If you are a light sleeper I would not recommend taking an overnight train, especially on Amtrak. I took the Empire Builder from Seattle to Chicago once and found it essentially impossible to sleep for three days, which killed whatever romanticized notions I previously had about train travel. The train is constantly rumbling over the tracks, the horn is being blared at every crossing, and PA announcements happen throughout the night. Even with earplugs I could not fall asleep. Oh and the train arrived 20 hours late. YMMV, but my advice is to do a short trip before trying a long one!
