Moscow-Kursk 4-6-0 Locomotives in Russia


Class Details by Steve Llanso of Sweat House Media

Class Bp1 (Locobase 12187)

Data from Baldwin Locomotive Works Specification for Engines, 1890, as digitized by the DeGolyer Library of Southern Methodist University Vol 20, p 103. Works numbers were 14697-14715 in February 1896; 14724-14736 in March.

These Vauclain compound Ten-wheelers were powered by naptha. Within a few years, they were described as being "well-used" because of the increasing weight of passenger trains.
