I went from Bonifay to Miami once about 10 years ago. It was an hour late to start and several by the time we made it to Miami. The seats leaned back but not quite enough to be comfortable. It was freezing in the car - after an hour (some rule?) the attendant finally allowed us a blanket.
Our destination station in Miami was in a "shady" part of town. Since we were late, the public transportation from the station had already made it's last run. No taxis, no buses, no working phones - we dragged our luggage about 4 blocks. Really an unpleasant end to a long, long ride. I would never do it again unless I had a sleeper car and no particular schedule to meet.
On the good side, the food service car was really nice as was the "solarium." We met many nice travelers from Europe and Australia.
Timeliness is a problem on routes between here and Chicago also. I think this is partly due to the freight trains having priority and since they share the rails Amtrak has to wait. This problem would have to be addressed or people would not be as inclined to use the rail system as often. I'm sure it would be addressed.

You're right. Just create one.
Have you traveled by train in the US ten times?
