Steam loco, steam locomotive, YeA 2-10-0

Notes: The Yea (Amerikanskii - American) locomotives were very similar to the class Ye f/k/s/l engines purchased from Baldwin, AIco and the Canadian Locomotive Company during the First World War. Compared to the earlier locomotives, they had an improved Chassis design and modified cab, chimney and steam dome, and they lacked the hitherto Characteristic railings along the running-plates. A more modern Soviet-type headlamp was also fitted. The Yem (modernizirovannyi - modernised) had modified piston design, etc., while the Yemv (yodopodogrevatel' - feed-water heater) had a dual-pump system (nos 3988-4000). All were ordered under USA/TC auspices and delivered by sea under Lend-Lease arrangements, mostly to Vladivostok in 1944-45. At first many were used in newly-liberated western areas of the USSR, but these so-called Soyuznitsy (Allies) were soon concentrated in Siberia and Kazakhstan. The majority were stored from the early 1960's, and 1042 (12 active) were still in stock in January 1987, though by then mass withdrawals had begun.
