Kentucky-Lumber Company 2-6-2 "Prairie" Locomotives in the USA


Class Details by Steve Llanso of Sweat House Media

Class 6 (Locobase 14948)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 65, pp. 169. See also company ad in Lumber Trade Journal, Vol 66 (15 July 1914), p. 86. Works number was 53363 in June 1920.

Kentucky-Lumber (the hyphen is theirs) had its headquarters in Lexington. They advertised themselves as manufacturers of Delta Red and Sap Gum Tupelo, Kentucky White Oak, Poplar, Ash, Chestnut, and Southern Hardwoods. It operated band mills at Burnside and Williamsburg, Ky, La Follette, Tenn, Sulligant, Ala, and Ruleville, Miss.

This light logging Prairie was a standard Baldwin type that had been sold to many logging companies over the years. According to Gene Connelly's production compilation, the 6 was delivered to the band mill at Sulligant. Not too long after it arrived, however, K-L sold the engine to locomotive rebuilder/recycler Birmingham Rail & Locomotive, who found a buyer on 31 October 1923 in Foshee Lumber of Willow, Fla. Foshee would later sell the locomotive to Cummer Sons Cypress of Lacoochee, Fla near the Pasco-Hernando border.
