Lyon Cypress Lumber Company 2-6-0 "Mogul" Locomotives of the USA


Class Details by Steve Llanso of Sweat House Media

Class 5 (Locobase 13140)

Data from Baldwin Locomotive Works Specification for Engines, 1890, as digitized by the DeGolyer Library of Southern Methodist University Volume 30, p. 236. Works number was 30954 in May 1907.

LCLC bought this logging Mogul to serve the logging roads that exploited the cypress stands in Livingston Parish, Louisiana. By 1915, the Garyville company had harvested the last of the cypress, renamed the line Lyon Lumber and turned to hardwood and pine. According to a 1916 Poor's Manual of Industrials (Volume 7, p. 1936), Lyon Lumber extracted timber from their own land in Livingston, Ascension, St. James, St. John the Baptist, St. Helena and Tangipahoa Parishes, La. Mills located at Garyville, La., have a daily capacity of 300,000 ft. Annual production, about 70,000,000 ft.
