There was a PBS Special some years ago about trains. I think it was called Riding the Rails. Johnny Cash was the narrator. He sang several songs about trains. There was one that I've been trying to find. All I can remember now is that he was singing about the elelgance of the old trains and the line in the song was something about "velvet and burgandy". Not much to go on I know. Any train song buffs have any idea?
