The China Railways JF17 (解放17, Jiěfàng, "liberation") class steam locomotive was a class of 2-8-2 steam locomotives operated by the China Railway, built by Hudswell Clarke in the United Kingdom and by the South Manchuria Railway's Shahekou Works in 1931.[1]
At least four of these locomotives were originally built for the Jiaoji Railway, which numbered them in the 600 series.[1] After the establishment of the collaborationist Provisional Government of the Republic of China during the Japanese occupation of China, the North China Transportation Company was formed in 1938 to operate railways in the territory of the Provisional Government, nationalising the various privately owned railways, including the Jihai Railway. North China Transport then designated these Mikana (ミカナ) class.
After the end of the Pacific War, these locomotives were passed on to the Republic of China Railway. After the establishment of the People's Republic of China, China Railways designated them ㄇㄎ17 (MK17) class in 1951, and subsequently 解放17 (JF17) class in 1959. All were retired by 1990.[2]
