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.
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.
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.
Visible crew/equipment: When Woody Harrelson comes back home after having been beaten up the second time and he opens the fridge there's a reflection of a man with a white shirt and a black jacket in the microwave.
Continuity mistake: When Wesley Snipes and Jennifer Lopez are drinking in the pub, the beer that Jennifer is drinking changes from full to half empty, a few times while they are talking.
Plot hole: The only reason why Woody and Wesley observe their targets (actually people they are supposed to protect) from another platform can only be that trains can get in between in crucial moments for the sake of suspense enhancement.
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 eleven cars.
Factual error: The #6 train does not go to Wall Street. Its final stop in Manhattan is Brooklyn Bridge-City Hall, 2 stops north of Wall St.
Continuity mistake: Near the end, as Woody Harrelson and Wesley Snipes ride the runaway money train, Jennifer Lopez manages to follow the train in the streets above in her car. Along the way she drives past the same stores at least twice.
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.
Factual error: After John and Charlie jump off the money train, it reverses and derails onto its side, and rolls for some distance in the tunnel, knocking down all support columns in its path. Those columns are not as flimsy as the film suggests, and would actually have sliced the train and/or cause it to buckle, as had happened with a similarly derailed train near the 14th Street-Union Square station in 1991.
