The Alberta Pacific runs from Red Deer, Alberta, to Vancouver BC. There is a branch line that runs down to Osoyoos, BC, where there is an interchange with the Spokane Southern Railroad's Okanagon sub.
These shots are from July 3, 1957, and show locomotive #702 pulling a manifest freight up the 2% grade at Athabaska Crossing, AB.
I tried some of that newfangled color film too, came out OK.
Model notes - Photos shot on my friend Warren's Alberta Pacific Railroad (HO). Locomotive is a Sunset Models D&RGW M-69 class 4-8-2. Rock face was created using techniques developed by Joel Bragdon (check out his "Geodesic Foam" site at https://www.bragdonent.com/).
