Variants
DE10-0 subclass
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.
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 JNR 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.
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 subclass
JR Freight shunting locomotives rebuilt from 2009 from former JR East Class DE15 snow-plough locomotives.
