The Class C59 is a type of 4-6-2 steam locomotive designed by Hideo Shima and built by Japanese National Railways. The C classification indicates three sets of driving wheels. The C59 could haul 17 passenger cars. World War II limited their use as express trains, a function for which they were designed. C59s were transferred to Kyushu after electrification of the trunk lines after the war.^[1] 47 were rebuilt into Class C60 Hudsons between 1953 and 1961 at the railway's Hamamatsu works and Koriyama works. In 1970, the locomotives were retired. Only three are preserved. C59 1 is preserved at the Kyushu Railway History Museum on display. C59 164 is preserved at the Kyoto Railway Museum. C59 161 is preserved at the Hiroshima Children’s Museum.
