Satsop 4-6-0 "Ten-wheeler" Locomotives of the USA


Class Details by Steve Llanso of Sweat House Media

Class William Shorter (Locobase 11650)

Data from Baldwin Locomotive Works Specification for Engines, 1888, as digitized by the DeGolyer Library of Southern Methodist University Vol 15, p. 232. Works number was 10657 in February 1890.

A diminuitive wood-burning Ten-wheeler, the #3 spent its relatively long career on Washington State's Olympia Peninsula as a logging engine. Not long after it arrived on the Satsop, that railway was absorbed by the Washington Southern. By 1895, the WS was purchased by the Peninsular Railroad, whose name stayed on its tender for the next 40 years.

Finally, in February 1896, the #3 was sold to Simpson Logging of Shelton, Wash, one of the biggest logging companies in the state and one that is still active in 2010. (The 3 expired decades ago ...)
