China State Railways 2-6-2 Locomotives in China
Class Details by Steve Llanso of Sweat House Media
Class YJ (Yuejin/Leap Forward) (Locobase 2162)
YJ production only lasted three years, ending in 1961. Source [
] Production ran from 1958-1961. The first 80 came from the Tangshan Railway Vehicle works. Jinan Railway Vehicle Equipment Company supplied 117 and two smaller works--Mudanjiang (3).and Wuchang (2)--delivered 5.
