The Sunset Valley Railroad (SVRR, formerly the Sunset Valley Oregon System, or SVOS) models 10 prototype railroads as they existed in the Pacific Northwest in 1955. Features include replicating the Southern Pacific (SP) from Portland, OR to Dunsmuir, CA, via their original Siskiyou line, SP’s famous Coos Bay Branch, abundant Spokane Portland and Seattle (SP&S) trackage, independent railroad logging and mining operations, as well as the Great Northern (GN), Northern Pacific (NP), and Union Pacific (UP) operations into Portland.
Scale Rails article from March of 2007 where Bruce Chubb discusses the evolution of the Sunset Valley and the expansion of his previous layout as he moved into a new home. This new layout would be significantly larger than the previous one, and feature more prototypical operations.
The prototypes have been compressed to fit into a 2650 sq ft basement using up to 4 decks. For those desiring a more detailed track plan, a multi-page version is available at HERE. Download the "Guide for Guests and Crew Operating on the Sunset Oregon System" for even more information!
