There are a lot of trains I'd take in America if they were also had car carriages. There's only one East Coaster that does it. Pity, and I get why (no one else seems to want it) but if it were to happen, I'd be pretty happy. Imagine parking your car on the train, hanging out with your friends in a private room, sleeping on the train and then waking up in Denver and just hopping into your car to go up to Aspen. Nice.
