Otter Creek Boom & Lumber 2-6-2 "Prairie" Locomotives of the USA

Class Details by Steve Llanso of Sweat House Media

Class 4 (Locobase 12610)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 24, p. 238. Works number was 20244 in April 1902.

The OCB & L logged in the forests of Shaves and McGowan Mountains in Tucker and Randolph Counties in West Virginia in 1897-1914. As the supply dwindled, the compnay sold the 4 to the Waynesville Lumber Company in North Carolina in May 1913.

Two years later, the 4 journeyed to its third owner, the Kessawayne Lumber Company. It's not clear if the 4 ran on the KLC-owned Tuckaseegee & Southeastern Railroad. Locomotive rebuilder/reseller Southern Iron & Equipment bought the 4 in 1917 and rebuilt it as a 2-6-2 tender engine. It then sold the engine in March 1919 to Brasher Lumber Company, which was headquartered in Columbus, Ohio, but operated out of Glendon, Alabama.
