Watching a train related movie over the weekend prompted me to search this stale but always relevant post on the forum.......
I watched 1951's "Strangers On A Train" by Alfred Hitchcock with some nice inside scenes of Pullmans and Observation Cars as the protagonist meets his adversary. Neat SP dining car china and Pullman items in view. Other train scenes of New Haven equipment and stations I believe.
Agree with lots of folks in the thread. "Emperor Of The North" ranks high on my list along with "The Train"
Some things I did not see mentioned in the thread....
You might like "Danger Lights" a 1930 classic for train scenes filmed entirely on the Milwaukee Road. Plot a bit corny for some but, I love the movie, especially the company railroad picnic with a "real" locomotive tug of war!! Great movie for steam fans and Milwaukee Road lovers paradise.
https://youtu.be/7gb_xMbCqx4"Runaway" is a 1973 TV Movie Of The Week about a ski train that has its brakes "ICE UP" and away they go down the mountain! Filmed on DR&GW ski trains of long ago. No plot spoiler here but you'll like (or laugh) at the climactic ending. Stars Ben Johnson as a ready to retire engineer.
