EF64-1000 Subclass
The first EF64-1000, EF64 1001, appeared in 1980 for use on the Jōetsu Line, replacing ageing EF15/16 and EF58 locomotives. This subclass could almost be described as a totally new design. The body was lengthened from 17,900 mm to 18,600, and the bodysides were given an asymmetrical appearance with ventilation grilles at one end and windows at the other. PS22 scissors-type pantographs replaced the PS17 lozenge-type pantographs of the EF64-0s. The bogies were the same DT138A/DT139A type as used on EF81 locomotives. A total of 53 EF64-1000s were built by 1982, all by Kawasaki and Tōyō Electric. Locos from EF64 1033 onward were built without train-heating generators.
Apart from a handful of locos owned by JR East and based at Takasaki and Nagaoka depots for use on sleeper and charter train haulage, the subclass is largely based at Takasaki for Jōetsu Line freight duties. Locos EF64 1046 to 1050, however, are based at Okayama depot for use on Hakubi Line freight duties.
EF64 1030 and 1031, owned by JR East, both have EMU-couplers and jumper sockets, and these locos are frequently used for hauling new rolling stock from the Niitsu factory to Tōkyō via the Jōetsu Line, and also for hauling withdrawn rolling stock to Nagano.
