Duane is modeling the NP and GN in western Montana to eastern Washington in the late 40's-early 50's allowing steam and diesels. The GN will have the electrified division with two electric yards. All rolling stock is correct for the era and weathered. There is a 65-foot, 20-train hidden staging yard that will enable the dispatcher to bring trains out to the viewing area. From there, an engineer will take over and run the train thru the system and bring it back to disappear again in the staging yard. Three trains will run at the same time during operating sessions, while the dispatcher is making up and receiving trains in the staging yard.
