Krotovka-Sergeivsk / Samara Zlatoust 2-6-2 Locomotives in Russia


Class Details by Steve Llanso of Sweat House Media

Class unknown (Locobase 12215)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 20, p. 190. See also "Locomotives Recently Constructed by the Baldwin Locomotive Works", American Engineering & Railroading Journal, Volume 70, No 12 (December 1896), p. 340. For the railways see Russia. Ministerstvo putei soobshcheniya (John Marshall (translator), Guide to the Great Siberian Railway (St Petersburg: Artistic Printing Society, 1900), esp. pp. 89 (K-S) and 81- (S-Z). Works numbers were 15008-15012 in August 1896.

The K-S was an 80-verst (63.6-km, 39.4 mile) line that ran from Krotovka to the mineral springs at Segievsk. This quintet of tanks was almost immediately transferred to the Samara Zlatoust, which linked to the K-S at Krotovka.

The Samara Zlatoust was much longer, covering 1,057 versts (1,120 km, 696 miles) from Baratka on the Volga to Cheliabinsk. It was described in 1900 as the "principal link" between Russia's European network and the main Siberian line.
