EF81-600: Former EF81-0 locomotives renumbered by JR Freight from May 2012
EF81-0
152 locomotives were built from 1968 to 1979 in three batches and numbered EF81 1 to EF81 152.[2] 14 EF81-0 locomotives were later modified to become Class EF81-400.[2] The prototype locomotive, EF81 1, was built by Hitachi, and delivered in 1968.[1] Locomotives EF81 137 onward were built with sun-visor plates above the cab windows.[4] These were also subsequently retro-fitted to locomotives EF81 133 to 136.[4]
The prototype, EF81 1, was withdrawn on 31 March 2004.[2]
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.[4]
As of 1 April 2016[update], 18 Class EF81-0 locomotives remained in service, operated by JR East and JR West.[3]
EF81 2 (first batch) with white stripes indicating refurbishment in March 2008

EF81-300
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.[2] In 1978, locomotives EF81 301 and 302 were transferred to the Joban Line, and received the standard JNR AC/DC livery of pale red.[1]
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.[3]

Locomotives EF81 409 to 414 were withdrawn between March 1996 and December 2010.[5]
As of 1 April 2016[update], three Class EF81-400 locomotives remained in service, EF81 403/404/406, all operated by JR Freight and based at Moji Depot.[3]

As of 1 April 2016[update], 14 Class EF81-600 locomotives remained in service, operated by JR Freight and based at Moji and Toyama Depots.[3]
