Continuity: After the train comes to a complete and lurching stop, the porter is shown being thrown forward into the bad guys as a lot of baggage falls all over the place. In the final fight scene as Ryback is entering the dining car, all the tables have all their place settings perfectly intact.

Factual error: The footage of the "Nevada Petrol Express" actually is of a similar operation that used to run over the Tecahapi Pass in Southern California. And "Espee" terminology never had "Petrol" in its language.

Plot hole: Now why the heck is one of the stealth fighters anywhere near the train? Stealth fighters use advanced targeting and do not need to be anywhere near their target, yet in the movie the one fighter is so close to the train when it gets blown up that it looks like it's on a collision course.
