There are quite a few trains in films but not that many where everthing or the bulk of the story take places on train. My go to would have been 'The Darjeeling Limited' but it was already picked for a another category. I've added a bonus film as there is great part of the film that takes place on a train. Don't forget to check out what Wandering Through the Shelves picked, the blog that started Thursday Movie Picks.
1. The Train
2. Strangers on a Train
