The China Railways JF11 (解æ¾11, JiÃÂfàng, "liberation") class steam locomotive was a class of "Mikado" type steam locomotives operated by the China Railway.
Originally built for the Jinpu Railway and the Zhegan Railway by ALCO and the Baldwin Locomotive Works in the United States in 1918âÂÂ1937. The Jinpu Railway designated these MK class, received two deliveries, with the first 30 arriving from ALCo between 1918 and 1920. From 1938 to 1945 they were operated by the North China Transportation Company, which grouped them in the Mikana (ãÂÂã«ãÂÂ) class. Those that were delivered to the Zhegan Railway were operated by the Central China Railway during the Japanese occupation.
