Louisiana & Pacific 2-6-0 "Mogul" Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class 152 (Locobase 13449)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 36, p. 17. See also [] for a history of SLB & S. Works number was 35640 in December 1910.

After the L & P was abandoned in 1926, the 152 was sold to short line Sibley Lake, Bistineau & Southern, another Long Bell Lumber railroad that was laid down in 1899. The SLB&S was a yellow-pine line that ran from Sibley 28 miles to Camp Long.

The SLB&S website notes that the railroad ran a passenger service "leaving Yellow Pine at 6:15 and arriving at Sibley at 7:00. Then it left Sibley at 7:45 and arrived at Camp Long at 10:40, left Camp Long at 11:00 arriving back at Yellow Pine at noon. " The passenger service ended in 1937 and the railroad was abandoned in 1942 and the rails themselves recycled for wartime use.
