Hi Doug!
I did some research and found a photo taken by “KeyRouteKen” of Southern Pacific steam locomotive 2312, a 4-6-0 type steam locomotive, working the Stirling City Branch at Paradise in the late 1940s. There was no exact date associated with the photo, but this locomotive could have worked the branch in 1945.
We’ll ask around our members and friends and see if anyone else has some information for you.
Thanks.
Pete
