In the last 4 years I’ve taken a sleeper from Montreal to Moncton in Canada, and from Inverness to London in the UK. I love sleeper trains and would take them more often if I could, but on Amtrak it really doesn’t make sense. The only route I really want is Wilmington DE to New Orleans, and it’s dramatically worse than flying in every way: easily 3x the cost if you’re going to do the trip in comfort, always delayed, and slow as molasses. If there were a train that did this 1700-mile trip in, say, 18-20 hours rather than 28+, I’d consider it just for the fun factor. But as it stands...it just makes no sense when the door-to-door trip by plane takes less than 6 hours.
