Data from Baldwin Negative 7802 as digitized by the DeGolyer Library of Southern Methodist University and archived at [],321. See also DeGolyer, Vol 65, pp. 21+. Works number was 54231 in January 1921.
Although similar in many respects to the 1914 engine shown in Locobase 14050, this logging Prairie was considerably heavier, had a larger boiler pressed to a higher degree, slightly larger grate, was fitted with a good-sized superheater, and served its larger cylinders through 8" piston valves.
Long-Bell soon redeployed this locomotive on the Sibley Lake Bisteneau & Southern Railway. See Locobase 13449 for a history of the SLB & S.
Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 45, p. 46. See Helene King, "The Economic History of the Long-Bell Lumber Company", MS Thesis Submitted To The Faculty of the Louisiana State University and Agricultural And Mechanical College, August 1936 at [] . Works number was 41173 in March 1914.
The ASLLC was organized at Pine Bluff, Ark on 14 June 1911 to harvest hardwood, which was a first for its parent Long Bell Lumber Company.
