Southern Pacific’s Donner Pass

HO Scale – 1940 to 1955
Owner: Jim Sinclair

Layout Location:
Bixby, OK
“I’m modeling the Southern Pacific over Donner Pass from Roseville California to Truckee with West and East staging yards. The predominant motive power are Cab Forwards and F7’s, ABA’s and ABBA’s in the 1940’s to 1955.
Helper service is required going both east and west over the hill. Southern Pacific began replacing the steam in 1956 with the more efficient diesels.
About 90% of the track is down, some terrain is in.
The Roseville yard is basically complete except for the icing facility.
Four industrial areas are about 98% complete. When completed the RR will support fourteen to eighteen operators and a dispatcher.
The dispatcher will control the double mainline traffic utilizing a computer program.
Eventually a detection system will support the dispatcher in controlling the heavy traffic.”
