Remember the "shirts and shoes required" signs at the entrances to restaurants? The same would certainly apply in an Amtrak dining car if they posted it.
I was going to mention about the shoes. I seem to recall reading a sign about shoes being required to go between cars, which would basically require them in the dining car. I mean, how would one get into the dining car without going between cars.The only dress code on Amtrak is real shoes.
