Character mistake: Engine #1206 is instructed to take the nearest siding upon hearing the news of the oncoming train. Frank does the maths and determines that they will not fit into that siding. He states the siding being 4011 feet between signals, with about 2500 of actual usable space. Engine #1206 with 25 cars would only equal 1580 feet, giving them more than enough room to clear in the first available siding.The average length of a railroad car is 60 feet. Even if the cars were considered "long", total 25 cars would have fit into that siding.
Character mistake: In the reporting of the scene where the Pennsylvania police shoot at the train trying to hit the red button that would stop the train, the report said they were firing shotguns. They were firing M16 rifles.
