The 1939 movie "Union Pacific" is on Turner Classic Movies.(Direct TV Ch256).
Never saw it but with the title, gotta check it out.
Gee..Wonder if they paid the UP a royalty?

Back then, UP probably paid them for the publicity.

Not what I thought.....
More drama, than trains.....Oh Well...it is a 1930's movie.

I saw it, but didn't get a lot of train info from it. Got more from Breakheart Pass, to tell the truth, and it was a better film. 8-)
