East Texas & Gulf 2-6-2 "Prairie" Locomotives in the USA


Class Details by Steve Llanso of Sweat House Media

Class 52 (Locobase 11008)

Data from "Logging Locomotives", Record of Recent Construction #96 (Baldwin Locomotive Works, 1918), p. 12-13. See also DeGolyer, Vol 62, pp. 362+. Works number was 52517 in November 1919.

Baldwin's photograph shows a relatively outdated layout in a small branch-line locomotive that was owned by the Lodwick Lumber Company of Hicksbaugh, Tex, which operated the 3.9-mile long ET & G.

After only a few years on the ET & G, the engine departed to work for the Carolina Western.
