HOWDOO,
I hope this isn't too far off-topic, but at least it's railroad oriented.
My all-time favorite RR film is "Emperor of the North" (1973), a Depression-era tale with great acting and lots of train operating shots. Lee Marvin & Ernest Borgnine.
My second favorite is "Unstoppable" (2010), about a runaway train with nobody on board, carrying a dangerous cargo through populated areas. Denzil Washington.
