Started a movie called "Human Desire" starring Broderick Crawford, Glenn Ford, and Gloria Grahame (1954). It's a pretty seedy film noir with all the regular bad choices by fairly good people. But, Glenn Ford plays the part of an engineer on the "Central National" railroad. He runs a passenger train on a regular run using FA engines. Lots of train things and heartfelt discussions in the cab. This allows a lot of over-the-rail views from the front. All other cast memebrs work for the railroad, too, so there is a lot of train background even though it is a murder plot and not a train story. Very good film noir movie. imdb plot: Engineer Jeff, returning from Korea, falls in Love with his co-worker Carl's wife Vicky, who both committed a murder... I can't find it on DVD for Region One; only for Region Two.
I looked for a DVD of it awhile back too and was unsuccessful. It is a pretty good movie and the actual story keeps you interested between the train shots. Eric
