The JNR Class ED76 is a Japanese AC electric locomotive operated by the Japanese National Railways and its successor companies since 1965.
History[]
The ED76 was designed as a versatile AC electric locomotive for use on the JNR. The locomotive was introduced as an improvement on the ED73 locomotives which had been used in Kyushu for some time.
From 1965 to 1979, 139 locomotives were manufactured based on the ED75, the de facto AC electric locomotive in use at the time. The locomotives were split into two subseries; the -0 subseries for use in Kyushu and the -500 subseries for use in Hokkaido, the latter being developed in 1968. In Kyushu, the locomotives were used to pull passenger trains thanks to their SG3B-S steam generators; these locomotives also replaced the older ED72 and ED73 locomotives in Blue Train operations. In Hokkaido, the locomotives pulled both freight and passenger trains and were mainly used on the Hakodate Main Line.
Withdrawals commenced in the 1980s; by the JNR's privatization and division in 1987 nearly half the locomotives had been withdrawn from service. JR Kyushu, JR Hokkaido and JR Freight inherited ownership of the remaining ED76s, with JR Kyushu receiving the bulk of the locomotives, with a total of 36 locomotives. JR Hokkaido retired their locomotives on 31 March 2001, while JR Kyushu retired their locomotives in November 2012. Ten locomotives remain in service, all with JR Freight. One locomotive has been preserved; one additional locomotive, ED76 91, was preserved in the past but has since been scrapped.
Design[]
The ED76s featured large box-shaped bodies with dual large circular headlights mounted on the top of the cars.
Specifications[]
The ED76s used a nose suspension drive system with MT52 traction motors; the use of the nose suspension drive was due to maintenance problems involving the Quill drive, so all locomotives after the earlier EF70 would use the nose suspension drive. This however came at the cost of keeping the rated rotation speed of the traction motors low.
