Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 14, p.82. See also [], last accessed 10 January 2012.
Works number was 9112 in March 1888.
This Mogul was the only locomotive operated by the PBMC at the time on its 8-mile Puget Sound & Grays Harbor line in western Washington. The railroad was established in 1882 as a way to get logs to the West Coast's largest sawmill from Mason County. Ned Skinner and John W Eddy bought the PBMC in 1903 and held it for 20 years. Eddy would carry on and after World War II turn to sustainable tree-harvesting;.
2 was sold in 1917 to the Stimson Mill Company.
