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. (01:17:15)
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: At the end of the boxing fight between Wesley Snipes and Jennifer Lopez her cross pendant disappears and reappears between shots. (00:48:30)
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.
Revealing mistake: When John jumps onto the tracks on his bike, look closely and you can see there is wood or some other material between the rails for him to land on. (01:20:20)
Continuity mistake: Just after leaving the bar, Grace gets into a cab and is driven off. Charlie and John start walking down the road and John has his left arm by his side. When the camera changes his arm is now in front of his abdomen. (00:25:10)
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.
Continuity mistake: When Wesley is driving his motorbike down the subway stairs to catch the money train, we see a couple on the stairs who both move to the side (backs against the wall), but in the next shot with the camera facing up the stairs, the couple have disappeared. (01:19:10)
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.
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 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.
Continuity mistake: When the guards fire at John and Charlie and the mugger, 3 tiles on the pillar get shot clean off. When John and Charlie are emerging from behind the pillar, 2 of the tiles have bits back on the pillar. (00:07:15)
Continuity mistake: The way the first mugger holds Charlie's badge changes between the wide shot and the close up. Notice the top of the badge. (00:04:30)
Visible crew/equipment: Just after breaking down the service gate, John is riding around a corner where a civilian is leaning against the wall on screen left. Look at this extra's feet to see a white tape marker on the floor. (01:19:20)
Visible crew/equipment: When the train stops over Charlie, a camera shadow can be seen on the roof of the train. (01:17:20)
