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 (ミカナ) class.^{[citation needed]} Those that were delivered to the Zhegan Railway were operated by the Central China Railway during the Japanese occupation.
