Data from DeGolyer, Vol 80, pp. 522. See also W E Lamm, Lumbering in Klamath. Works number was 61306 in April 1930.
Oil-burning logging Mikado that served this Modoc Point, Ore (near Klamath Falls) enterprise. W E Lamm incorporated the lumber company in 1914. Long-Bell Lumber made frequent use of the Lamm Lumber railroad to move the logs it harvested from northern Klamath County. Opened in 1915, Lamm Lumber remained open until 1944, closing a year after several other well-known timber harvesters in the same area.
Like most later Baldwin logging 2-8-2s, the 3 was superheated. It used 10" (254 mm) piston valves. Its large tender suggests longer than usual runs for a timber harvester. Maximum grade reached 7% and curves bent at 25 degrees maximum (radii of 229 feet) over a 50-mile (80 km) network of main and logging roads.
In 1944, Lamm Lumber sold the 3 to the California Western Railroad, which gave it number 44. After 8 more years, the engine was scrapped in April 1952.
