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.^[1] As of 1 April 2016^[update], 138 locomotives remained in operation.^[2]

Variants

DE10-0 subclass

158 DE10-0 locomotives were built with steam heating boilers for passenger use.^{[citation needed]}

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.^{[citation needed]}

DE10-500 subclass

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.

DE10-900 subclass

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.

DE10-1000 subclass

210 DE10-1000 locomotives were built from 1969 with steam heating boilers and uprated DML61ZB engines offering 1,350 hp (1,005 kW).

DE10-1500 subclass

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.

DE10-3000/3500 subclass

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.^[3]
