Flap (1970)

Other mistake: A little more than halfway through the movie, they are robbing the train cars by uncoupling and switching the switch direction back and forth to direct the unwanted engine and caboose to the left branch. He switches the switch to go right for the wanted cars and forgets to switch it for the caboose. If you look at the tracks of the switch, it is already set for the train to go left. He then remembers to change the switch and the caboose goes left where it would have already gone.
