Blacksher Lumber Company 2-8-0 "Consolidation" Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class David W (Locobase 12584)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 24, p. 132. Works number was 20304 in April 1902.

In 1899, David Blacksher severed his partnership with the increasingly profligate T R Miller and left to join the Blacksher family's lumber operations at Magazine, Ala at the mouth of Chickasabogue Creek near Mobile . In 1902, Baldwin supplied that company with this Consolidation, which was a slightly larger locomotive than those used on the Blacksher-Miller, fitted with the same power dimensions, but fed steam from a bigger boiler with shorter tubes.
