Many times, frequent Amtrak rider mainly in the 1990s. Second night the sleep comes much easier. Always fun though. Roughest ride was on the recently acquired by UP (at the time) Missouri Pacific south of St Louis. Weeks after that ride Amtrak rerouted the Texas Eagle for the rest of the summer for track work on that segment. Unforgettable night though, not much sleep but some cool last scenes of MP power.
Always nice in the morning to get the complimentary coffee, juice, and a newspaper.
