Recommended Read: Randal O’Toole Gets High-Speed Rail Wrong

Wednesday, May 12, 2021

Now that there’s decent chance of US investment in rail, Randal O’Toole is resurrecting his takes from the early Obama era, warning that high-speed rail is a multi-trillion dollar money sink. It’s not a good analysis, and in particular it gets the reality of European and Asian high-speed rail systems wrong. It displays lack of familiarity with rail practice and rail politics, to the point that most nontrivial assertions about rail in Europe and Asia are incorrect.

More broadly, the way O’Toole gets rail investment here wrong comes from making unexamined American assumptions and substituting them for a European or Japanese reality regarding rail as well as rail politics. If the US can’t do it, he thinks other countries can’t. Unfortunately, he’s even unfamiliar with recent work done on American costs, when he compares the Interstate system positively with recent high-speed rail lines.

High-Speed Rail Profitability: France

I’m currently working on building a database similar to our urban rail costs for high-speed rail. Between this and previous iterations of analyzing the TGV, I’ve been reading a lot of internal French reports about its system. Thankfully, France makes available very good public information about the costs and technical specifications of its system. It helps that I read French, but the gap between what’s available for France and Belgium (see for example line schemas) is vast. This provides crucial background that O’Toole is missing.

The most important thing to understand is that the TGV network is profitable. The Spinetta report on the fiscal losses of SNCF makes it clear, starting on p. 60, that the TGV network is profitable, and recommends favoring its development over the money-losing legacy networks, especially the branch lines. The report even calls for closing weak branch lines with only a few trains a day, which I called the Spinetta Axe at the time, in analogy with the Beeching Axe. Due to public outcry the state rejected the cuts and only implemented the organizational changes promoted by the report.

Moreover, all lines are very profitable excluding the cost of fixed capital. The Spinetta report’s TGV section says that operating costs average €0.06/seat-km, which is around 0.085€/p-km, despite overstaffing of conductors (8 per conventional 400-car TGV) and extensive travel on legacy track at low speed and higher per-km labor costs. Average TGV fare revenue per an ARAFER report from 2016 is 0.10€/p-km – compare p-km on p. 15 and revenue on p. 26. This is typical for Europe – RENFE and DB charge similar fares, and the nominal fares seem to have been flat over the last decade.

What’s dicier is cost of capital. In all other European countries for which I’m aware of the process, all of which are Northern rather than Southern, this is done with benefit-cost analysis with a fixed behind-the-scenes discount rate. France, in my view wisely, rates lines by their financial and social rates of return instead. A 2014 report about the Bordeaux-Toulouse LGV, recently given the go-ahead for 7.5 billion €, warns that the profitability of LGVs decreases as the system is built out: the LGV Sud-Est returned 15% to SNCF’s finances and 30% to French society (including rider consumer surplus), but subsequent lines only returned 4-7% to SNCF’s finances, and Bordeaux-Toulouse is likely to return less, 6% including social benefits per the study and at this point slightly less since the study assumed it would cost slightly less than the current budget.

The general theme in the French discourse on trains is that the TGV network is an obvious success. There absolutely is criticism, which focuses on the following issues:

However, saying that the existing network is a failure is the domain of cranks and populists. It is unrecognizable from the discussion of transportation investments in France.

What O’Toole says about high-speed rail

O’Toole’s understanding of internal French (or Spanish, or Japanese) issues is weak. This isn’t surprising – Americans to a good approximation never have good insights on the internal issues of any other country, even when it speaks English. The American political sphere, which includes political thinktanks like Cato, is remarkably ignorant globally, and rather incurious. As a result, what he says about the TGV is based on an Americanized understanding. To wit:

Bus-rail competition

The Northeastern United States has a weak rail network: Amtrak averages vintage 1960s speeds and charges 2-4 times the per-km fare of the TGV. As a result, an ecosystem of private intercity buses has developed, starting with unregulated ones like Fung Wah and, as they were shut down, corporate systems like Megabus and Bolt. O’Toole is fond of these buses, with their lower fares and road-like lack of integration between infrastructure and operations.

And thus, he claims, falsely, that European high-speed rail cannibalized profitable buses. This is unrecognizable from within Europe, where intercity buses were underdeveloped until recently. In France, US-style intercity buses are called Macron buses, because the deregulation that brought them into existence passed in the mid-2010s, when Macron was the economy minister. They complement high-speed rail but do not replace it, because trains get me from Paris to the German border in 1:45 and buses don’t.

To be fair, TGV ridership has been stagnant in the last few years. But this stagnation goes back to the financial crisis, and if anything ridership picked up starting 2017 with the opening of the LGV Sud-Europe-Atlantique. So the buses are not even outcompeting the trains – they thrive in the gaps between them, just as historically they did on international routes, where rail fares are considerably higher and ridership lower.

High-speed rail construction costs

O’Toole looks at the most expensive few lines possible:

Britain’s 345‐​mile London–Scotland HS2 high‐​speed rail line was originally projected to cost £32.7 billion (about $123 million per mile) and is currently expected to cost £106 billion ($400 million per mile).

International comparisons of high-speed rail costs exist, and Britain’s costs are by far the worst. For example, a 2013 Australian comparison looking at the prospects for such a system in Australia finds that High-Speed 1/CTRL, the line linking the Channel Tunnel with London, cost A$134 million/km, and the second costliest line in the dataset was thee 94% tunneled Bologna-Florence line, at A$95 million/km.

French costs up until the LGV Bordeaux-Toulouse stood around $25-30 million per km in 2021 dollars, net of tunnels. German costs are similar, but German lines have far heavier tunneling than France, a range of 26-51% in tunnel compared with 0-6% in France. One reason is topography. But another is that Germany prefers mixed-use passenger-freight lines, which forces higher construction costs as freight requires gentler grades and, since superelevation must be lower, wider curves; France, like Japan and China, builds dedicated passenger lines, and, unlike Japan or China, keeps them largely at-grade to reduce costs.

O’Toole says, without more references, that it would cost $3-4 trillion to build a US-wide high-speed rail network. But the official Obama-era crayon, at 20,000 km, would be $500 billion at tunnel-free European costs, or maybe $600 billion with 5% tunneling, mostly in difficult places like California and across the Appalachians.

Freeway costs

O’Toole proposes more freeways, and says that to build the Interstate system today would cost $530 billion so it’s better than high-speed rail. Here is where his lack of knowledge of the most recent literature on infrastructure costs is a serious drag on his analysis: Brooks-Liscow establish that there was a large real increase in Interstate cost throughout the life of the program, so a budget that’s really a mixture of cheaper early-1960s construction and more expensive construction in the 1970s is not applicable today.

The same issue affects rail costs: the LGV Sud-Est cost, in today’s money, around $8 million/km, which cost would never recur. Brooks-Liscow explain this by greater surplus extraction from citizen voice groups, which demanded detours and route compromises raising costs. This appears true not just diachronically within the US but also synchronically across countries: so far, the low-cost subways we have investigated are all in states with bureaucratic rather than adversarial legalism, while medium-cost Germany is more mixed. Politicized demands leading to more tunneling are well-documented within Germany – the Berlin-Munich line was built through a topographically harder alignment in order to serve Erfurt, at Thuringia’s behest.

So no, today costs from the 1960s are not relevant. Today, urban motorway extensions cost double-digit millions of dollars per lane-km, sometimes more. The I-5 improvement project in Los Angeles is $1.9 billion for I-5 South, a distance of 11 km, adding two lanes (one HOV, one mixed traffic) in each direction. It’s possible to go lower than this – in Madrid this budget would buy a longer 6-lane tunnel – but then in Madrid the construction costs of rail are even lower, for both metros and high-speed lines.

The discourse on profits

In contrast with the basic picture I outlined for the TGV, French media and researchers often point out threats to rail profitability. This can easily be taken to mean that the TGV is unprofitable, and if one has an American mindset, then it’s especially easy to think this. If SNCF officials say that 20% of TGVs lose money, then surely they must be hiding something and the figure is much higher, right? Likewise, if Spinetta says that the TGV network is profitable but not all trains are, then surely the situation is even worse, right?

But no. This is an Americanized interpretation of the debate. In the US, Amtrak is under constant pressure to show book profits, and its very existence is threatened, often by people who cite O’Toole and other libertarians. Thus, as a survival strategy, Amtrak pretends it is more profitable than it really is.

This has no bearing on the behavior of railroads elsewhere, though. SNCF is not so threatened. The biggest threat from the perspective of SNCF management is union demands for higher wages, and therefore, its incentive is to cry poverty. Nobody in France takes out yardsticks of farebox recovery ratios, and therefore, nobody needs to orient their communications around what would satisfy American libertarians.

Energy

Within the European high-speed rail research community, the energy efficiency of high-speed rail is well-understood, and many studies look at real-world examples, for example the metastudy of Hasegawa-Nicholson-Roberts-Schmid. In fact, it’s understood that high-speed rail has lower energy consumption than conventional rail. For example, here is García Álvarez’s paper on the subject. This is counterintuitive, because higher speeds should surely lead to higher energy consumption, as Hasegawa et al demonstrate – but high-speed lines run at a uniform speed of 200 or 250 or 300 or 350 km/h, whereas legacy rail has many cycles of acceleration and deceleration. At speeds of up to about 200 km/h, nearly all electricity consumption is in acceleration and not maintaining constant speed, and even at 300 km/h, a late-model high-speed train consumes only above one third of its maximum power maintaining speed.

Instead of this literature, O’Toole picks out the fact that all else being equal energy consumption rises in speed, which it is not equal. Garcia in fact points out that higher speeds are better for the environment due to better competition with air, in line with environmental consensus that trains are far superior on well-to-wheels emissions to cars and planes. Worse, O’Toole is citing Chester-Horvath’s lifecycle analysis, which is not favorable to California High-Speed Rail’s energy efficiency. The only problem is that this paper’s analysis relies on a unit conversion error between BTUs and kWh, pointed out by Clem Tillier. The paper was eventually corrected, and with the correct figures, high-speed rail looks healthy.

Competition with cars and planes

Where high-speed rail exists, and the distance is within a well-understood range of around 300-800 km, it dominates travel. A 2004 report by Steer Davies Gleave has some profiles of what were then the world’s main networks. For Japan, it includes a graphic from 1998 on PDF-p. 120 of modal splits by distance. In the 500-700 km bucket, a slight majority of trips all over Japan are made by rail; this is because Tokyo-Osaka is within that range, and due to those cities’ size this city pair dominates pairs where rail is weaker, especially inter-island ones. In the 300-500 km bucket more people drive, but the Shinkansen is stronger than this on the Tokyo-Nagoya pair, it’s just that 300-500 includes many more peripheral links with no high-speed rail service. It goes without saying that high-speed rail does not get any ridership where it does not exist.

In France, this was also studied for the LGV PACA. On p. 14, the presentation lists modal splits as of 2009. Paris-Toulon, a city pair where the TGV takes around 4 hours, has an outright majority for the TGV, with 54% of the market, compared with 12% for air and 34% for driving. Paris-Cannes is 34% and Paris-Nice is 30%, both figures on the high side for their 5:00-5:30 train trips. Lyon-Nice, a 3:30 trip with awful frequency thanks to SNCF’s poor interprovincial service, still has a 25% market share for the TGV.

In general, competition with cars is understudied. Competition with planes is much more prominent in the literature, with plenty of reports on air-rail modal splits by train trip length. JR East, Central (PDF-p. 4), and West all report such market shares, omitting road transport. Many European analyses appeared in the 2000s, for example by Steer Davies Gleave again in 2006, but the links have rotted and Eurostat’s link is corrupt.

O’Toole misunderstands this literature. He lumps all air and road links, even on markets where rail is weak, sometimes for geographical factors such as mountains or islands, sometimes for fixable institutional ones like European borders. In fact, at least measured in greenhouse gas emission and not ridership, all air travel growth in Europe since 1990 has been international. International high-speed rail exists in Europe but charges higher fares and the infrastructure for it is often not built, with slowdowns in border zones. This is a good argument for completing the international network in Europe and a terrible one against building any network at all.

Topography

Even at the level of basic topography, O’Toole makes elementary errors. He discusses the Tokaido Shinkansen, pointing out its factor-of-2 cost overrun. But its absolute costs were not high, which he characterizes as,

The Tokyo–Osaka high‐​speed rail line supposedly made money, but it was built across fairly flat territory

So, first of all, the “supposedly” bit is painful given how much JR Central prints money. But “fairly flat territory” is equally bad. Japan’s mountainous topography is not an obscure fact. It’s visible from satellite image. Per Japanese Wikipedia, 13% of the route is in tunnel, more than California High-Speed Rail.

The United States can and should do better

The report is on stronger grounds when criticizing specifics of Amtrak and California High-Speed Rail. American rail construction is just bad. However, this is not because rail is bad; it’s because the United States is bad.

And there’s the rub. Americans in politics can’t tell themselves that another country does something better than the US does. If it’s in other countries and the US can’t do it, it must be, as O’Toole calls rail, obsolete. This is especially endemic to libertarians, who are intellectually detached from their European right-liberal counterparts (Dutch VVD, German FDP, etc.) even more than the American center-left is from social democrats here and the right is from the mainline and extreme right here.

So here, faced with not too hard to find evidence that high-speed rail is profitable in Europe and Asia, and in fact intercity rail is profitable here in general (direct subsidies are forbidden by EU law unless the line is classified as regional), unlike in the United States, O’Toole makes up reasons why trains here are unprofitable or unsuccessful. He says things that are not so much wrong as unrecognizable, regarding topography, buses, construction costs, debt, the state of the TGV debate, or greenhouse gas emissions.

O’Toole is aware of our transit costs comparison. I imagine he’s also aware of high-speed rail cost comparisons, which exist in the literature – if he’s not, it’s because he doesn’t want to be so aware. And yet, no matter how loudly the evidence screams “the United States needs to become more like France, Germany, Japan, Spain, etc.,” American libertarians always find excuses why this is bad or unnecessary. And then, when it comes to expanding freeways, suddenly the cost concerns go out the door and they use unrealistically low cost figures.

But figuring out why the US is bad requires way deeper dives. It requires delving into the field and understanding how procurement is done differently, what is wrong with Amtrak, what is wrong with the California High-Speed Rail Authority, how engineering is done in low- and medium-cost countries, various tradeoffs for planning lead time, and so on. It requires turning into the kind of expert that libertarians have spent the last 60 years theorizing why they need not listen to (“public choice”). And it requires a lot of knowledge of internal affairs of successful examples, none of which is in an English-speaking country. So it’s easier to call this obsolete just because incurious Americans can’t do it.
