The Shelton Subdivision stretches from Elma, Washington to Shelton, Washington and is approximately 26 miles in length. The primary commodities on the Shelton Sub are lumber, garbage, and propane gas cars. The loaded lumber comes from the Simpson Timber Railroad, which is part of the Simpson Investment Company empire. Garbage comes from the Kitsap County, Washington Olympic View Transfer Station in Bremerton, Washington. The garbage is loaded into container cars and is shipped via rail to Waste Management's Columbia Ridge Landfill in Arlington, Oregon. Propane is heavily used by Kitsap County, Washington residents in the fall, winter, and spring months and comes in via rail for destinations in Shelton, Washington, Belfair, Washington, and Bremerton, Washington.
