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


Class Details by Steve Llanso of Sweat House Media

Class 1 (Locobase 14284)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 52, p. 301 and Vol 62, p. 286. Works number was 43349 in May 1916 and 53177 in April 1920.

By the time this big lumber company bought the first little wood-burning logging Prairie, it had expanded from its bases in Moultrie and Thomasville, Georgia. In fact, this wood-burner and its younger sister operated in Florida on very light track (the 2's specification says 30 lb/yard//15 kg/metre.). The grades were "indeterminable" and "negative" and the length of haul 6 to 10 miles (9.7 to 16.1 km). Sparks from the fuel were suppressed by a Rushton Improved cabbage stack.

Not much is known about 1's career, but the 2 has been preserved for display in Naples, Fla. In addition to its service for Barfield Lumber, the 2 operated on the Dowling & Camp lines and later for Lee Tidewater Cypress Company.

NB: The TapLines site describing the Cabbage Stacks at Slater (Fla), those of the Dowling & Camp, describes a smaller engine of 10" x 16" cylinders and 33" drivers. The Baldwin specifications clearly depict an identical sister to the 1. See an extended description of the 2 in Lee Tidewater service at [] .
