IIRC the USA doesn't really do trains. Also, trains have public seating, which means they Can't Have Nice Things thanks to various anonymous assholes - in comparison, most people don't wreck their own car.
How much of that is the perception of anonymous assholes vs the real thing? American passenger trains used to have open sleeper cars, but not anymore, which is kinda sad because I don't want to have to choose between coach (uncomfortable) and roomette (expensive) on the LA/Chicago route.
the US does a lot of trains, but generally for short distances on commuter corridors, and municipal light rail. we don't do high speed passenger rail, which is probably what you're thinking of.
