Moscow-Kasaner 4-6-0 Locomotives in Russia


Class Details by Steve Llanso of Sweat House Media

Class K (Locobase 15676)

Data from Russian-language diagram at [link], last accessed 4 January 2014, supplemented by. "Diagrams [of] Locomotives and Tenders", published in Moskva (Moscow), 1935 p. 132-133, PDF supplied by Teemu Koivmaki in his 5 October 2019 email. (Many thanks to Teemu for sending what might never have fallen into Locobase's hands. An indispensable addition to Locobase's library.). Production was shared by Kolomna, Putilov, and Moscow-Kasaner shops.

Photographs of the K class show an unusual variation on the well-known Walschaert outside constant-lead valve gear.
