Continuity mistake: In the scene where the crooked sheriff is about to throw Kiefer Sutherland off the train, the sheriff doesn't have any blood on his trouser leg, but if you check the shot right before then, he does have blood on his trouser leg.
Continuity mistake: At the lead-in to the fight scene, the train had only passenger cars, with a single baggage car in the normal spot right behind the locomotives. While the train is still in motion, the baggage car is seen at the rear, and a flat car and caboose are now part of the train.
