The Class D51 (D51形) is a type of 2-8-2 steam locomotive built by the Japanese Government Railways (JGR), the Japanese National Railways (JNR), and various manufacturers from 1936 to 1945.^[2]

Design and operation

The design of class D51 was based on the earlier D50, introduced in 1923. Wartime production featured some substitution of wood for steel parts like running boards, smoke deflectors and tender coal bunkers. A total of 1,115 D51s were built,^[2] the largest number in any single class in Japan. Early D51s were nicknamed Namekuji-gata ("slug-form") for their shape. The locomotive was designed by Hideo Shima. It was used mainly in freight service through the 1960s. ^[3]

Service outside Japan

Soviet Railways D51

The specially built D51s that were left on Sakhalin (formerly Karafuto) by the retreating Japanese at the end of World War II were used until 1979 by Soviet Railways. One was left outside Yuzhno-Sakhalinsk railway station, and one is in running condition and is kept at the Yuzhno-Sakhalinsk railway station. Additionally two wrecks were left to the north of the city.^[4]

Korean National Railways Mika7

Two locomotives were built for the Korean National Railroad in 1950 by Mitsubishi. Designated Mika7 (미카7) class, they were nearly identical to JNR class D51 except for the gauge.^[5]

Taiwan Railways Administration DT650

From 1936 to 1944, Kawasaki, Kisha Seizō and Hitachi had built 32 D51s for Imperial Taiwan Railway. After World War II, they were taken over by Taiwan Railways Administration, and were classified DT650. In 1951, Kisha Seizō built three DT650s and Mitsubishi Heavy Industries built two DT650s for Taiwan Railways Administration.^[6]

Classification

The classification consists of a "D" for the four sets of driving wheels and the class number 51 for tender locomotives that the numbers 50 through 99 were assigned to under the 1928 locomotive classification rule.

Preserved examples

Over 170 Class D51 locomotives are preserved in Japan. D51 498 was restored by JR East and pulls special-event trains on JR East lines.^[7]

The following is a list of preserved locomotives as of September 2012.^[8]
