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 http://www.lakebistineau.com/history/Yellowpine.htm 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.
