The China Railways SL7 (Chinese: 勝利7; pinyin: Shènglì; lit. 'victory') class steam locomotive was a class of 4-6-2 express passenger steam locomotives operated by the China Railway. They were originally built for the South Manchuria Railway (Mantetsu) to pull the Asia Express[1] - Mantetsu's signature train and most iconic locomotive, whose images were used on fliers, posters, postage stamps, and even children's school textbooks, as a symbol of technology and modernism in Manchukuo and was used to demonstrate the success of Japan's imperial project.[2]
