I started building my HO scale Siskiyou Pacific in 1987 in what used to be the garage of my house. The modeled section includes from about the town of Rogue River to the summit of the Siskiyou Mountians. Interchange with the Southern Pacific is accomplished with staging yards representing Eugene and Black Butte.
Control is by tethered walk around throttles built by the railroad's own shops.
Operation is by a card order system. Up to 5 trains can be operated simultaneously. A full operating session can keep six people busy for five hours moving 150 cars with two dozen trains. Click on Thumbnail images below for full sized picture. Definitely NOT the place to learn how to switch.
