W L Clement Lumber Co 2-4-0 "Porter" Locomotives of the USA


Class Details by Steve Llanso of Sweat House Media

Class 2 (Locobase 11093)

Data from Logging Locomotives 1913 (Philadelphia, Pa: Baldwin Locomotive Works, 1913), p 8. See also DeGolyer, Volume 31, p. 128 and Roy V Wright (Ed.) 1912 Locomotive Cyclopedia of American Practice, Sixth Edition (New York: Simmons-Boardman Publishing Company, 1912), p. 165. Works number was 32436 in December 1907.

This diminuitive wood-burner couldn't have been much shorter and still be a tender engine. When the tiny boiler and wheels were combined with the balloon stack, it gave the impression of a toy. Baldwin explained that it was suitable "...for service where the runs are short and the speed moderate." The tender carried a useful amount of wood fuel (2 cords).

Just before this South Carolina logging road was closed, the GLC sold the engine in August 1910 to the AG & LA Meiklejohn Lumber Company.
