I have traveled across this country by car more than 20 times. I've traveled across this country by train ten times. I traveled across this country by air about 30 times. I like each, at appropriate times, for different reasons. But for some people trains are the holy grail....

Secretary of Transportation Pete Buttigieg wants to make the United States the “global leader” in high-speed rail. That’s like wanting to be the world leader in electric typewriters, rotary telephones, or steam locomotives, all technologies that were once revolutionary but are functionally obsolete today. High-speed trains, in particular, were rendered obsolete in 1958, when Boeing introduced the 707 jetliner, which was twice as fast as the fastest trains today.

Aside from speed, what makes high-speed rail obsolete is its high cost. Unlike airlines, which don’t require much infrastructure other than landing fields, high-speed trains require huge amounts of infrastructure that must be built and maintained to extremely precise standards. That’s why airfares averaged just 14 cents per passenger-mile in 2019, whereas fares on Amtrak’s high-speed Acela averaged more than 90 cents per passenger-mile.

Highways require infrastructure but not this level of precision. While a four-lane freeway costs about $10 million to $20 million a mile, California ended up spending $100 million a mile building its abortive high-speed rail line on flat ground, and it predicted building in hilly territory would cost at least $170 million per mile.

Built with other people's money....
