The trains are not mine they are by @AlfredTheGreenB17 Scroll for context So when this movie was being made, they built a real prop locomotive to use for stunts and this particular 4-6-0 could become two different locomotives. The first one was a passenger train to use for the opening of the movie. but the second was the train that the Bad guy of the movie owned, (which is funny considering that the Constitution would be used by the good guys for most of the movie)
