State TransCaucasus 0-6-2 Locomotives in Russia


Class Details by Steve Llanso of Sweat House Media

Class CHa1005 (Locobase 12126)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Vol 19, p. 147. Works number was 14086-14087 in September 1894.

Gene Connelly lists the 5 as an 0-4-2T, but the Baldwin specifications show that both have the wheelbase shown above. This distance more likely reflects 3 axles than 2.
