The China Railways JF12 (解放12, Jiěfàng, "liberation") class steam locomotive was a class of 2-8-2 steam locomotives operated by the China Railway, built by the ALCo in the United States in 1922.

[citation needed] After the Japanese established the puppet Provisional Government of the Republic of China, this and other privately owned railways in the territory of the collaborationist government were merged in 1938 to form the North China Transportation Company to manage all railway and bus transportation in the territory.

As a subsidiary of the South Manchuria Railway, North China Transport used the same classification system for locomotives as the SMR did, under which these engines were designated Mikana (シカナ) class.

[citation needed] After the end of the Pacific War, thirty of these locomotives were passed on to the Republic of China Railway.

[citation needed] JF12 3822, 3832−3834, and 3838 were noted to be in dump around Lanzhou, Hohhot, Baotou and other places in October 1985.
