If I model the Great Northern Railway Portland to Spokane mainline in 2-rail O scale in the 1930-40 era the steam locomotives I want to model is the big 4-8-4 Northerns,4-8-2 Mountains, various Mallets,and electric locomotives in Omaha Orange.
I don't believe the GN had a mainline from Portland to Spokane. Instead they owned, jointly with the Northern Pacific, the Spokane, Portland and Seattle, which did have a mainline from Portland to Spokane.
Of course, you can certainly model that line as if it was GN...

No "Omaha Orange" in the 1930-40 decade. The Omaha Orange / Pullman Green "Empire Builder" paint scheme wasn't introduced until the railroad's first FT diesels arrived - 1944 IIRC. No passenger cars were painted in those colors until the first streamlined cars in 1947, which I think is also when the railroad began painting the electric motors into the green and orange scheme. Before that, they were Pullman Green with Dulux Gold lettering.
That should have been the Spokane via Cascade Tunnel(1927) to Seattle and Portland. The motive power will be 4-8-4 Northerns,4-8-2 Mountains,and Mallets like 2-8-8-0 and 2-8-8-2. Will be in 2-rail O scale,of course
