old movie help

[Rail4Pete]

Hi, I need your help ! I captured some screenshot from a documentary '' Golden age of steam trains'' related to a movie. Here are the screenshot of the movie. If you know from what movie it it, please tell me. It has been filmed with the Sierra Railway #3 Rogers 4-6-0. In that movie, the tender is lettered ''Kansas Pacific''. For sure I know it DOES NOT come from the movie ''Kansas Pacific''...I have this movie.
