E P Burton Lumber Company 2-6-2 "Prairie" Locomotives of the USA

Class Details by Steve Llanso of Sweat House Media

Class 6 (Locobase 14283)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 52, p. 298. Works number was 41802 in November 1914.

E P Burton Lumber Company was formed in 1901 to exploit timber reserves in North Charleston, SC, as one of the first industries in the area. (Very soon thereafter, the US Navy began work on the Charleston Navy Yard.)

The 6 was delivered as a wood-burning logging Prairie produced to a pattern used by many lumber companies in the Southeast. Even then the company foresaw converting the engine to coal burning. It rolled on 40 lb/yard (20 kg/metre) rail over a 20-mile line.

After its time with EP Burton, the 6 would serve three more logging companies: German Land and Lumber, Limestone, and Dowling & Camp.
