Fort Smith & Western 4-4-0 "American" Locomotives of the USA

Class Details by Steve Llanso of Sweat House Media

Class 2 (Locobase 14099)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 41, p. 200. Works number was 38054 in July 1912.

The FS&W was chartered in 1899 to build a 217-mile (350-km) line from Fort Smith, Ark to Guthrie, Okla, which was then the territorial capital, but which lay north of what would become the state capital of Oklahoma City. The expected coal traffic from the Ouachita Mountains simply wasn't enough and the FS&W bought the St.Louis, El Reno & Western in 1906 to extend its main line westward another 42 miles. In 1915, the FS&W gained trackage rights over the Missouri-Kansas-Texas into Oklahoma City.

At around this time, the FS&W took delivery of #2. As with the Missouri & North Arkansas's #23 (Locobase 13268), Tremont & Gulf's 1912 Eight-wheeler shown in Locobase 12894, the 2 was originally ordered by the Midland Pennsylvania. Apparently there was a delay in delivery due to the MP's parlous financial state,. Upon the receipt of a letter on 15 July 1914, the engine was relettered and renumbered by Baldwin's Extra Work Department.

Although traffic grew in the late 'teens and into the 1920s, the road was never robust and the Guthrie-El Reno section was abandoned in 1924. The rest of the railway went into receivership in 1931 and was abandoned in 1939.
