JNR Class DD16
JR East DD16 11 in service in May 2009
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).
A total of 65 locomotives were built between 1971 and 1975.
- 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
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. 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).
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.
With the closure of may rural lines and discontinuation of rural freight services in the 1980s, many of the class were withdrawn from operation and scrapped.
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)
