The MLC was a subsidiary of the Pacific Spruce Corporatino. In 1918, PSC had bought a concession from the Spruce Production Corporation, which was wrapping up the disposal of assets created by the US Forest Service-operated Spruce Production Division.
The MLC, operated the Alsea Southern Railroad, which was built by the SPD as the SPD No 12 and covered 23.4 miles (37.7 km) in the South Yaquina District (about 100 miles/161 km south of the mouth of the Columbia River). According to the specs, this oil-burning logging Mikado would be traveling on 60 lb/yard (30 kg/metre) rail around relatively gentle 15 degree curves. Its ruling grades would be 4% when heading up to the timber stands and 2 1/2% pulling loaded cars. 8" (203 mm) piston valves admitted superheated steam to the cylinders.
Working on the same road and bearing consecutively the heralds of the MLC, C D Johnson (another PSC subsidiary), and Georgia Pacific, the 1 ended its days as a display in the PSC's home town of Toledo, Ore.
