Donald Liebenson at Armchair Commentary has a large (but probably not complete) list of films about or featuring trains:
“Everybody loves the sound of a train in the distance,” Paul Simon sings, “Everybody thinks it’s true.” There’s nothing truer. Nothing pierces the heart like a lonesome train whistle. Nothing holds the promise of mystery, romance, and adventure like a train bound for somewhere. That thundering locomotive in the kick-ass trailer for Unstoppable looks like it’s bound for trouble. While waiting to see if Denzel Washington and Chris Pine can avert disasters in their path, let’s take a scenic journey aboard some of the most memorable movies in which trains played scene-stealing roles. (The Polar Express is not on this list. Those dead-eyed children give me the creeps).
