Watched it the other day. Thought it was exceptionally dull (and there's a lot of boring climbing films about at the moment). I don't remember a train. I especially disliked the bit where chap a lamely insults chap b (who is trying voyager), in a barely disguised attempt to show how chummy chap a is with chap b. Chap b is obviously some kind of hero, chap a is obviously desperate for any sort of reflected glory from chap b.
