How long does it take for a train to get from London to Paris? A few hours? We have something like that: the Amtrak northeast corridor line between DC and Boston (with stops in Baltimore, Philly, NYC, and others along the way). Going from DC to NYC is probably somewhat comparable, and I think that takes 3.5 hours. However, going from the east coast to the west coast on a train means several days of travel. We do have that too, with Amtrak. It's horribly slow and no one uses it except people who really want the "see the nation on a train" experience. It's also really expensive, because you'll surely want a sleeper cabin for such a long trip.
