Other mistake: When Michael borrows a cell phone on the train, he goes to the back to get a signal. In reality, walking around on a moving train does not do anything because you're already moving.

Factual error: To derail the train, the bad guys shoot the operator, which causes the train to speed out of control. This is a well-known fallacy. All trains use a "dead-man switch" that will stop the train if the operator dies or loses consciousness.
Michael MacCauley: What happens when you find 'em?
Joanna: They die. Hypothetically.
Question: Why does the weather and road/ground change so much (dry, rain storm, wet, snow) in the beginning of the movie from the kitchen to the train station?
Answer: The opening credit scene (waking up, in the kitchen, the drive, being on the train, and walking through the terminal) is montage where each cut represents another day in Michael's life. It's meant to show the monotony of his life through the whole year (or even years) and how he follows the same routine everyday.
