Question: Something I've always wondered about trains in the old west on these unfinished railroads, and this movie brought it to my attention again. It shows the track still being built, and it's a single track for one train, no second track along side it. That being said, before the track was finished there is a train going down it one way at the beginning of the movie with passengers. When the train is taken over and forced to steam ahead out of control, it goes off the end of the track and crashes. Well if this hadn't happened, how would the train have gotten back? It is a one way train, on an incomplete track and stopping at a station to drop of passengers and supplies. How would the train have turned around to go the other way again?
