JNR Class EF81
The Class EF81 is a six-axle Bo-Bo-Bo wheel arrangement multi-voltage AC/DC electric locomotive type operated on passenger and freight services in Japan since 1968. As of 1 April 2016[update], 44 locomotives remained in service, operated by JR Freight, JR East, and JR West.
152 locomotives were built from 1968 to 1979 in three batches and numbered EF81 1 to EF81 152. 14 EF81-0 locomotives were later modified to become Class EF81-400. The prototype locomotive, EF81 1, was built by Hitachi, and delivered in 1968. Locomotives EF81 137 onward were built with sun-visor plates above the cab windows. These were also subsequently retro-fitted to locomotives EF81 133 to 136.
The prototype, EF81 1, was withdrawn on 31 March 2004.
From May 2012, JR Freight locomotives not fitted with driving recording units mandated for operations over 100 km/h (60 mph) were renumbered by adding "600" to the running number to differentiate them from the other members of the sub-class fitted.
As of 1 April 2016[update], 18 Class EF81-0 locomotives remained in service, operated by JR East and JR West.
Four locomotives were built between 1973 and 1975 by Hitachi with unpainted corrugated stainless steel bodies for use on services through the undersea Kanmon Tunnel to Kyushu. In 1978, locomotives EF81 301 and 302 were transferred to the Joban Line, and received the standard JNR AC/DC livery of pale red.
As of 1 April 2016[update], only one Class EF81-300 locomotive remained in service, EF81 303, operated by JR Freight and based at Moji Depot.
14 locomotives were built in 1986 and 1987 and to replace ageing Class EF30 hauling services through the Kanmon Tunnel. Although some locomotives operating on a few "Blue Train" services served some railway lines in Kyushu, in particular sections of the Kagoshima Main Line and the Nippō Main Line as well as the entire Nagasaki Main Line.
