Lufkin Land & Lumber 2-6-0 "Mogul" Locomotives in the USA


Class Details by Steve Llanso of Sweat House Media

Class 11 (Locobase 11547)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 26, p. 43. Works numbers were 23717 in February 1904. See also the Tap Line archive at []

Lufkin Land & Lumber was located in eastern Texas. Although LL & L briefly operated the Texas & Louisiana Railroad, that line was was absorbed by the St Louis-Southwestern (Cotton Belt) in June 1903. Lufkin continued to buy locomotives for its own use and the Mogul was delivered early in 1904.

Lufkin later sold #11 to the Louisiana & Pacific Railway which, as the Tap Line Case backgrounder said, was a "peculiar property." Its chief uniting feature was its service to western Louisiana logging companies, but it was made up of 5 segments , each of whch was geographically independent of the other four. The 11 was renumbered 150.


Class 15 (Locobase 14146)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 48, p. 255. Works number was 33353 in April 1909.

This Texas timber harvester had bought two other Moguls (Locobase 11547 and 12793) before adding this one, which was slightly smaller than the 1904 engine. It eventually operated under the Long-Bell Lumber herald.


Class 3 (Locobase 12793)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 27 p. 264. Works numbers were 26056 in July 1905 and 26204 in August.

According to the specifications, this pair of Moguls was lettered according to the particular railway that operated within Lufkin's east Texas empire. 3 trailed a tender identifying the DeSoto Land and Lumber Company while 7's tender bore the Prestridge & Buchanan name.

3 was later sold to the Vicksburg, Shreveport & Pacific as their 307, then very shortly went to Cady Lumber, Baldwin converted the engine to burn oil on the Apache Railway out of McNary, Ariz. 7 later went to the Angelina & Neches River (also part of the Lufkin system) and bore the new number 101. It ended its days working for Foster Lumber near Fostoria, Texas as their #5.
