Atomic Train

Atomic Train is a 1999 actionthriller film about an accidental nuclear explosion destroying the city of Denver. It was originally broadcast as a television film on NBC as a twopart miniseries.

The movie is notorious for its factual and plot oversights. Most often quoted is that the train is said to become a runaway when it is still 300 miles west of Denver with a continuous decline ahead. Since this would place it on the other side of the Continental Divide, it should be going generally uphill for most of the first 250 miles, a critical plot flaw.Furthermore, for safety reasons all trains are fitted with Westinghouse air brakes. In the event of a failure, such as an air leak like that which occurs in the movie, the brakes would be fully applied, thus stopping the train, rather than rendering it a runaway. ........
