Factual error: Near the end of the movie, as the money train is approaching the passenger train, the motorman is communicating on the microphone with dispatch. If you notice, as he is talking, his hand is NOT on the throttle. On the trains in the NYC subway system if the throttle is not depressed the train will stop.
Factual error: In many of the subway scenes the trains carry only three cars. There are no subway trains in New York that carry just three cars. The least amount of cars for a subway train is four, and that number only applies to the shuttle trains. The other lines in the subway carry between eight and twelve cars.
