JNR Class Ke DB10

The JNR Class Ke DB10 was a Japanese very-narrow gauge diesel-mechanical locomotive operated by the Japanese National Railways from 1935 to May 1942.

History[]

Ke DB10 was originally built around 1932 by the Whitcomb Locomotive Company for the Miyazaki Prefectural Electric Railway; it was originally numbered 1. In Whitcomb's catalog, the locomotive was designated "Type MV".

When the Miyazaki Prefectural Electric Railway was acquired by the JNR in 1935, 1 was renumbered Ke DB10. Ke DB10 was struck from the register in May 1942, although it was likely only used until around October 1941 when the sections of track the locomotive was used on were converted to 3 ft 6 in gauge (1,067 mm) track; any further details regarding the locomotive's service history are not known.

Specifications[]

Ke DB10 was powered by a Waukesha V4 engine which made about 45 horsepower (33.6 kW). This was mated to a 4-speed mechanical transmission.
