Runaway Train (1985)
1 revealing mistake
Directed by: Andrey Konchalovskiy
Starring: Jon Voight, Eric Roberts, Rebecca De Mornay, Kyle T. Heffner
Continuity mistake: When you first see the freight train that eventually would get its caboose smashed, the locomotive is a big one with lots of snow on the front. In all the other shots of this train, it`s a smaller locomotive, and it has no snow on the front.
Rankin: Push the button. We're on a dead-end siding. We're gonna crash in five minutes.
Oscar "Manny" Manheim: Then we'll have a nice, five-minute ride together.
Rankin: You think you're a hero, huh? Shit. You're scum.
Oscar "Manny" Manheim: We're both scum, brother.
Trivia: In the original script Manny was supposed to be a convicted killer but writer Edward Bunker changed it to a safe-cracker because he didn't feel the other prisoners would respect a killer.
Question: Why would the loco derail if the siding switch was set to the siding where the freight train went?
Answer: It wouldn't derail, it would break the bolt on points - the part of switch that moves, causing the points.
