I took it from Baltimore to Chicago. The train I was supposed to have been on the previous day derailed near Silver Springs (luckily my ride decided the weather was too nasty to take me to the station--good thinking, apparently). So they bussed us up to Harrisburg, PA, and then I got on the train from there. The train broke down twice and had to have a competing railroad send an engine to pull us up some hill or another.
But it was a fun trip, talked with a bunch of people and hung out in the smoking car most of the time.
