Manchukuo National Railway In 1923, sixteen D50 class locomotives were exported to the
Jichang Jidun Railway in
Manchuria, which designated them class 500 and numbered 501 through 516. Ten were built by Kawasaki (works nos. 970−971, 1140−1170) and six by Kisha Seizō (w/n 965−970), and though very similar to the Japanese D50 class, there were some slight differences in dimensions due to the larger
loading gauge on Chinese lines. After the establishment of
Manchukuo, the Jichang Jidun Railway was nationalised along with other private railways to form the
Manchukuo National Railway. The MNR classified these Mikana (ミカナ) class, numbered 6540−6555, renumbered 501−516 in 1938. After the establishment of the
People's Republic of China, China Railways designated them ㄇㄎ5 (MK5) class in 1951, and subsequently 解放5 (JF5) class in 1959.
Central China Railway In 1939, D50 193 was converted to standard gauge and shipped to the
Central China Railway, where it operated primarily between
Nanjing and
Shanghai. This engine lasted in service on China Railways until 1955.
China Railways After the establishment of the
People's Republic of China, all the railways of China were taken over by the
China Railway, which classified the D50s as ㄇㄎ16 (MK16) class in 1951, later becoming class 解放16(JF16). This class retired 1955. ==Preserved examples==
