Robert Samuelson: Stop High-Speed Pork

Some honesty on high-speed rail from Robert Samuelson in today’s Washington Post:

Somehow, it’s become fashionable to think that high-speed trains connecting major cities will help “save the planet.” They won’t. They’re a perfect example of wasteful spending masquerading as a respectable social cause. They would further burden already overburdened governments and drain dollars from worthier programs – schools, defense, research.

Let’s suppose that the Obama administration gets its wish to build high-speed rail systems in 13 urban corridors. The administration has already committed $10.5 billion, and that’s just a token down payment. California wants about $19 billion for an 800-mile track from Anaheim to San Francisco. Constructing all 13 corridors could easily approach $200 billion. Most (or all) of that would have to come from government at some level. What would we get for this huge investment?

Not much. Here’s what we wouldn’t get: any meaningful reduction in traffic congestion, greenhouse gas emissions, air travel, oil consumption or imports. Nada, zip. If you can do fourth-grade math, you can understand why.

High-speed inter-city trains (not commuter lines) travel at up to 250 miles per hour and are most competitive with planes and cars over distances of fewer than 500 miles. In a report on high-speed rail, the nonpartisan Congressional Research Service examined the 12 corridors of 500 miles or fewer with the most daily air traffic in 2007. Los Angeles to San Francisco led the list with 13,838 passengers; altogether, daily air passengers in these 12 corridors totaled 52,934. If all of them switched to trains, the total number of daily airline passengers, about 2 million, would drop only 2.5 percent. Any fuel savings would be less than that; even trains need energy.

Indeed, inter-city trains – at whatever speed – target such a small part of total travel that the changes in oil use, congestion or greenhouse gases must be microscopic. Every day, about 140 million Americans go to work, with about 85 percent driving an average of 25 minutes (three-quarters drive alone; 10 percent carpool). Even assuming 250,000 high-speed rail passengers, there would be no visible effect on routine commuting, let alone personal driving. In the Northeast Corridor, with about 45 million people, Amtrak’s daily ridership is 28,500. If its trains shut down tomorrow, no one except the affected passengers would notice.

We are prisoners of economic geography. Suburbanization after World War II made most rail travel impractical. From 1950 to 2000, the share of the metropolitan population living in central cities fell from 56 percent to 32 percent, report UCLA economists Leah Platt Boustan and Allison Shertzer. Jobs moved, too. Trip origins and destinations are too dispersed to support most rail service.

Only in places with greater population densities, such as Europe and Asia, is high-speed rail potentially attractive. Even there, most of the existing high-speed trains don’t earn “enough revenue to cover both their construction and operating costs,” the Congressional Research Service report said. The major exceptions seem to be the Tokyo-Osaka and Paris-Lyon lines.

Well said. The rest here.
