​​The US Has The Best Rail System in the World, and Matt Yglesias Actually Pointed Out the Reason

美国拥有世界上最好的铁路系统,Matt Yglesias其实已经点出了背后的原因

Yglesias has a very good article on why passenger rail is not a bigger deal in the US. In it, he says this (emphasis added):


Instead the issue is that the dismal failure of US passenger rail is in large part the flip side of the success of US freight rail. America’s railroads ship a dramatically larger share of total goods than their European peers. And this is no coincidence. Outside of the Northeast Corridor, the railroad infrastructure is generally owned by freight companies — Amtrak is just piggybacking on the spare capacity.


It is a short article, so it does not go into more depth than this, but I have actually gone further than this and argued that the US freight-dominated rail system is actually far greener and more sensible than the European passenger system. As I wrote years ago at Forbes:

The US rail system, unlike nearly every other system in the world, was built (mostly) by private individuals with private capital. It is operated privately, and runs without taxpayer subsidies. And, it is by far the greatest rail system in the world. It has by far the cheapest rates in the world (1/2 of China’s, 1/8 of Germany’s). But here is the real key: it is almost all freight.


As a percentage, far more freight moves in the US by rail (vs. truck) than almost any other country in the world. Europe and Japan are not even close. Specifically, about 40% of US freight moves by rail, vs. just 10% or so in Europe and less than 5% in Japan. As a result, far more of European and Japanese freight jams up the highways in trucks than in the United States. For example, the percentage of freight that hits the roads in Japan is nearly double that of the US.


You see, passenger rail is sexy and pretty and visible. You can build grand stations and entertain visiting dignitaries on your high-speed trains. This is why statist governments have invested so much in passenger rail — not to be more efficient, but to awe their citizens and foreign observers.


But there is little efficiency improvement in moving passengers by rail vs. other modes. Most of the energy consumed goes into hauling not the passengers themselves, but the weight of increasingly plush rail cars. Trains have to be really, really full all the time to make for a net energy savings for high-speed rail vs. cars or even planes, and they seldom are full. I had a lovely trip on the high speed rail last summer between London and Paris and back through the Chunnel — especially nice because my son and I had the rail car entirely to ourselves both ways.


The real rail efficiency comes from moving freight. As compared to passenger rail, more of the total energy budget is used moving the actual freight rather than the cars themselves. Freight is far more efficient to move by rail than by road, but only the US moves a substantial amount of its freight by rail. One reason for this is that freight and high-speed passenger traffic have a variety of problems sharing the same rails, so systems that are optimized for one tend to struggle serving the other.


Freight is boring and un-sexy. Its not a government function in the US. So intellectuals tend to ignore it, even though it is the far more important, from and energy and environmental standpoint, portion of transport to put on the rails. ….


I would argue that the US has the world’s largest commitment to rail where it really matters. But that is what private actors do, make investments that actually make sense rather than just gain one prestige (anyone know the most recent company Warren Buffet has bought?)


The greens should be demanding that the world emulate us, rather than the other way around. But the lure of shiny bullet trains and grand passenger concourses will always cause some intellectuals to swoon.


Which would you rather pounding down the highway, more people on vacation or more big trucks moving freight? Without having made an explicit top-down choice at all, the US has taken the better approach.
