"The Train" contains multiple real train wrecks. The Allied bombing of a rail yard was accomplished with real dynamite, as the French rail authority needed to enlarge the track gauge. This can be observed by the shockwaves travelling through the ground during the action sequence. Producers realized after filming that the story needed another action scene, and reassembled some of the cast for a Spitfire attack scene that was inserted into the first third of the film. French Armée de l'Air Douglas A-26 Invaders are also seen later in the film.
