JNR Class DD10

The JNR Class DD10 was a diesel-electric locomotive operated by the Japanese National Railways from 1935 to September 1947.
==History==
The DD10 was an early diesel locomotive operated by the Japanese National Railways. The locomotive was a prototype of a diesel locomotive which could perform switching duties or pull short passenger trains. One locomotive was built by Kawasaki in 1935, designed using data collected from the DC10 and DC11 locomotives. It was numbered DD10 1.
Powered by gasoline, DD10 1 was assigned to Ōyama Rolling Stock Depot and performed switching duties near Ōyama Station. Although its performance was said to be on par with the Class 2120 steam locomotives in use for this purpose, it suffered from problems such as noisy operation and vibrations, making the DD10 a difficult locomotive to work with. The locomotive was sidelined due to wartime restrictions on gasoline and was withdrawn from service in September 1947.
Post-war, DD10 1 was stored at Ōmiya Works; it was scrapped around February 1965.
==Design==
The DD10 featured a boxcab-like design.
==Specifications==
The DD10 was fitted with a Niigata Tekkō K8C inline-8 prime mover and an electric transmission; this prime mover produced about 600 PS (441 kW).
