Factual error: When Baldwin is in the old Caddy convertible driving alongside the train, he sets the cruise control so that he can jump into the train. There are three problems with this. I seriously doubt a Caddy that old, it looked like early 70s, would have cruise control, but they were luxury cars, so it is possible. They show a shot of him setting the cruise control, and it is on a modern-style control stalk, very typical to late 80s and early 90s GM cars. Since the ground along a railroad track is not pavement, it would be very bumpy and uneven, and virtually impossible for the cruise control to keep the car going whatever speed he wanted it to go, going over dumps and holes like that.
Factual error: When the Russians find out Kirkpatrick's name and pull up his personnel record on the computer, his police employee ID card lists his date of birth as 6-23-1965 and the date of issue of the card as 1978, making him only 13 years old at the time of issue.
