Unspecified 4-6-0 Locomotives in Russia


Class Details by Steve Llanso of Sweat House Media

Class B or G (Locobase 13310)

Data from Captain C E Vickers, "The Siberian Railway in War", The Royal Engineers Journal, Vol 2, No 2 (August 1905), p. 136.

Captain Vickers described this locomotive as standard equipment for both passenger and goods traffic. It was probably a class B or class G Ten-wheeler.


Class Ku (Locobase 734)

Data from "Diagrams [of] Locomotives and , published in Moskva (Moscow), 1935 p. 38-39, PDF supplied by Teemu Koivmaki in his 5 October 2019. (Many thanks to Teemu for sending what might never have fallen into Locobase's hands. An indispensable addition to Locobase's library.)

300 K & Ku built 1907-1909, 1911-1913. 250-mm (9.84") piston valves admitted steam to the cylinders.

Last 4-6-0 class used on Moscow suburban and Moscow-Kazan. Ks scrapped by 1939, the larger Kus lasted until 1950s.
