W B Harbeson Lumber Company 2-4-2 "Columbian" Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class 100 (Locobase 14261)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 52, p. 276. Works number was 42689 in December 1915.

Tiny wood-burning double-ended logging engine that accumulated an impressive list of owners over a long career. In order, they were: W B Harbeson, Hixson Lumber, Beach Rogers & Co, Holton & Strickland, Kanfla, locomotive rebuilder/reseller Southern Iron & Equipment. SI&E removed both auxiliary trucks and in October 1922 delivered an 0-4-0ST to Dunlop Sand & Gravel of Petersburg, Va as their #5, but that company returned it very quickly and SI&E sold it in February 1923 to Valco Cypress Company.
