Trains in Europe are a pleasure compared to most of the U.S. system. I'm not sure if it's because Amtrak shares track with cargo trains or what, but the ride is pretty bumpy, noisy and much beyond a few hours not worth it with nothing to do and noway to sleep. I've done 20+ hour trips twice on Amtrak and I'll never do it again. I can see doing maybe a D.C. to NYC trip, but the economics of such a trip don't really work out for me over a plane even if door to door the train is only slightly slower (in fact I actually like the drive better).
