Bogoslovsk Mining Company 0-4-0 Locomotives in Russia


Class Details by Steve Llanso of Sweat House Media

Class unknown (Locobase 11001)

Data from "Tank Frame Locomotives", Record of Recent Construction #93 (Baldwin Locomotive Works, 1918), p.12. See also DeGolyer, Volume 57, pp. 388+. Works number was 42395 in September 1915. For a description of the Marshall valve gear, see "Marshall's Patent Valve Gear", Locomotive and Railways, Volume III [3], No 28 (April 1902), pp. 34-35.

See Locobase 10996 for a short description of this small tank-engine design sold to several industrial, mining, and agricultural companies.

Bogoslovsk Mining supplied its own brown coal for this tank-frame engine, which was identical in all respects except loaded weight (attributable to a 25-gallon/95-litre increase in tank capacity) to the SMCN engine shown in Locobase 11000.
