I've only seen that in the northeast. Don't think you'll see much of that riding from Houston to Chicago or heading out west!

Edit: While I haven't ridden trains in every corner of the USA, the best I saw were in the northeast, and I did have a nice ride from Seattle to Portland once, but in middle America you almost never hear of someone riding a train (my grandmother rode them in Texas in the 1930s and a buddy of mine took the 24-hour trip from Texas to Illinois one time, but those are the only stories I have personally heard around here).
