Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Vol 71, pp. 341+. Works number was 55480 in June 1922.
Pacific States opened its Kangley, Wash sawmill in 1910 and started cutting timber at the rate of 125,000 feet per day. In 1922, when PSL ordered the logging Mikado they numbered 9, the railroad featured 60 lb/yard (30 kg/metre) rail arcing around relatively gentle 11 degree (radii of 521 ft/159 m) curves and climbing ruling grades of 2%. This engine had 8" (203 mm) piston valves. According to Gene Connelly's Baldwin production list, the railroad closed in 1939 and the 9 moved on to operate on PSL's Cascade Timber Company railroad.
