The Class DD16 (DD16形) is a four-axle Bo-Bo wheel arrangement diesel-hydraulic locomotive type operated in Japan since 1972. A total of 65 locomotives were built between 1971 and 1975, and as of 1 April 2016^[update], one locomotive remains in service, operated by East Japan Railway Company (JR East).

Variants

A total of 65 locomotives were built between 1971 and 1975.^[1]

Class DD16-0: 65 locomotives built between 1971 and 1975
Class DD16-300: 4 locomotives converted from DD16-0 locomotives between 1979 and 1983 to become self-propelled snowplough units^[2]

Design

The Class DD16 was designed to replace the Class C12 and C56 steam locomotives on non-electrified rural lines where locomotives with a low axle load were required.^[2] The design featured an offset centre-cab arrangement using the same DML61Z diesel engine used in the Class DD51 locomotives, derated from 1,000 hp (750 kW) to 800 hp (600 kW).^[2]

History

The first two locomotives, DD16 1 and 2, were built at the Japanese National Railways (JNR) Nagano factory, and these were tested on the Koumi Line and Iida Line.^[1]

Between 1979 and 1983, four locomotives (DD16 2, 5, 4, and 13) were converted at JNR's Nagano and Matto workshops to become self-propelled snowplough units, numbered DD16 301 to 304, with the addition of bogie snowplough units on either end.^[3]

Snowplough unit DD16 303 in service on the Oito Line in February 1991

With the closure of many rural lines and discontinuation of rural freight services in the 1980s, many of the class were withdrawn from operation and scrapped.^[1]

With the privatization of JNR in April 1987, just ten Class DD16 locomotives remained in service, transferred to operation by JR Group operating companies.^[4]

By 1 April 1995, seven locomotives were still in service, with four (DD16-0 and DD16-300) operated by East Japan Railway Company (JR East), two (DD16-0) operated by Kyushu Railway Company (JR Kyushu), and one (DD16-300) operated by West Japan Railway Company (JR West).^[3]

JR East DD16 20 in October 1999 at Omiya Works, where it was used as a works shunter, repainted in "Hokutosei" blue livery
JR East DD16 36 in August 1994 at Omiya Works, where it was used as a works shunter, repainted in "Hokutosei" maroon livery
JR Kyushu DD16 62 at Kagoshima Depot in August 1998

As of 1 April 2016^[update], one locomotive, DD16 11, remains in service, operated by JR East.^[5]
