JNR Class DE10
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, 138 locomotives remained in operation.
JR East DE10 1765 in September 2015
158 DE10-0 locomotives were built with steam heating boilers for passenger use.
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.
