Sounds about right. I know I had films from 1948, 1949, and 1951, so this is obviously one of the 1948 or 49 scenes. Its documented in the video, as to who shot and what year, and the train numbers you indicated. I just didn't recall all the info, but remembered the scene being there. One of the things that made the Narrow Gauge on the D&RGW so interesting was not only the railroad and scenery but the fact it lasted another 12 years after all the Standard Gauge Steam was gone on the D&RGW. Thats why the SG movies are scarcer by far.
