plan is to build an E-shaped subway system, with the E’s southern leg turning north at its western end to provide a second north-south line in Central Tel Aviv. Here is a link to the map I currently think works the best. The brown lines are an electrified commuter rail system running at very high frequency between Tel Aviv HaHagana and Exhibition Center (currently called Tel Aviv University, though the station is quite far from the center of campus). Observe that the lines deviate from the current network in a few places:
* The circumferential service running along the Eastern Line loops to serve Elad better.
* There is a new branch into Kafr Qassem, passing much closer to Rosh HaAyin’s built-up area than the current Rosh HaAyin North station does.
* The Kfar Saba branch is completely redone. There are plans to connect it to the Coastal Railway concurrently with building a freeway along the same alignment, going due west from its current terminus alongside Route 531. The freeway should be scrapped – Israel is building too many of them, and insists of bundling every transit project with a freeway (even the currently proposed Red Line is planned to come together with a freeway tunnel through an alignment near Jaffa Road in South Tel Aviv, forcing the line to go deeper and raising its costs). Moreover, the connection west of Kfar Saba should be more direct. Conversely, east of Kfar Saba there is a right-of-way that can be used to send trains up to Tira, and perhaps farther into the Triangle, into Tayibe or Qalansawe.
* There is a new branch to Glilot and Herzliya Pituah, an edge city located a bit too far from the Herzliya train station to be a comfortable walk, especially along the wide, pedestrian-hostile access road.
* The line enters Netanya along a new alignment, with a short tunnel; the current Netanya station is at the edge of the built-up area.
* There is a reactivated branch serving Tsrifin.
* The route through Rishon LeZion avoids the current plans to connect Rishonim Station (Kiryat Simha on my map, to avoid confusing with Ramat HaSharon Rishonim) to the Ashdod Branch via Route 431, avoiding the Rishon LeZion built-up area. Rishon is a sprawling suburb, but has more than 200,000 people, and secondary centers; it is better to spend a bit more money, tunneling under the center of the city and going above-ground to its west to serve the College of Management Academic Studies, Israel’s largest independent (i.e. non-university) college.
These short tunnels are in line with construction in European cities: the Paris RER’s centerpiece is the connecting tunnels in central Paris, but as seen on this map, which includes chronology, the Charles-de-Gaulle branch opened in 1976, shortly before the RER B it connects to, and the Disneyland branch opened in 1977, concurrently with the RER A. The Zurich S-Bahn includes short greenfield tunnels to access the airport from both directions. The Stockholm commuter rail system includes a tunneled loop serving Arlanda, which was built for the Arlanda Express and then extended and used by the regular commuter trains. Usually these new tunnels serve airports or other new centers such as Disneyland, since the old secondary centers already have legacy lines, but in Israel, most towns’ train stations are located at the edge of the built-up area rather than in the center, and in the larger secondary cities, this justifies some additional tunneling.
On the same principle, the Jabotinsky subway line, which is otherwise elevated outside the Tel Aviv core, tunnels to reach central Petah Tikva, in lieu of the current plan to skirt the center of the city and go in tram mode to Petah Tikva Central Bus Station.
I expect most ridership, and by far most of the cost, to come from the subway lines, colored red, green, blue, and yellow; I call them subways, but out of the system’s 60 km, 27 are above ground and only 33 are underground, mainly in Tel Aviv proper and in the parts of Ramat Gan and Givatayim that do not have wide roads for a right-of-way. I chose names for political reasons: the north-south line is called the Jaffa Line since it passes through Jaffa, a low-income left-wing Arab area; the northern leg of the E is called the Jabotinsky Line since it runs largely along streets named after Zeev Jabotinsky, founder of Revisionist (right-wing) Zionism; the central leg of the E is called HaShalom Line since it intersects the mainline at HaShalom train station, and the peace process (shalom in Hebrew) is a cornerstone of the Zionist left; and the southern leg of the E is called HaTikva Line since it passes through HaTikva, a low-income right-wing Mizrahi neighborhood. I tried to steer clear of politics in the route choice: only the choice of names, constrained by the need to refer to features of the lines, is political.
In the remainder of the post, I will deal with possible objections to the proposal, and with various doubts and drawbacks.
1. Probably the biggest objection I expect is that the system skirts the proposed Tel Aviv CBD, which is District 6 on this map. Unlike the current plan, there are no tunnels under Namir Road, but rather the tunnels are farther west, in the city’s traditional center. This is deliberate. I do not have bus traffic data, but I do have frequency data for the most frequent buses, expressed in daily departures in both directions. It is in Hebrew on the Israeli Bike-to-Bus Rider blog; the key is that a gold medal denotes at least 4 buses per hour, a bronze one denotes at least 3, a silver one denotes at least 3 and at least 4 at and on the shoulders of the peak, and a V on the left column denotes at least 6 at rush hour. The bus route numbers are on the second column from the right. See also this frequent bus map to match route numbers to streets.
While I criticized the use of bus corridors for subway planning last year, noting that buses serve the wider Jerusalem Boulevard through Jaffa and not the narrower but more centrally-located Yefet Street, the map provides a rough guide to which regions and which directions of travel have the most demand. North-south travel along Ben Yehuda, Dizengoff, and Ibn Gabirol Streets and Namir Road is very popular. Ben Yehuda’s routes 4, 104, and 204, which HaTikva Line roughly parallels, have 642 buses per day. Dizengoff’s routes 5, 39, 72, 129, 172, and 239 have 1,071. Route 9, which runs along Ben Yehuda and Dizengoff in a one-way pair, has 162. Ibn Gabirol’s routes 24, 25, 125, 126, 189, and 289 have 986. And Namir Road’s routes 1, 40, 42, 51, 60, 71, 160, 171, 240, and 271 have 1,726. Despite the large number of buses on Namir, these buses closely parallel mainline rail, and moreover, there are 65% more buses on Ibn Gabirol and points west.
2. My plan ignores many active plans made by the state. This is on purpose: until such projects as combined freeway-rail lines are built, they should be opposed, since the road construction will ensure connectivity by road will be faster than by rail, frustrating any attempt to maintain a high public transit mode share. To my understanding, the most expensive portions of the planned subway, namely the underground parts, have not been built, and on the contrary there are constant schedule and budget slips; the current timetable calls for the completion of the Red Line in 2023, and the budget has slipped from 10.7 to 14 to 17 billion shekels; this is $200 million/km, accounting for PPP but not future inflation (if Israel holds to 2% inflation, it will be about $180 million/km), for a line that’s only 43% underground.
3. Four-tracking the mainline rail route through Tel Aviv is going to be expensive, since it requires building over or rerouting the Ayalon River. In the long run, rail growth makes such construction necessary: Israel’s economic geography forces all travel between the north and the south to go through or right next to Tel Aviv, which means potential travel demand is higher than through Stockholm, which is currently four-tracking its main route through T-Centralen to provide for both additional commuter rail and intercity rail service.
In the short run, there are two ways to cut initial costs. First, it may be the case that there is room for four tracks along the Ayalon right-of-way, as long as only two are served by station platforms. If that is true, then HaShalom should be reconfigured as a local station, with two nonstop tracks, while all trains should continue to stop at Tel Aviv Center and HaHagana, both of which already have more than 4 tracks. While HaShalom is Israel’s second busiest train station (see file here, shared by a forum member back in 2008: the leftmost column is total daily entries and exits), high-frequency local commuter rail service connecting it with Tel Aviv Center and HaHagana is an acceptable substitute if it saves a lot of money.
And second, Israel Railways runs very inefficiently, partly because of single-tracking and partly because of the use of slow-accelerating diesel locomotives. Peak traffic on the two-track mainline, excluding the third track (which is run as a captive single-track commuter line), is still in the single digits of trains per hour. While my plan calls for 10-minute peak frequencies on each of 5 branches, I believe that for a long while, several branches could make do with 20 minutes; with high-capacity signaling, and the use of the third track for emergencies if a train is late, 30 trains per hour are possible, permitting space for commuter trains as well as the four hourly intercity trains to Haifa, two to Beer Sheva, and future trains to Jerusalem.
4. Too much service to the north. The way the map is presented, without extra proposed extensions, the best-served part is District 6, which has almost no residential population: counting transfer stations twice and jurisdiction-boundary stations as belonging half to each jurisdiction, it has 1.5 stations for 4,600 residents, or 1 per 3,000. But the second best is District 3, the Old North, and even Herzliya is better-served than District 8, South Tel Aviv. It’s an unfortunate fact that Herzliya’s train station is located on a pedestrian-hostile road, between the two centers of Herzliya and Herzliya Pituah and beyond walking distance to both, requiring considerable additional construction; but it’s also possible to either eliminate the Herzliya Pituah commuter rail branch or cut the Jaffa Line to KKL Junction. The Old North needs this much service, because of the high demand for bus service along both Dizengoff/Ben Yehuda and Ibn Gabirol, as well as the presence of several major retail and entertainment centers, such as the Port, the Marina and waterfront hotels, and Dizengoff Center, making the neighborhood more than just residential.
5. Not enough service to the south, especially Holon. The official plan calls for building a second line going north-south from Tel Aviv University to Holon and Rishon LeZion, giving two north-south branches to the south (including the initial one to Bat Yam) versus one in my plan. I admit that the indirect service to Holon is problematic, but counter that the city is substantially less dense than Bat Yam, and moreover the east-west orientation of the Jaffa Line connects the two cities while giving Holon a transfer to a direct mainline rail connection to Tel Aviv. Rishon LeZion is completely cut from my subway plan, but gains a centrally-located commuter rail station.
South Tel Aviv has relatively little service, too, since the Jaffa Line and HaTikva Line have stops just outside it. The alternative I proposed within the map file, in which HaShalom Line is extended two more stops to Old Jaffa while the Jaffa Line is rerouted along the more southeasterly Shalma Road alignment, provides several more South Tel Aviv stations and makes Central Bus Station the Jaffa/HaTikva transfer point, at the cost of a detour that lengthens end-to-end trips as well as about 3 km of additional tunneling. In either case, the center of South Tel Aviv today is close enough to Central Bus Station to be serviceable, even if it’s only by one line rather than two.
6. Tight timed transfers. Unlike the simply-connected lines branching to the north, the lines to the south have multiple mergers, to be dealt with using timed transfers at Lod and Lod Junction. The plan is, using a 20-minute clockface schedule, to have Airport Branch trains leave 4 minutes before mainline Lod trains, be slowed down by the airport detour and the extra stops, and have a timed transfer with the Eastern Line at Lod Junction, which then has a timed transfer at Lod. This corresponds to a 4-minute slowdown as planned, but requires two successive transfers. I do not know to what extent this is robust, although given relatively low frequency per branch, I do not think it’s a trouble on a railroad with reliable trains and level boarding. Israel’s current diesel rolling stock is unreliable, but this can be fixed with EMUs, and there’s already level boarding.
7. Station locations. I tried keeping station spacing to one per kilometer, but ended up finding more good locations, so station spacing is slightly narrower. More fundamentally, at several spots, mainly east of Ayalon, I chose station locations based on destinations rather than street intersections. The tradeoff is that the destinations can provide better waiting spots than an intersection of two wide roads built for high car speeds, and by definition have something within walking distance, but street intersections make it easier to run connecting buses.
8. Quibbles on termini. These I am happy to be convinced about, including the eastern termini of HaTikva Line (on Twitter, Moshe Schorr proposes avoiding Kiryat Ono, and instead swerving southeast to serve Or Yehuda and Yehud), the southern terminus in Ashdod (it is possible for trains to enter the city on viaducts and serve it more centrally), and extensions or cutbacks to lines already mentioned.
9. Quibbles on routes. As with the termini, I am happy to make changes. These include the route through Ramat Aviv (the current map provides a stop on the south side of the Tel Aviv University campus, but it’s possible to instead take two sharp turns and serve Ramat Aviv Mall), and the routes of HaShalom and HaTikva lines through Ramat Gan and Givatayim, which could both be moved south. There are no compelling destinations west of the eastern anchors at Bar Ilan and the Bakum/Kiryat Ono and east of the neighborhoods abutting Ayalon such as HaTikva, which makes the routes more flexible.
The first two objections are the most fundamental, and the ones I feel the most strongly I am right again. The others are smaller changes, in descending order of importance, and do not conflict with the concept of an E-shaped rapid transit system supporting a single frequent S-Bahn spine.
