JR East DE10 1765 in September 2015
The Class DE10 (DE10形) is a class of Japanese C-B wheel arrangement diesel-hydraulic locomotives. 708 locomotives were built between 1966 and 1978. As of 1 April 2016 [update] , 138 locomotives remained in operation.
158 DE10-0 locomotives were built with steam heating boilers for passenger use.
None of this subclass remains in use on JR, but several examples operate on private railways. DE10 1 is preserved at JR Shikoku's Tadotsu depot.
74 DE10-500 locomotives were built from 1968 with concrete ballast in place of the steam heating boilers for freight use. None of this subclass remains in use on JR, but several examples operate on private railways.
One prototype locomotive, DE10 901, was built in 1967 as a heavy shunting locomotive with ballasting increasing the weight to 70 tonnes. This formed the basis for the Class DE11 design.
210 DE10-1000 locomotives were built from 1969 with steam heating boilers and uprated DML61ZB engines offering 1,350 hp.
265 DE10-1500 locomotives were built from 1969 with uprated DML61ZB engines and concrete ballast in place of the steam heating boilers for freight use.
JR Freight shunting locomotives rebuilt in 2009 from former JR East Class DE15 snow-plough locomotives. The conversion histories and former identities of this sub-class are as follows.

The DE10 classification for this locomotive type is explained below.
The Class EF57 (EF57形) of 2-C+C-2 wheel arrangement DC electric locomotives was a development of the previous JNR Class EF56. 15 Class EF57s were built between 1939 and 1943 by Hitachi and Kawasaki.
The Class DD51 (DD51形) is a B-2-B wheel arrangement diesel-hydraulic locomotive type operated in Japan since 1962. 649 locomotives were built between 1962 and 1978 by Kawasaki Sharyo, Hitachi, and Mitsubishi. The class was designed for mainline passenger and freight use with more power than the D51 and a higher maximum speed than the C62 steam locomotive classes. This was achieved by installing two 1,100 hp engines in an 18 metre long centre-cab design, unusual for mainline operation. The V12 DML61 engines were developed from the 6-cylinder inline DMF31 engines used in the Class DD13 locomotives. As of 1 April 2016, 29 locomotives remained in operation.
The Class EF64 (EF64形) is a 6-axle DC electric locomotive type operated on passenger and freight services in Japan since 1964.
The Class E31 is a class of DC Bo-Bo wheel arrangement electric locomotives formerly operated by the private railway operator Seibu Railway in Japan until March 2010 and subsequently by the Ōigawa Railway.
The EH10 class of electric locomotives were Bo′Bo′+Bo′Bo′ wheel arrangement two-unit DC freight locomotives operated by Japanese National Railways (JNR) in Japan from 1954 until 1982.
The Class EF65 (EF65形) is a 6-axle DC electric locomotive type operated on passenger and freight services in Japan since 1965. A total of 308 locomotives were built between 1965 and 1979, with 52 still in service as of 1 April 2016.
The Class EF81 is a six-axle Bo-Bo-Bo wheel arrangement multi-voltage AC/DC electric locomotive type operated on passenger and freight services in Japan since 1968. As of 1 April 2016, 44 locomotives remained in service, operated by JR Freight, JR East, and JR West.
