The movie is truly very good, and reminds me other World War II films which were made during that period of time. If you like suspense tossed in with your history, you will enjoy "The Train."
I attempted to find just a clip of the film for you, but instead found the entire available for you on your computer at this link:
Personally, I would rather watch the movie on TV or by DVD, but if you don't mind being on the computer long enough to watch the entire movie, you may; or if you just would like to see a few minutes of it, you may do that as well. In any case, I hope you will enjoy "The Train" as much as I did!
