JNR Class DC10

The JNR Class DC10 was a diesel-mechanical locomotive operated by the Japanese National Railways from 1930 to 1935.
==History==
The DC10 was an early diesel locomotive operated by the Japanese National Railways. The locomotive was imported as an example of a switcher diesel locomotive alongside the DC11 for a trial period. One locomotive, DC10 1, was manufactured by Krupp in 1930 but was apparently significantly delayed; the locomotive arrived at Kobe Port in November 1930, where it was disassembled and inspected before being assembled again at Takatori Works.
After performance testing on the San'yō Main Line, DC10 1 was assigned to Takatori Rolling Stock Depot where it performed switching duties at Kobe Port and various other locations. Being designed during a period where technology used in the locomotive was still being researched and developed, many design defects were present and the locomotive was withdrawn from service in 1935, with many failures having occurred. An inability to procure or manufacture parts of sufficient quality led to DC10 1 being scrapped as there was no way to maintain the locomotive. The various parts from DC10 1 would be analyzed after its scrapping, with the data obtained from these used to develop internal combustion locomotive engines in Japan.
This was the only JNR locomotive manufactured by Krupp.
==Design==
The DC10 featured a boxcab design.
==Specifications==
The DC10 was fitted with a Krupp inline-6 prime mover and a Krupp mechanical transmission; this prime mover produced about 600 PS (441 kW). It had a drive system similar to a steam locomotive, featuring a set of jackshafts.
