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.
Continuity mistake: Wesley rides his motorbike onto the tracks to catch the money train. We later see him on the money train with Woody, but where has he hidden his bike? He could not have just left it there as it would have been found and he would have been arrested in connection with the crime.Scrappy
Plot hole: When Charlie sets out to hijack the money train, he jumps off the platform onto the tracks as it arrives, in plain sight of the driver and other passengers at the station, and only puts his mask on once he's in position on the tracks. The train conveniently stops right over top of Charlie, allowing him to enter through the conveniently-placed grate on the train's floor.Jay Runkle
Continuity mistake: Halfway into the film, when Wesley Snipes chases 'The Torch' into the subway and they subsequently begin to fight, Wesley causes The Torch to catch fire. If you look carefully at the next shot the train coming towards them is a 5-line train. The train that hits The Torch, however, is an N-line train. (01:03:00)
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.
Plot hole: When the guy known as the Torch first strikes, he is set upon by Grace in the subway before he gets away. Later Grace works undercover in the ticket booth for the cops to catch him. When the torch shows up he recognises her from the earlier scene and knows she is a cop, which is why he creates a diversion to get the other cops away from her. Surely they would have thought of this and not sent Grace in undercover when the guy knew she was a cop.
Visible crew/equipment: Towards the end of the movie, when the money train is getting closer to the passenger train ahead of it, there's a shot from the inside of the passenger train. The camera pans from the people inside it the the back window to show the money getting closer. Look in the glass and you can see the camera man and camera.
