People I respect are asking me about alternative routes for intercity trains into Boston. So let me explain why everything going into the city from points south should run to South Station via Providence and not via alternative inland routes such as Worcester or a new carved-up route via Woonsocket.
As an explanation, here is a map of the region’s commuter rail network; additional stations we’re proposing for regional rail are in turquoise, and new line segments are dashed.
Observe that the Providence Line, the route currently used by all intercity trains except the daily Lake Shore Limited, is pretty straight – most of it is good for 300+ km/h as far as track geometry goes. The Canton Viaduct near that Canton Junction station is a 1,746 meter radius curve, good for 237 km/h with active suspension or 216 km/h with the best non-tilting European practice. This straightness continues into Rhode Island, separated by a handful of curves that are to some extent fixable through Pawtucket. The fastest segment of the Acela train today is there, in Massachusetts and Rhode Island.
The Worcester Line is visibly a lot curvier. Only two segments allow 160 km/h running in our regional rail schedules, around Westborough and immediately west of Grafton. This is why, ignoring intercity rail, our timetables have Boston-Providence trains taking 47 minutes where Boston-Worcester express trains take 45 minutes with 4 fewer stops or 57 minutes with 5 more, over the same route length. And the higher the necessary top speed, the larger the trip time mismatch is due to curves.
Going around the curves of the Worcester Line is possible, if high-speed rail gets a bypass next to I-90. However, this introduces three problems:
- More construction is needed, on the order of 210 km between Auburndale and New Haven compared with only 120 between Kingston and New Haven.
- Bypass tracks can’t serve the built-up area of Worcester, since I-90 passes well to its south. A peripheral station is possible but requires an extension of the commuter rail network to work well. Springfield and Hartford are both easy to serve at city center, but if only those two centers are servable, this throws away the advantage of the inland route over Providence in connecting to more medium-size intermediate cities.
- The two-track section through Newton remains the stuff of nightmares. There is no room to widen the right-of-way, and yet it is a buys section of the line, where it is barely possible to fit express regional rail alongside local trains, let alone intercity trains. Fast intercity trains would require a long tunnel, or demolition of two freeway lanes.
There’s the occasional plan to run intercity rail via the Worcester Line anyway. This is usually justified on grounds of resiliency (i.e. building too much infrastructure and running it unreliably), or price discrimination (charging less for lower-speed, higher-cost trains), or sheer crayoning (a stop in Springfield, without any integration with the rest of the system). All of these justifications are excuses; regional trains connecting Boston with Springfield and Springfield with New Haven are great, but the intercity corridor should, at all levels of investment, remain the Northeast Corridor, via Providence.
The issue is that, even without high-speed rail, the capacity and high track quality are on Providence. Then, as investment levels increase, it’s always easier to upgrade that route. The 120 km of high-speed bypass between New Haven and Kingston cost around $3-3.5 billion at latter-day European costs, save around 25 minutes relative to best practice, and open the door to more frequent regional service between New Haven and Kingston on the legacy Shore Line alongside high-speed intercity rail on the bypass. This is organizationally easy spending – not much coordination is required with other railroads, unlike the situation between New Haven and Wilmington with continuous track sharing with commuter lines.
If more capacity is required, adding strategic bypasses to the Providence Line is organizationally on the easy side for intercity-commuter rail track sharing (the Boston network is a simple diagram without too much weird branching). There’s a bypass at Attleboro today; without further bypasses, intercity trains can do Boston-Attleboro in 11 fewer minutes than regional trains if both classes run every 15 minutes, which work out to 25 minutes per our schedule and around 32 between Boston and Providence. To run intercity trains faster, in around 22 minutes, a second bypass is needed, in the Route 128-Readville area, but that is constructible at limited cost. If trains are desired more than very 15 minutes, then a) further four-tracking is feasible, and b) an intercity railroad that fills a full-length train every 15 minutes prints money and can afford to invest more.
This system of investment doesn’t work via the inland route. It’s too curvy, and the bypasses required to make it work are longer and more complex to build due to the hilly terrain. Then there’s the world-of-pain segment through Newton; in contrast, the New Haven-Kingston bypass can be built zero-tunnel. But that’s fine! The Northeast Corridor’s plenty upgradable, the inland route is bad for long-distance traffic (again, regional traffic is fine) but thankfully unnecessary.
I stream on Twitch (almost) every week on Saturdays – the topic starting now is fare systems. Two weeks ago, I streamed about the topic of how to mix high-speed rail and regional rail together, and unfortunately there were technical problems that wrecked the recording and therefore I did not upload the video to YouTube as I usually do. Instead, I’d like to write down how to do this. The most obvious use case for such a blending is the Northeast Corridor, but there are others.
The good news is that good high-speed rail and good legacy rail are complements, rather than competing priorities. They look like competing priorities because, as a matter of national tradition of intercity rail, Japan and France are bad at low-speed rail outside the largest cities (and China is bad even in the largest cities) and Germany is bad at high-speed rail, so it looks like one or the other. But in reality, a strong high-speed rail network means that distinguished nodes with high-speed rail stations become natural points of convergence of the rail network, and those can then be set up as low-speed rail connection nodes.
Where there is more conflict is on two-track lines with demand for both regional and intercity rail. Scheduling trains of different speeds on the same pair of tracks is dicey, but still possible given commitment to integration of schedule, rolling stock, and timetable. The compromises required are smaller than the cost of fully four-tracking a line that does not need so much capacity.
Whenever a high-speed line runs separately from a legacy line, they are complements. This occurs on four-track lines, on lines with separate high-speed tracks running parallel to the legacy route, and at junctions where the legacy lines serve different directions or destinations. In all cases, network effects provide complementarity.
As a toy model, let’s look at Providence Station – but not at the issue of shared track on the Northeast Corridor. Providence has a rail link not just along the Northeast Corridor but also to the northwest, to Woonsocket, with light track sharing with the mainline. Providence-Woonsocket is 25 km, which is well within S-Bahn range in a larger city, but Providence is small enough that this needs to be thought of as scheduled regional rail. A Providence-Woonsocket regional link is stronger in the presence of high-speed rail, because then Woonsocket residents can commute to Boston with a change in Providence, and travel to New York in around 2 hours also with a change in Providence.
More New England examples can be found with Northeast Corridor tie-ins – see this post, with map reproduced below:
The map hides the most important complement: New Haven-Hartford-Springfield is a low-speed intercity line, and the initial implementation of high-speed rail on the Northeast Corridor should leave it as such, with high-speed upgrades later. This is likely also the case for Boston-Springfield – the only reason it might be worthwhile going straight from nothing to high-speed rail is if negotiations with freight track owner CSX get too difficult or if for another reason Massachusetts can’t electrify the tracks at reasonable cost and run fast regional trains.
There’s also complementarity with lines that are parallel to the Northeast Corridor, like the current route east of New Haven, which the route depicted in the map bypasses. This route serves Southeast Connecticut communities like Old Saybrook and can efficiently ferry passengers to New Haven for onward connections.
In all of these cases, there is something special: Woonsocket-Boston is a semireasonable commute, New London connects to the Mohegan Sun casino complex, New Haven-Hartford and Boston-Springfield are strong intercity corridors by themselves, Cape Cod is a weekend getaway destination. That’s fine. Passenger rail is not a commodity – something special almost always comes up.
But in all cases, network effects mean that the intercity line makes the regional lines stronger and vice versa. The relative strength of these two effects varies; in the Northeast, the intercity line is dominant because New York is big and off-mainline destinations like Woonsocket and Mohegan are not. But the complementarity is always there. The upshot is that in an environment with a strong regional low-speed network and not much high-speed rail, like Germany, introducing high-speed rail makes the legacy network stronger; in one that is the opposite, like France, introducing a regional takt converging on a city center TGV station would likewise strengthen the network.
Competition for track space
Blending high- and low-speed rail gets more complicated if they need to use the same tracks. Sometimes, only two tracks are available for trains of mixed speeds.
In that case, there are three ways to reduce conflict:
- Shorten the mixed segment
- Speed up the slow trains
- Slow down the fast trains
Shortening the mixed segment means choosing a route that reduces conflict. Sometimes, the conflict comes pre-shortened: if many lines converge on the same city center approach, then there is a short shared segment, which introduces route planning headaches but not big ones. In other cases, there may be a choice:
- In Boston, the Franklin Line can enter city center via the Northeast Corridor (locally called Southwest Corridor) or via the Fairmount Line; the choice between the two routes is close based on purely regional considerations, but the presence of high-speed rail tilts it toward Fairmount, to clear space for intercity trains.
- In New York, there are two routes from New Rochelle to Manhattan. Most commuter trains should use the route intercity trains don’t, which is the Grand Central route; the only commuter trains running on Penn Station Access should be local ones providing service in the Bronx.
- In the Bay Area, high-speed rail can center from the south via Pacheco Pass or from the east via Altamont Pass. The point made by Clem Tillier and Richard Mlynarik is that Pacheco Pass involves 80 km of track sharing compared with only 42 km for Altamont and therefore it requires more four-tracking at higher cost.
Speeding up the slow trains means investing in speed upgrades for them. This includes electrification where it’s absent: Boston-Providence currently takes 1:10 and could take 0:47 with electrification, high platforms, and 21st-century equipment, which compares with a present-day Amtrak schedule of 0:35 without padding and 0:45 with. Today, mixing 1:10 and 0:35 requires holding trains for an overtake at Attleboro, where four tracks are already present, even though the frequency is worse than hourly. In a high-speed rail future, 0:47 and 0:22 can mix with two overtakes every 15 minutes, since the speed difference is reduced even with the increase in intercity rail speed – and I will defend the 10-year-old timetable in the link.
If overtakes are present, then it’s desirable to decrease the speed difference on shared segments but then increase it during the overtake: ideally the speed difference on an overtake is such that the fast train goes from being just behind the slow train to just ahead of it. If the overtake is a single station, this means holding the slow train. But if the overtake is a short bypass of a slow segment, this means adding stops to the slow train to slow it down even further, to facilitate the overtake.
A good example of this principle is at the New York/Connecticut border, one of the slowest segments of the Northeast Corridor today. A bypass along I-95 is desirable, even at a speed of 200-230 km/h, because the legacy line is too curvy there. This bypass should also function as an overtake between intercity trains and express commuter trains, on a line that today has four tracks and three speed classes (those two and local commuter trains). To facilitate the overtake, the slow trains (that is, the express commuter trains – the locals run on separate track throughout) should be slowed further by being made to make more stops, and thus all Metro-North trains, even the express trains, should stop at Greenwich and perhaps also Port Chester. The choice of these stops is deliberate: Greenwich is one of the busiest stops on the line, especially for reverse-commuters; Port Chester does not have as many jobs nearby but has a historic town center that could see more traffic.
Slowing down the intercity trains is also a possibility. But it should not be seen as the default, only as one of three options. Speed deterioration coming from such blending in a serious problem, and is one reason why the compromises made for California High-Speed Rail are slowing down the trip time from the originally promised 2:40 for Los Angeles-San Francisco to 3:15 according to one of the planners working on the project who spoke to me about it privately.
Modernizing Rail 2021 just happened. Here’s a recording of the Q&A portion (i.e. most) of the keynote, uploaded to YouTube.
As more people send in materials, I’ll upload more. For now, here are the slides I’ve gotten:
- Grecia White’s master’s thesis on gendered perceptions of safety at bus stops.
- Robert Hale’s presentation on New York-New Haven trains, speed, and track maintenance productivity.
- Michael Cornfield’s intro to integrated service planning as done in Central Europe, pitched to Southern California.
- RailPAC’s Paul Dyson’s presentation on Southern California (unfortunately running against Michael Cornfield’s despite the synergy), with supplementary materials by RailPAC’s Brian Yanity including a long article on the subject and two short letters.
- Elif Ensari’s presentation of the Istanbul case for the Transit Costs Project, with full report to be released soon.
A bunch of us tweeted the talks using the hashtag #ModernRail2021, including some that were not recorded.
The bipartisan infrastructure framework (BIF) just passed the Senate by a large margin, with money for both roads and public transportation. Unlike the 2009 Obama stimulus, the BIF has plenty of money for high-speed rail – not just $8 billion as in the 2009 bill, but a total of $66 billion to be spent on mainline rail. The Northeast Corridor program gets $24 billion out of this $66 billion in a dedicated program and another $6 billion out of another program within this bucket dedicated to Amtrak. This is $30 billion, which should be more than enough for high-speed rail on the Northeast Corridor. Together with other buckets for other parts of the US, it can even build some non-Northeastern lines, for example serving Chicago or Los Angeles.
I say should because the current plans are to waste the money. But better things are possible, so at the Transit Costs Project, we’re planning to embark on a project to write a report on how to do this better. The construction cost report will be done in early 2022, but we can overlap to some extent. A one-year program, to debut in early 2023, will include a Northeast Corridor proposal; a two-year one will also include tie-ins and starter lines elsewhere, such as Chicago-Cleveland/Detroit or Los Angeles-San Diego.
But for this, we need funding. We’re a good deal of the way there, I think around two-thirds for the two-year option – and this isn’t quite enough for the one-year option, some of the money needs to be matched. This is not the same as my Patreon in either scale (the difference is more than an order of magnitude) or scope (my Patreon funds the blog and vlog, which are way more general); if you know grants for such projects, please let us know, we can send a fuller proposal.
What’s the project’s scope?
Lots and lots of analysis, for one, like what we’re doing for subways. Intriguingly, high-cost countries for high-speed rail tend to also have high subway costs and vice versa, and this remains true even as it is easier to explain high-speed rail costs in terms of unnecessary scope and leakage. But this is not the dominant part of the project – rather, we are going to be synthetic and make a proposal. We’re not committing to an investment figure; my guess is that in 2021 dollars it should be around $15 billion to cut Northeast Corridor trip times to about 1:45 on each of New York-Boston and New York-Washington, but some variation is possible in either direction.
If there’s $30 billion for the Northeast Corridor, and high-speed rail is doable for half that, then the other half should be spent on tie-ins, for example improving regional rail in all four major metropolitan areas. Naturally, this should only include useful spending for rail operations and connections, but the Northeast doesn’t lack for those; New York can spend $17 billion on new tunnels and that’s at the per-km cost of Citybanan, one of the cheaper city center regional rail projects in our database.
We are happy to announce that on Sunday the 29th of August we will hold this year’s Modernizing Rail conference, on the heels of the success last year.
Please register using this form. And please give details on what you’d like to see, and if you’re willing to lead sessions – the schedule of the breakout sessions is still up in the air depending on popular demand. Even the number of breakouts depends on how many registrants we get, compared with the about 200 we had last year. Perhaps the news of the infrastructure bill will tilt the demand toward more political sessions regarding how to ensure what is built is good and less toward technical best practices.
Our keynote is certainly political: Rep. Seth Moulton (D-MA), who represents the northern suburbs of Boston (6th district) and for years has been pushing the North-South Rail Link. He will give brief remarks at 16:00 Eastern time, or 22:00 Central Europe Summer Time, to be followed by a Q&A; if you have a question that you’d like to hear an answer to, you can mention it in the registration form, or email the organizing committee at firstname.lastname@example.org. We will be taking questions throughout the conference, which will start 11:00 Eastern, so if your questions depend on what you hear at the breakouts, you’re in luck.
And yet there’s a problem of comparable size when discussing infrastructure waste, which, lacking any better term for it, I am going to call leakage. The definition of leakage is any project that is bundled into an infrastructure package that is not useful to the project under discussion and is not costed together with it. A package, in turn, is any program that considers multiple projects together, such as a stimulus bill, a regular transport investment budget, or a referendum. The motivation for the term leakage is that money deeded to megaprojects leaks to unrelated or semi-related priorities. This often occurs for political reasons but apolitical examples exist as well.
Before going over some examples, I want to clarify that the distinction between leakage and high costs is not ironclad. Sometimes, high costs come from bundled projects that are costed together with the project at hand; in the US they’re called betterments, for example the $100 million 3 km bike lane called the Somerville Community Path for the first, aborted iteration of the Green Line Extension in Boston. This blur is endemic to general improvement projects, such as rail electrification, and also to Northeast Corridor high-speed rail plans, but elsewhere, the distinction is clearer.
Finally, while normally I focus on construction costs for public transport, leakage is a big problem in the United States for highway investment, for political reasons. As I will explain below, I believe that nearly all highway investment in the US is waste thanks to leakage, even ignoring the elevated costs of urban road tunnels.
State of good repair
A month ago, I uploaded a video about the state of good repair grift in the United States. The grift is that SOGR is maintenance spending funded out of other people’s money – namely, a multiyear capital budget – and therefore the agency can spend it with little public oversight. The construction of an expansion may be overly expensive, but at the end of the day, the line opens and the public can verify that it works, even for a legendarily delayed project like Second Avenue Subway, the Berlin-Brandenburg Airport, or the soon-to-open Tel Aviv Subway. It’s a crude mechanism, since the public can’t verify safety or efficiency, but it’s impossible to fake: if nothing opens, it embarrasses all involved publicly, as is the case for California High-Speed Rail. No such mechanism exists for maintenance, and therefore, incompetent agencies have free reins to spend money with nothing to show for it. I recently gave an example of unusually high track renewal costs in Connecticut.
The connection with leakage is that capital plans include renewal and long-term repairs and not just expansion. Thus, SOGR is leakage, and when its costs go out of control, they displace funding that could be used for expansion. The NEC Commission proposal for high-speed rail on the Northeast Corridor calls for a budget of $117 billion in 2020 dollars, but there is extensive leakage to SOGR in the New York area, especially the aforementioned Connecticut plan, and thus for such a high budget the target average speed is about 140 km/h, in line with the upgraded legacy trains that high-speed lines in Europe replace.
Regionally, too, the monetary bonfire that is SOGR sucks the oxygen out of the room. The vast majority of the funds for MTA capital plans in New York is either normal replacement or SOGR, a neverending program whose backlog never shrinks despite billions of dollars in annual funding. The MTA wants to spend $50 billion in the next 5 years on capital improvements; visible expansion, such as Second Avenue Subway phase 2, moving block signaling on more lines, and wheelchair accessibility upgrades at a few stations, consists of only a few billion dollars of this package.
This is not purely an American issue. Germany’s federal plan for transport investment calls for 269.6 billion euros in project capital funding from 2016 to 2030, including a small proportion for projects planned now to be completed after 2031; as detailed on page 14, about half of the funds for both road and rail are to go to maintenance and renewal and only 40% to expansion. But 40% for expansion is still substantially less leakage than seen in American plans like that for New York.
Betterments and other irrelevant projects
Betterments straddle the boundary between high costs and leakage. They can be bundled with the cost of a project, as is the case for the Somerville Community Path for original GLX (but not the current version, from which it was dropped). Or they can be costed separately. The ideal project breakdown will have an explicit itemization letting us tell how much money leaked to betterments; for example, for the first Nice tramway line, the answer is about 30%, going to streetscaping and other such improvements.
Betterments fall into several categories. Some are pure NIMBYism – a selfish community demands something as a precondition of not publicly opposing the project, and the state caves instead of fighting back. In Israel, Haifa demanded that the state pay for trenching portions of the railroad through the southern part of the city as part of the national rail electrification project, making specious claims about the at-grade railway separating the city from the beach and even saying that high-voltage electrification causes cancer. In Toronto, the electrification project for the RER ran into a similar problem: while rail electrification reduces noise emissions, some suburbs still demanded noise walls, and the province caved to the tune of $1 billion.
Such extortion is surplus extraction – Israel and Toronto are both late to electrification, and thus those projects have very high benefit ratios over base costs, encouraging squeaky wheel behavior, raising costs to match benefits. Keeping the surplus with the state is crucial for enabling further expansion, and requires a combination of the political courage to say no and mechanisms to defer commitment until design is more advanced, in order to disempower local communities and empower planners.
Other betterments have a logical reason to be there, such as the streetscape and drainage improvements for the Nice tramway, or to some extent the Somerville Community Path. The problem with them is that chaining them to a megaproject funded by other people’s money means that they have no sense of cost control. A municipality that has to build a bike path out of its own money will never spend $100 million on 3 km; and yet that was the projected cost in Somerville, where the budget was treated as acceptable because it was second-order by broader GLX standards.
Bad expansion projects
Sometimes, infrastructure packages include bad with good projects. The bad projects are then leakage. This is usually the politically hardest nut to crack, because usually this happens in an environment of explicit political negotiation between actors each wanting something for their own narrow interest.
For example, this can be a regional negotiation between urban and non-urban interests. The urban interests want a high-value urban rail line; the rest want a low-value investment, which could be some low-ridership regional rail or a road project. Germany’s underinvestment in high-speed rail essentially comes from this kind of leakage: people who have a non-urban identity or who feel that people with such identity are inherently more morally deserving of subsidy than Berlin or Munich oppose an intercity high-speed rail network, feeling that trains averaging 120-150 km/h are good enough on specious polycentricity grounds. Such negotiation can even turn violent – the Gilets Jaunes riots were mostly white supremacist, but they were white supremacists with a strong anti-urban identity who felt like the diesel taxes were too urban-focused.
In some cases, like that of a riot, there is an easy solution, but when it goes to referendum, it is harder. Southern California in particular has an extreme problem of leakage in referendums, with no short- or medium-term solution but to fund some bad with the good. California’s New Right passed Prop 13, which among other things requires a 2/3 supermajority for tax hikes. To get around it, the state has to promise somthing explicit to every interest group. This is especially acute in Southern California, where “we’re liberal Democrats, we’re doing this” messaging can get 50-60% but not 67% as in the more left-wing San Francisco area and therefore regional ballot measures for increasing sales taxes for transit have to make explicit promises.
The explicit promises for weak projects, which can be low-ridership suburban light rail extensions, bond money for bus operations, road expansion, or road maintenance, damage the system twice. First, they’re weak on a pure benefit-cost ratio. And second, they commit the county too early to specific projects. Early commitment leads to cost overruns, as the ability of nefarious actors (not just communities but also contractors, political power brokers, planners, etc.) to demand extra scope is high, and the prior political commitment makes it too embarrassing to walk away from an overly bloated project. For an example of early commitment (though not of leakage), witness California High-Speed Rail: even now the state pretends it is not canceling the project, and is trying to pitch it as Bakersfield-Merced high-speed rail instead, to avoid the embarrassment.
The issue of roads
I focus on what I am interested in, which is public transport, but the leakage problem is also extensive for roads. In the United States, road money is disbursed to the tune of several tens of billions of dollars per year in the regular process, even without any stimulus funding. It’s such an important part of the mythos of public works that it has to be spread evenly across the states, so that politicians from a bygone era of non-ideological pork money can say they’ve brought in spending to their local districts. I believe there’s even a rule requiring at least 92% of the fuel tax money generated in each state to be spent within the state.
The result is that road money is wasted on low-growth regions. From my perspective, all road money is bad. But let’s put ourselves for a moment in the mindset of a Texan or Bavarian booster: roads are good, climate change is exaggerated, deficits are immoral (German version) or taxes are (Texan version), the measure of a nation’s wealth is how big its SUVs are. In this mindset, road money should be spent prudently in high-growth regions, like the metropolitan areas of the American Sunbelt or the biggest German cities. It definitely should not be spent in declining regions like the Rust Belt, where due to continued road investment and population decline, there is no longer traffic congestion.
And yet, road money is spent in those no-congestion regions. Politicians get to brag about saving a few seconds’ worth of congestion with three-figure million dollar interchanges and bypasses in small Rust Belt towns, complete with political rhetoric about the moral superiority of regions whose best days lay a hundred years ago to regions whose best days lie ahead.
Leakage and consensus
It is easy to get trapped in a consensus in which every region and every interest group gets something. This makes leakage easier: an infrastructure package will then have something for everyone, regardless of any benefit-cost analysis. Once the budget rather than the outcome becomes the main selling point, black holes like SOGR are easy to include.
It’s critical to resist this trend and fight to oppose leakage. Expansion should go to expansion, where investment is needed, and not where it isn’t. Failure to do so leads to hundreds of billions in investment money most of which is wasted independently for the construction cost problem.
There is a common line among German rail advocates that high-speed rail is not a good fit for Germany’s urban geography because the country is more polycentric than Japan or France. Per such advocates, it’s more important to connect small cities to a national network of trains averaging 120 km/h. It’s based on a wrong understanding of what polycentrism really means in the context of an entire country, and I’d like to explain why. A correct understanding would lead to a national effort to complete a high-speed rail program connecting all of the major cities at higher average speeds than 200 km/h, potentially going up to the 230-250 km/h range typical of France.
How Germany and France differ
When Germans speak of the superiority of the German InterCity concept to high-speed rail, the main comparison is France, which Germans are primed to think of as a nation of lazy spendthrifts. So it’s most valuable to compare the urban geographies of these two countries, and only secondarily rely on either other European countries or on Asian examples.
The most glaring difference is that there is no Paris in Germany. Ile-de-France has about 20% of France’s population, and is far and away the richest region, concentrating all the important corporate headquarters, basing its economy not on a specific industry but on its status as France’s primate city. Germany has nothing like this. The largest single-core metropolitan region here is Berlin, which at 5 million people is around 6% of national population. Moreover, cities are somewhat economically specialized, so the wealth of the richest cities is split across Munich’s heavy industry, Frankfurt’s finance, and so on.
Supposedly, this makes high-speed rail a poorer fit for Germany – there’s no Paris to just connect to every other city. But in reality, a high-speed rail network would still connect all the major cities: Berlin, Hamburg, Hanover, Bremen, the Rhine-Ruhr complex, Dresden, Leipzig, Frankfurt, Nuremberg, Mannheim, Munich, Stuttgart, Karlsruhe. Some of the smaller cities, like Erfurt and Fulda, happen to lie on lines between larger cities and are already connected, just not at as high a speed since German high-speed lines almost always have long legacy segments with a top speed of 160 km/h or even less.
And once all the cities are included, Germany turns into better geography for high-speed rail than France. Precise numbers depend on definitions, but around half of the German population lives in the above-listed 13 metropolitan areas of at least 1 million. In France, it’s only one third, and the median French person lives in a metro area of about 350,000; TGVs are thus forced to spend much of their running time on classical lines at low speed to reach cities like Grenoble and Saint-Etienne, and even some larger cities including Nantes, Toulon, Nice, and Toulouse are not on LGVs.
High-speed rail and connectivity
In the above map, the trip times are very aggressive – Berlin-Hanover in an hour is doable nonstop but barely and the sort of advocates who think train performance levels are still stuck in the 1990s may think it is impossible to do better than 1:30. But the 2020s are not the 1990s, thankfully.
The important thing to note is that not only does it connect all major city pairs, but also there is no alternative that has that feature. The Deutschlandtakt without further investments in speed connects Berlin and Munich in 4 hours, which is borderline for high-speed rail; in Cascetta-Coppola, the elasticity of ridership with respect to travel time in Italy ranges between -2.2 and -1.6, so going from 4 hours to 2.5 more than doubles ridership, for less cost than it’s taken to get to 4 hours so far since Germany has built the hardest segment first and much of what remains is in the pancake-flat North German Plain. With high-speed rail, the longest distance between two major cities, Hamburg-Munich, is 3:45, compared with 5:20 in the D-takt.
This also cascades to the roughly half of Germany that lives outside the metropolitan areas. A smaller city like Rostock, Münster, Regensburg, or Halle gets a connection to the national network either way; the D-takt actually only gives Rostock and Regensburg two-hourly rather than hourly connections to the nearest major node. It takes an hour under the D-takt to get between Regensburg and Nuremberg; the connections between Regensburg and the rest of the country depend primarily on how fast trains are between Nuremberg and the other million-plus urban areas.
Germany benefits from having centrally-located train stations everywhere, making transfers already easier than in France, where Paris has four distinct TGV terminals. Getting between two Parisian stations’ lines requires using a bypass, on which trains run at low frequency, at best stopping at Marne-la-Vallée and CDG, both 30 km from city center. In contrast, Germany train stations are set up for through service except Frankfurt, which is about to get an announcement for a through-service tunnel. To the extent that any bypasses are needed here, they’re because a station’s tracks point the wrong way for some through-service, as in Cologne and (even after through-service opens) Frankfurt; in both cases there’s a convenient near-center station, that is Deutz within walking distance of Cologne Hbf and Frankfurt Airport 10 km from Hbf, and at any rate the lines would have far more demand if speeds between major cities rose to French levels, so the frequency wouldn’t suffer.
Polycentricity and high-speed rail
Polycentricity does not make high-speed rail an inappropriate choice for intercity transportation. It’s neutral, and the urban geography of Germany, in terms of density and city size, is conducive to such a network. The question at this point is not about building a single line like Paris-Lyon, but about completing the half-built system that Germany has, and at that scale, having many major cities is not a problem at all.
So why do German activists keep bringing up polycentricity? I have a few explanations, none legitimate:
- Germans look down on France, and bring up the most glaring differences to justify not learning. I’ve spent more than a decade watching Americans make up the silliest reasons why they can’t learn from Europe, reasons that are often unrecognizable to a European (“American cities weren’t bombed in WW2” – but neither was Paris). The same is visible internally to Europe, where Germany will not learn from France or Southern Europe.
- Polycentricity is a convenient excuse to morally elevate rural and pretend-rural life over the big city, a common romantic trope in an arc from 19th-century nationalism to the modern New Left. High-speed rail breaks this pretense: it centers the largest cities, and tells the rest that their participation in national transport comes from their connections to large cities, which the romantics find deeply immoral. For the same reason, the German New Left finds subways less moral than streetcars.
- Older activists are stuck in the past, when they were younger. In the 1980s, European high-speed rail meant Paris-Lyon, and not the national TGV network. At the scale of Paris-Lyon, Germany’s lack of a Paris indeed weakens high-speed rail. But it’s not the 1980s anymore; at this point the question is about completing fast links like Hamburg-Hanover and Erfurt-Frankfurt, not building the first link. My impression is that younger Greens support high-speed rail more than older ones, who joined the party to express opposition to nuclear power rather than support for immigration.
Looking forward rather than backward, nothing in Germany’s urban geography is an obstacle to a connected high-speed rail network. With central stations and less of the population living in truly isolated rural and small-city communities, Germany can expect to greatly surpass any other Western intercity rail network if it builds high-speed rail, more than reaching DB’s pre-corona 250 million ridership target.
Texas Central is a planned high-speed rail system connecting Dallas with Houston, using turnkey Shinkansen technology and private funding. The trains to be used are lightweight Japanese-made N700s, with extremely good performance, and the operating paradigm is to be based on the Shinkansen, without any interface with legacy rail, even in city centers. However, there may still be some conflict with regulators over this, since American rail regulations, since 2018, have been based on European/UIC standards and not on Japanese ones, which are distinct and incompatible. This is supposed to be okay because there is no track sharing at all, the same model proposed by California High-Speed Rail before US regulations under the supervision of the FRA were realigned with UIC ones. And yet, there may be trouble.
None of this is news – these are documents from 2020. See for example here:
Some commenters asserted that FRA is exempting TCRR from any crashworthiness requirements so that the N700 series trainset technology could be imported. This assertion, however, is not supported by the requirements proposed in the NPRM, as FRA makes clear that its approach is to ensure that the trainset is safe for the environment in which it will operate. To this end, FRA is including additional requirements that are not inherent in the JRC approach to trainset structure design. These requirements include a dynamic collision scenario analysis that is designed to address the residual risks that could potentially exist within the TCRR operating environment.32Of particular note, in this instance, is the inclusion of the steel coil collision scenario outlined in § 299.403(c). Despite the safety record of JRC’s Tokaido Shinkansen system, FRA believes that the North American environment poses unique risks with respect to potential objects that might somehow enter the protected ROW, either by accident or on purpose. In this case, FRA believes that requiring dynamic collision scenario analysis using the 14,000-lbs steel coil scenario derived from existing requirements to protect against risks presented by grade crossings can serve as a conservative surrogate for potential hazards that might be present on the TCRR ROW (e.g., feral hogs, stray livestock, unauthorized disposal of refuse). With the inclusion of this dynamic collision scenario, and adaptations of existing U.S. requirements on emergency systems and fire safety, FRA believes it has reasonably addressed risks unique to the TCRR operating environment in a manner that appropriately considers crashworthiness and occupant protection standards for the operating environment intended, while at the same time keeping intact the service-proven nature of the equipment.PDF-pp. 34-35
Of note, the FRA speaks of grade crossings on a line that has none, and demands trains to withstand the impact of a 6.35 ton steel ball that may be dropped from overpasses that do not exist.
This is likely malicious more than incompetent; advocates I know out of California suspect a specific unnamed staffer placed by Ed Rendell who is trying to sabotage the project. This may also involve some lobbying by European vendors, which constantly snipe at competitors within the American market, and even by individual consultants. California had a little bit of this, when competitors started spreading rumors that SNCF was a pro-Nazi organization, and even got some state legislators to make a testimonial bill designed to embarrass SNCF.
It’s a real danger of assuming that foreign public companies that behave responsibly at home will behave responsibly in your periphery. SNCF is subject to public pressure within France, which limits its ability to extract surplus out of riders; this pressure vanishes even right next to France, with majority-SNCF-owned services to Britain (Eurostar) and Belgium (Thalys), which charge considerably higher fares, let alone in the US. The same is true of the other vendors, really, and thus in Britain, franchises owned by EU state-owned railroads like SNCF, DB, and NS are unpopular. Outsourcing the state even to vendors with a track record of responsibility at home will not lead to responsible results, because such outsourcing is an admission that the American state is not capable of adequately overseeing such a project itself and therefore will not notice extravaganza.
I’ve written five pieces about national and transnational traditions of building urban rail: US, Soviet bloc, UK, France, Germany. I’m about to continue this series with a post about Japan, but yesterday I made a video on Twitch jumping ahead to different national traditions of high-speed rail. The video recording cut two thirds of the way through due to error on my part, so in lieu of an upload, I’m writing it up as a blog post. The traditions to cover are those of Japan, France, Germany, and China; those are the world’s four busiest networks, and the other high-speed rail networks display influences from the first three of those.
The briefest description is that the Shinkansen is treated like a long-range subway, the TGV like an airplane at flight level zero, and the ICE like a regional rail (and not S-Bahn) network. China doesn’t quite fit any of these modes but has aspects of all three, some good, some not.
But this description must be considerably nuanced. For example, one would expect that airplane-like trains would have security theater and a requirement for early arrival. But the TGV has neither; until recently, platforms were completely open, and only recently has SNCF begun gating them, not for security but for ticket checks, with automatic gates and QR codes. Likewise, until recently passengers could get to the train station 2-3 minutes before the train’s departure and get on, and only now is SNCF requiring passengers to show up as long as 5 minutes early.

The Shinkansen as a subway
The Shinkansen network has very little branching. Currently there is none south of Tokyo; a short branch to Nagasaki is in planning but will not open anytime soon. To the north, there is more branching, and the Yamagata and Akita Mini-Shinkansen lines, the only legacy lines with Shinkansen through-service, split trains, with one part of the train continuing onward to Shin-Aomori and Hokkaido and another part splitting off to Yamagata or Akita.
Going south of Tokyo, the off-peak frequency to Shin-Osaka is four express Nozomi trains an hour, at :00, :09, :30, :51 off-peak; two semi-express Hikari, at :03, :33; and one local Kodama, at :57. The 21-minute gaps are ugly, but on a train that takes around 2.5 hours to get to Shin-Osaka, they’re not too onerous. Thus, there is a culture of going to the train station without pre-booking a ticket and just getting on the next Nozomi. The ticketing system reinforces this: there is no dynamic yield management, but instead fixed ticket prices between pairs of station depending on seat class. What yield management there is is static: the Nozomi has a small surcharge, to justify excluding it from the JR Rail Pass and so shunt tourists to the Hikari.
This is not literally the headway-management system seen on some unbranched subway systems, like the Moscow Metro and Paris Métro; Moscow keeps time by distance from the preceding train, and not by a fixed schedule. But this is fine: some subway systems are timetabled, like the U-Bahn in Berlin and the Tokyo subway. Tokyo even manages to mix local and express trains on some two-track subway lines with timed overtakes. To the scheduler, the fixed timetable is of paramount importance. But to the passenger, it isn’t – people don’t time themselves to a specific train.
Another subway-like characteristic includes interior layout, designed around fast egress. Shinkansen cars have two door pairs each and platforms are 1,250 mm high with level boarding, enabling 1 minute dwell times even at very busy stations like Shin-Osaka. Trains make multiple stops in the Tokyo and Osaka regions, and even Nozomi and equivalent fastest-train classes on other lines stop there, to distribute loads. There is no cafe car, and luggage is overhead, to maximize train seating space: a 25 meter car has 18-20 seating rows with 1-meter pitch, which is greater efficiency than is typical in Europe.
Station location decisions, finally, are designed as far as practical to be in city centers. Stations with Shin- before their names are new stations, like Shin-Osaka and Shin-Yokohama, but they tend to be sited close to city centers, at intersections with subway and commuter rail lines.
The main drawback of Japan is that the construction costs are very high. This comes from a political decision to build elevated lines rather than at-grade liens with earthworks, as is common in Europe. This preponderance of els has been exported to South Korea, Taiwan, and China, all of which have high costs relative to the tunneling proportion; the KTX, essentially a Shinkansen adapted to an environment in which the legacy trains are standard-gauge too, is notable for having low tunneling costs, as is common in Korea, but high costs on lines with moderate amounts of tunneling thanks to the high share of construction on bridges.
East Asia has high population density, which lets it get away with high costs since the ridership is high enough to compensate – THSR is at this point returning around 4% on very high costs. But in any other environment, this leads to severe problems. China, with lower incomes and fares than in Japan, Korea, and Taiwan, already has trouble paying interest on lines other than the Beijing-Shanghai system. India, building a turnkey Shinkansen as recommended by Japanese consultants, who were burned by Taiwan’s mix of European and Japanese technology on an operationally-Japanese system, is spending enormous sums of money: the Mumbai-Ahmedabad corridor is around PPP$50.6 billion, for 508 km, $100 million/km on a line that’s only 5% in tunnel and even those tunnels could have been avoided by running on broad gauge and using existing a widened legacy right-of-way in Mumbai.
The TGV as flight-level zero air travel
As detailed in New Departures by Anthony Perl, the history of the TGV differs from that of the Shinkansen in a key aspect: the TGV was built after the postwar decline of rail travel (as was the ICE), whereas the Shinkansen was built before it (as was to some extent CRH). The Shinkansen was built in 1959-64: there was no decline in rail evident yet, with only 12 cars/1,000 people in Tokyo in 1960, and the system was designed to deal with growing ridership. In contrast, the TGV was planned after the 1973 oil crisis, in a then-wealthier and more motorized country than Japan, aiming to woo passengers back to the train from the car and the plane.
Previously, SNCF had been engaging in experiments with high speed and high-voltage electrification, inventing 25 kV 50 Hz electrification in the process, which would be adopted by the Shinkansen and become the global standard for new electrification. It also experimented with running quickly on ballasted track – without modifications, the trains of that era kicked ballast up at high speed, there was so much air resistance. But investment had gone to legacy intercity rail, driving up the average speed of the electrified Mistral to 130 km/h and the Aquitaine to 145 km/h. Nonetheless, competition with air was fierce and air shuttles in that era before security theater attracted many people in competition with four-hour trains from Paris to Lyon and Bordeaux.
The TGV’s real origin is then 1973. The crisis shocked the entire non-oil-exporting world, leading to permanently reduced growth not just in rich countries (by then including Japan) but also non-oil-exporting developing countries, setting up the sequence of slow growth under import substitution and then the transition to neoliberalism. France reacted to the crisis with the slogan “in France, we have ideas,” setting up the nuclearization of French electricity in the 1980s, reduced taxes on diesel to encourage what was then viewed as surplus fuel rather than as a deadly pollutant, and the construction of the electric TGV.
Despite the ongoing growth of the Shinkansen then, there was extensive skepticism of the TGV in the 1970s and early 80s. The state refused to finance it, requiring SNCF to borrow on international markets. The LGV Sud-Est employed cost-cutting techniques including 3.5% grades and high superelevation to avoid tunnels, at-grade construction with cut and fill balancing out to avoid surplus dirt, and land swaps for farms that would be split by the line to avoid needing to build passageways.
Construction costs were only 5.5M€/km in 2021 euros. Unfortunately, costs have risen since and stand at 20M€/km, or even higher on Bordeaux-Toulouse. But the LGV network remains among the least tunneled in the world thanks to the use of high grades; in our database the only less tunneled network, that of Morocco, is a turnkey TGV, built at unusually low cost.
As in Japan, the line was built between the two largest cities: Paris and Lyon. Also as in Japan, Lyon could not be served at the historic center of Perrache, but instead at a near-center location, Part-Dieu, which then became the new central business district, as the LGV Sud-Est was built concurrently with the Lyon Metro and nearby skyscrapers, as is typical for a European city wishing to avoid skyscrapers in historic centers. But everything else was different. There were no real intermediate stops the way that the express Shinkansen have always stopped at Nagoya and Kyoto: the LGV Sud-Est skipped Dijon, which instead was served on a branch, and the two intermediate stops on the line, Le Creusot and Mâcon-Loché, are on the outskirts of minor towns and only see a few trains per day each.
Moreover, relying on France’s use of standard-gauge, there was, from the start, extensive through-service beyond Lyon, toward Marseille, Geneva, Saint-Etienne, and Grenoble. Frequency was for the most part low, measured in trains per day. There was little investment in regional rail outside the capital, unlike in Germany, and therefore there was never any attempt to time the connections from Saint-Etienne and Grenoble to the TGV at Part-Dieu.
At the other end, Paris did not build a central station, unlike German or Japanese cities. The time for such a station was, frustratingly, just a few years before work began on the TGV in earnest: RATP was building the RER starting in the 1960s and early 70s, including a central station at Les Halles, which opened 1977. But this was designed purely for urban and suburban use, and the TGV stayed on the surface. The last opportunity for a Paris central station was gone when SNCF extended the RER D from Gare de Lyon to Les Halles. Thus Paris has four distinct TGV stations – Lyon, Montparnasse, Nord, and Est – with poor connections between them.
This turned the TGV into a point-to-point system. Were there a central station, trains could have gone Lille-Paris-Lyon-Marseille. But there wasn’t, and so for Lille-Lyon service, SNCF built the Interconnexion Est, bypassing Paris and also serving Disneyland and Charles-de-Gaulle Airport. When the LGV Atlantique opened, Tours kept its historic terminal, and thus trains went either Paris-Tours or Paris-Bordeaux bypassing Tours. When the LGV Sud-Est was extended south with the LGVs Rhône-Alpes and Méditerranée, trains did not go via Part-Dieu, even though it had always been configured as a through-station for points south, but rather via a bypass serving Lyon’s airport; trains today go Paris-Lyon, Paris-Marseille, or at lower frequency Lyon-Marseille, but not Paris-Lyon-Marseille.
Of note, Japan’s subway-like characteristic is partly the outcome of its linear geography along the Taiheiyo Belt, making it an ideal comparison also for the Northeast Corridor in the United States. But Lille, Paris, Lyon, and Marseille are collinear, and yet the service plans do not make use of that geography. There is no planning around seat turnover: if a train makes an intermediate stop, it’s one with very low ridership, like Mâcon, with no attempt to have seats occupied by Paris-Lyon passengers and then by Lyon-Marseille ones.
Over time, this led to a creeping airline-ization of the TGV. Airline-style dynamic yield management was introduced, I believe in the 1990s. This was after SNCF had spent the 1980s marketing the TGV as 260 km/h for the same fare as 160 km/h; the overall fares on legacy intercity trains and TGVs are similar per p-km, but TGVs have opaque pricing, and are designed to maximize fares out of Paris-Lyon in particular, where air competition vanished. The executives at SNCF are increasingly drawn from the airline world, and, perhaps out of social memory of the navettes competing with 4-hour trains in the 1970s, they think that trains cannot compete with air travel if they take longer than 3-3.5 hours, even though they do successfully on such city pairs as Paris-Toulon.
Having skipped Germany’s InterCity revolution and its refinements in Switzerland, Austria, and the Netherlands, the TGV network has stagnated in the last decade. Ridership is up since the pre-Great Recession peak but barely, only by around 10%. The frequency is too weak for inter-provincial links, where people mostly drive, and in the 1990s and 2000s the TGV network grew to dominate the Paris-province market; there isn’t much of a remaining market for the current operating paradigm to grow into.
While some regional links are adopting takt timetables, for example some of the Provence TERs, SNCF management has done no such thing. Instead, it has spent the last 15 years pursuing airline strategies, including imitation of low-cost airlines, first iDTGV and then OuiGo. A generalist elites of business analysts believes in market segmentation and price discrimination, which do not work on a mode of travel where a frequent, flexible timetable is so paramount.
Among the countries influenced by France, Spain is notable for realizing that it has a problem with operations. In an interview with Roger Senserrich, ADIF head Isabel Pardo de Vera spoke positively of Spain’s efficient engineering and construction, but centered ADIF and RENFE’s problems, including the poor operations. Like Italy and Belgium, and more recently Morocco, Spain learned the concept of high-speed rail from France; also like Italy and Belgium, it mixed in a few German elements, which in the 1980s meant Germany’s more advanced LZB signaling, but at the time, there was no Switzerland-wide takt yet, and the inferiority of French operations and scheduling was not yet evident. But Spain self-flagellates – this is how it learns – whereas France is just a hair too rich to recognize its weaknesses and far too proud for its elite to Germanize where needed.
The ICE as long-distance regional rail
Germany came into the 1960s with some of the most advanced legacy rail in the world, with technology that would be adopted as a Shinkansen standard. This goes back to the 1920s, when Deutsche Reichsbahn was formed from the merger of the state-level railways in the wake of the post-WW1 German Revolution. The new railway regulation, dating to 1925, promoted new kinds of engineering now completely standard, such as the tangential switch. DRB would also experiment with 200 km/h diesel express trains in the 1930s. Even in the 1960s and early 70s, when the most advanced rail tech was clearly in Japan, Deutsche Bundesbahn kept up with rail tech, much like SNCF, inventing LZB signals.
But unlike Japan and France, Germany never built a complete high-speed rail network. The InterCity network, dating to 1971, was designed around fast legacy trains, at slightly lower speeds than available on the express French legacy trains. The key was that city pairs would be served every two hours, with timed connections at intermediate points boosting many to hourly. This was from the start based on a regular takt and turnover, with more expansive service to smaller cities.
High-speed lines in Germany were delayed, and often built on weird alignments. The most important reason is that in the formative period, from 1971 to 1990, there was no such country as Germany. The country was called West Germany, and, much like Japan, had a fairly linear population distribution from the Ruhr upriver to Cologne, Frankfurt, Mannheim, and finally either Karlsruhe or Stuttgart and Munich; but the largest city proper, Hamburg, lay outside this corridor.
The north-south orientation of West Germany contrasted with the rail network it inherited. Until the post-WW1 German Revolution, the rail networks were run by the states, not by the German Empire, and thus interstate connections were underbuilt. Prussia had an east-west orientation, and therefore north-south lines were relatively underbuilt (see for example the 1896 map), and to top it off most north-south routes crossed the Iron Curtain.
To solve many problems at once, but not to solve any of them well, Germany’s first high-speed line connected Hanover, Göttingen, Kassel, Fulda, and Würzburg. Getting to more substantial cities like Hamburg and Frankfurt requires onward through-service at lower speed. The LGV Sud-Est had a minimum curve radius of 3.2 km, and usually 4 km, and can squeeze 300 km/h out of it now, without any tunnels; the Hanover-Würzburg line has a minimum radius of 5.1 km and a maximum grade of 1.25% and is limited to 280 km/h (service runs at 250 km/h), as it was built as a mixed freight-passenger line.
Subsequent lines have, like Hanover-Würzburg, not been complete connections between major cities. Here the difference with France, Italy, South Korea, and China is evident. All are standard-gauge countries, like Germany, and all employ through-service to various degrees. But France opened a complete Paris-Lyon high-speed line in 1981-3, and only the last 30 km into Paris were on legacy trains (since reduced to 8 km with the Interconnexion Est), and likewise Italian, Chinese, and Korean high-speed lines connect major cities all the way. In contrast, this never happens in Germany at longer distance than Cologne-Frankfurt, a 180 km connection. There are always low- or medium-speed segments in between. The maximum average speed between major cities in Germany is either Cologne-Frankfurt or Berlin-Hamburg, a 230 km/h line with tilting trains, both averaging around 180 km/h; the Tokaido Shinkansen, with legacy 2.5 km curves, squeezes 210 km/h out of the Nozomi, and LGVs routinely average 230-250 km/h between Paris and major secondary cities.
Nor are the lower speeds in Germany saving money. The mixed passenger/freight lines have heavier tunneling than they would need if they had 3.5-4% grades. Hanover-Würzburg cost 36M€/km in 2021 euros thanks to its 37% tunneled alignment. German construction costs are not high relative to the tunneling percentage, unlike Chinese or Taiwanese costs, let alone British ones, but the tunneling percentage is in many cases unnecessarily high. This is thankfully not exported to every Northern European country that learned from the InterCity, but the Netherlands, as NIMBY-ridden as Germany, built an unnecessary tunnel on the HSL Zuid and had very high costs even taking that into account; Italy, with an otherwise-French system, likewise overbuilds, as pointed out by Beria-Albalate-Grimaldi-Bel, with viaducts designed to carry heavy freight trains even where there is no such demand.
So the bad in Germany is that the lines have very shallow grades, forcing heavy tunneling, and the costs are so high that the system is not complete. Is there good? Yes!
The InterCity system’s focus on high frequency enables decent service between major cities. Berlin-Munich trains, compromised by the Erfurt detour and subsequent descoping of much of the line, do the trip in 4.5 hours where they should be taking 3 and even 2.5 hours. But it’s not the same as the 4 hours of the pre-TGV Mistral to Lyon or Aquitaine to Bordeaux, the latter of which averaged the same speed as most Berlin-Munich trains today. The Aquitaine ran as a single daily Bordeaux-Paris-Bordeaux round-trip, and another train, branded the Etendard, ran the same route daily but Paris-Bordeaux-Paris. In contrast, DB today connects Berlin-Munich roughly every hour. It’s far more flexible, and the connections to other intercity trains are better.
And just as the TGV’s inexpensive construction has been perfected in Spain while France has slouched on cost control, so has the interconnected system of Germany been perfected on the margins of its sphere of influence, especially in Switzerland. Swiss connections are never fast: the country is too small for 300 km/h trains to make large differences in door-to-door trip times. The average speed on the workhorse Swiss lines connecting the Zurich-Bern-Basel triangle is around 110-120 km/h. But they run on a half-hourly takt, and other lines run on an hourly takt, and connections at the major cities are timed. European urbanism has a long tail of small cities, unlike American or Asian urbanism, and the Swiss takt connections those small cities to one another through regular timed transfers, with investments to prioritize punctuality.
This leads to a false belief among German rail advocates in a tradeoff between French or Spanish speed and Swiss or Dutch or Austrian connectivity. The latter set of countries have higher rail ridership per capita, and even Germany has recently overtaken France’s intercity rail ridership (though not yet per capita), and thus activists in Germany think investing in high speed is a waste. But what is actually happening is that the countries of Europe that look up to France have built high-speed rail, and the countries that look down on France have not; the Netherlands has HSL Zuid but it’s peripheral to the national network and its system is otherwise rather Swiss. Germany absolutely can and should complete its network. It just needs to understand that in certain aspects, countries it is used to stereotyping as spendthrift have done a more prudent job than it has.
Already, the younger rail advocates I meet, like Felix Thoma, seem interesting in applying the Deutschlandtakt concept to a high-speed rail network, rather than to a medium-speed one as the previous generations called for. But Germany is a NIMBY country. NIMBYs blocked French levels of energy nuclearization in the 1970s and 80s, creating the last generation’s Green Party (current leader, Annalena Baerbock, is 40 and came of age after those fights); NIMBYs sue projects they dislike on frivolous grounds until the politicians lose interest, much as in the US with its government-by-lawsuit, and thus high-speed rail on the Hamburg-Hanover line has been stuck in limbo for a generation.
Besides the political deference to NIMBYs, who as in the US are not as powerful as either they or the state thinks, the main problem then is unwillingness to merge French and German planning insights where they work. I might also add Japanese insights – the Shinkansen is far more efficient with platforms than any European railroad – but they’re less important here or in France than in the UK, which is a ridiculously high-cost version of French planning.
China as a mixture of all modes, some good, some awful
When I started planning this video and now post, I was puzzling over where to slot China. Other systems seemed fairly easy to slot as Japanese, German, or French, with the occasional special feature (insanely high UK costs, HSL Zuid in an otherwise Swiss intercity takt system, Korean standard-gauge adaptations). But China is its own thing. It makes sense: on the eve of corona, China had 2.3 billion annual high-speed rail riders, comfortably more than than the rest of the world put together; Japan, the second busiest network, had 436 million. In Europe, only France has more high-speed rail ridership per capita, by the smallest of margins.
Historically, the system should be viewed as having borrowed liberally from other systems in richer countries that built out their networks earlier. Among the three prior traditions, the one most similar to what CRH has converged on is the Shinkansen, and yet there is significant enough divergence I would not class CRH as a direct Shinkansen influence the way I do the KTX and THSR. This also mirrors the situation for rapid transit: China displays clear Soviet influences but has diverged sufficiently that it must be viewed as a separate tradition now.
The most important feature is that CRH evolved on the cusp of the decline of rail in favor of cars and planes, a decline that has been more complete in Western countries. In the 1980s and early 90s, China was already growing very quickly; this was from a very low base, so it was not noticed in richer countries, but it was enough that there were already motorization and domestic air travel competing with China Railway. This led to a multi-phase speed-up campaign, announced in 1993 and implemented from 1997 to 2007.
At this point, construction was on legacy alignments to legacy stations. In the North China Plain, the railroads were straight thanks to the flat topography, and so what was needed was investment in the quality of the physical plant – the sort of investments figured out in midcentury France and Germany, adapted by the Shinkansen. This was not trivial, not in a then-low-income country like China, but it was not enormously expensive either. At the same time, there was growing electrification in China, using 25 kV 50 Hz, leading to higher and higher train classes, all charging premium fares over the third-world tickets for traditional trains. At the apex was the D class, covering 200 km/h EMUs; the one time I rode a train in China, a day trip from Shanghai to Jiaxing and back in 2009, the way back was on a D class train, which had the comfort level and speed of the Northeast Corridor, topping at 170 km/h and averaging maybe 110. This investment has continued, and as of 2019, 72% of the network is electrified.
But China was already looking for more. In 2008, the Beijing-Tianjin high-speed line opened, as the world’s first 350 km/h line. In the financial crisis’s aftermath, China rapidly built out the network as fiscal stimulus, and by 2011, ridership overtook the Shinkansen’s as the world’s largest. Without legacy considerations, the system is built for 380 km/h, even though trains run at 350 km/h, and express trains average 280-290 km/h.
Like the United States and unlike Japan or most of Western Europe, China has an extensive freight rail network. Its approach is the opposite of Germany’s: high-speed lines are dedicated to passengers, and some are officially called passenger-dedicated lines, or PDLs, to make this clear. Freight trains go on the legacy network. Regional rail in China is very weak; the few lines that exist are new-builds, rather like long-range subways, and frequency is often lacking, the Beijing lines branded as S-Bahn barely running off-peak. With nearly all intercity rail having moved over to CRH, the legacy network is relatively free for freight use, even coal trains, which are slow and care little for reliability improvements for higher-end intermodal cargo.
However, the passenger-only characteristic of CRH’s system does not mean it’s employed French cost-cutting techniques. Rather, lines run almost exclusively on viaducts and have shallow grades, raising construction costs as in the rest of East Asia. Stations are newly-built at high expense: Beijing South cost 7 billion yuan, which in today’s PPP dollars is around $3 billion. There are many tracks and no economization with fast turnarounds as in Japan, and station layouts are comparable to airports, with some security theater.
Beijing South is at least just outside the Second Ring Road. Other stations are farther out. This is not just the beet field stations that characterize TGV service to small cities like Amiens or Metz, but also outlying stations in major centers. Shanghai Station only sees high-speed trains on the local line to Nanjing, providing a dedicated track pair equivalent to Kodama service while Nozomi-equivalent trains continue on to Beijing on their own tracks. The trains to Beijing get a separate Shanghai station, Hongqiao, colocated with the city’s domestic airport. The connecting subways tend to be better than at true beet field stations in France, which miss regional rail connections, but those stations are still well outside city center.
China is moreover exporting the bad more than the good. Chinese-funded projects in Africa are not fast – the average speeds are perhaps midway through China’s speed-up campaign, predating CRH. But they do have oversize, airport-like stations located well outside city centers. This happens even when right-of-way to enter city center exists, as in Nairobi.
On mixing and matching
Understanding these four distinct traditions is important for high-speed rail planning, in those four countries as well as elsewhere, such as in the UK and US. It’s important to understand the tradeoffs that these traditions made, and drawbacks that are not so much tradeoffs as things that didn’t seem important at the time.
Most notably, Britain has oversize stations, spending billions on new terminals such as in Birmingham. This comes from the low efficiency of most European turnaround operations, because most European cities have huge rail terminals from the steam era with a surplus of tracks. When trains need to turn fast, they do: German trains running through Frankfurt, which is a terminal, turn in 3-4 minutes to continue to their onward destination. In Tokyo, where space is at a premium, JR East learned to turn trains in 12 minutes even while giving them a cleaning, and with such tight operations, Britain should be able to fit traffic growth within existing station footprints.
It is also desirable to learn from students who have surpassed their old teachers. Korea has lower construction costs than Japan, Spain has lower construction costs than France and greater understanding of the need to integrate the timetable and infrastructure, Switzerland has perfected the German system to the point that German rail advocacy calls for reimportation of its planning maxims.
In the same way that Taiwan built infrastructure to European specs but is running Japanese trains on it, to its profit and to Japan’s chagrin, it may be advisable to build infrastructure in the French (or, better yet, Spanish) way but then run trains on it the German (or better yet, Swiss) way. But it’s more nuanced than this conclusion, due to important contributions from China and Japan, and due to the focus on having a central station, which France chose not to build in Paris to its detriment.
But in general, I think it behooves countries to learn to implement the following from those four traditions:
- Japan: the best rolling stock, high-efficiency turnaround operations, reliable schedules; avoid excessive viaducts and Japan’s increasing demand for turnkey systems.
- France: passenger-dedicated infrastructure standards (supplemented by Cologne-Frankfurt), land swap deals for at-grade construction, cost control (in the Spanish version – France is deteriorating); avoid TGV rolling stock and airline-style pricing.
- Germany: takt (especially in the Swiss and Dutch versions), open station platforms, integration between timetable and infrastructure, seat turnover, decent rolling stock; avoid empowering NIMBYs and building mixed lines with freight.
- China: separation of passenger and freight operations, very high average speeds; avoid airline-style outlying stations and excessive viaducts.
Separately, because of Noah Smith’s opinions about high-speed rail, today there is going to be an event featuring me and him in which we are going to discuss the issue in an American context, alongside a presentation of the database and what lessons can be drawn from it. You can register here; it’s at 13:00 Eastern US Time, or 19:00 Berlin time.
A few notes regarding our database, because I’m being asked on Twitter, and also because it’s relevant for our research:
This is a well-studied topic
Literature on comparative HSR costs already exists, and some of our internal cost references are to studies on the subject. This is not like subway costs, where the biggest databases I know of prior to ours are a Flyvbjerg paper and a Spanish analysis each with a number of items in the teens. This should not in a way be surprising: the costs and impact of megaprojects are analyzed more than those of smaller projects, and subways are megaprojects of greater size than surface transit or street reconstruction but HSR is of yet greater size. Thus, subways are significant enough that we have been able to find largely complete costs from trade and mass media and government reports, which task is far harder for bus lanes or bike lanes, whereas with HSR, not only is it possible to find complete costs, but also there is extensive public debate and analysis.
I believe our contribution to the discussion, then, is not the database itself, but two new points:
- Contrary to the World Bank report on the subject (see here, starting printed page 39), China does not build HSR especially cheaply. Our findings are not too different from the World Bank’s for lines built up to the publication of the report measured in yuan per km, but we adjust for PPP and therefore the cost in dollars per km is higher, and, moreover, the more recent lines appear to be more expensive. In fact, Chinese costs are higher than European ones. The reason is that China builds its HSR almost entirely on viaduct, whereas in Europe, viaducts are rare, and segments that are not in tunnel are built at-grade or on earthworks.
- There is positive correlation between a country’s HSR costs per km, net of tunnels, and its subway construction costs. This is not perfect correlation, but one can see Britain, the Netherlands, and Taiwan perform poorly in both areas. France and Germany are in the middle. Spain is very cheap. The exceptions are notable: Italy has cheap subways and expensive HSR, which Paolo Beria, author of one of our source papers, attributes to overbuilding and overdesign, with extensive tunnels and freight-friendly grades.
We only include under-construction or open lines
This contrasts with lines that are only in early design and may not yet have a cost – for example, Frankfurt-Mannheim will only publish its cost estimate next year, in a parliamentary budget setting in order to decide whether to proceed (for which the answer is certainly yes, as the benefits to the network are intensive). This also contrasts with canceled and indefinitely postponed lines, such as California High-Speed Rail and the Portuguese lines killed during the Great Recession’s austerity. Canceled lines are upward-biased: the state is likelier to cancel or choose not to build a line if it is more expensive than the average, as we can readily see with California, and therefore we do not wish to compare built with unbuilt lines.
The above analysis is equally true of our subway construction costs database – if a line is canceled, it is purged, even if design or even physical construction began. Gateway for example is under active design and engineering and is therefore included, even if they are still seeking funding, but if it is canceled it will be purged (but if it is rebooted, as I hope, then the sunk cost will be included, as with the Green Line Extension in Boston).
The difference is that our HSR cost database is more historic. It is close to complete for France, Germany, Italy, Spain, Belgium, and Korea, and complete for single-line Taiwan and the Netherlands and for the UK. This is because it’s just easier to find historic data for HSR than for subways, where I wish I could get a complete historic series for big cities with big systems like Paris, Madrid, and Berlin, but can’t even find 1970s-80s costs for any of them. Conversely, ongoing projects make it surprisingly difficult at times to find tunnel and viaduct percentages, and the escape path of going on Google Earth and OpenStreetMaps and measuring is not available.
What is included?
As far as possible, costs are for civil infrastructure, systems, stations, and overheads, but not rolling stock or financing charges. Austria’s Koralmbahn has two sets of numbers, differing by a factor of 2, with one source claiming that it is about whether financing is included. It is my belief that, owing to the high profitability of HSR if cost of capital is ignored, it is best to think in terms of returns on investment and not try to incorporate debt or finance charges into the actual cost.
The importance of avoiding viaducts and tunnels
The Asian tendency to build on viaduct where the line is not in tunnel leads to high costs. Likewise, the use of shallow grades and low superelevation for mixed lines or even for some dedicated lines (the Shinkansen, without any track sharing, hews to 1.5% grads) raises construction costs.
Netting out tunnels is still useful when trying to figure out itemized costs and cost control that is not about what to build, for example about labor or procurement. It is also useful when comparing lines in the mountainous terrain of Austria, Japan, Korea, and Switzerland to the easier North European Plain. But at some point, it is necessary to treat the tunnel percentage as endogenous to the planning system. The viaduct percentage, moreover, is absolutely endogenous.
France in this context does well by keeping lines at grade as much as possible. The only country with less tunneling than France is Morocco, which builds its urban and high-speed trains as if it were France, and, thanks to France’s extensive presence in the Maghreb, French contractors are intimately familiar with the local situation and build cheaply. France and Germany have similar unit costs, but Germany tunnels a lot more, less because of the terrain and more because of either politics (that is, the Erfurt detour for Berlin-Munich, forcing the line to go through thicker mountains) or a misguided attempt at building mixed lines in the 1980s and 90s.
The United States’ high projected budgets for proposed lines that never go anywhere thanks to their extreme costs come from overbuilding more than high unit prices. For example, in Baltimore, a two-track tunnel project designed for exclusive electric passenger train usage turned into a four-track tunnel with enough room for double-stacked freight with mechanical ventilation for diesel locomotives. The scope creep raised the projected budget from $750 million in the late 2000s to $4 billion in the mid-2010s.
