Corrected entry: When the bomb explodes the whole train is consumed by flames. The device is apparently located in one carriage and any explosion would be localized to an extent and would likely derail that part of the train, but the whole train explodes as if it was pumped full of gas.
Corrected entry: The scene where Captain Stevens is in the chamber and listening to the recording of his father's speech, the word wav is mis-spelled as wave.
Corrected entry: After Captain Stevens points the Colt .38 revolver at passenger George Troxel, he has it in his hand as he sees Derek Frost leaving. Seconds later he jumps off the train to chase Frost, and he rolls several hundred feet before coming to a rest right next to the revolver which is now lying on the ground at the exact spot he stopped tumbling. (00:57:50)
Corrected entry: In the scene where Colter looks at Derek Frost's license in his wallet, his city/state are listed as Northfield, ILL. Three-letter state abbreviations are outdated. Later when Goodwin and Rutledge are showing the various passengers' ID's on a computer screen, Frost's license now lists his city/state as Chicago, IL. Different city, and the current style 2-letter state abbreviation.
Corrected entry: The second time Captain Stevens enters the source code, Christina calls him "Brian" instead of "Sean". "Brian" is the name of her ex-boyfriend - the one who keeps calling her on her cell phone.
