Visible crew/equipment: In the shot where Diesel 10 races past Thomas and Gordon near the beginning, you can see a black pencil on the left of the screen.
Continuity mistake: During the chase scene at the end of the film, P. T. Boomer (a character cut from the film), can be seen on top of Diesel 10 during the shot where he enters a tunnel.
Other mistake: During the chase scene as the engines go through the tunnel, there is a figurine sitting on the back of Diesel 10. This happens to be the film's original antagonist, P.T. Boomer who was cut from the movie. However, the crew forgot to remove the Boomer figurine from Diesel 10.
Revealing mistake: As Diesel 10 leaves after overhearing Thomas and Percy, a red wire can be seen in his cab.
