There is a promotional film for "America's last narrow gauge passenger train" that includes scenes on the making of this film. The film is titled "Journey to Yesterday" and does not seem to be listed on the IMDb. Starting in Durango, this film follows the tourist train on it's journey to yesterday. At one point it reaches the location where the "Denver and Rio Grande" movie is being made. It has extensive coverage of the actors at work and especially the "day for night" cinematography being used for some of the movie's night scenes. It also shows the preparation work for the filming of the train collision right up to the collision itself. During the 1990's this film was available on video tape but a recent (2009) check of Amazon.com indicates that this tape is no longer available.
