The is a Bo′Bo′+Bo′Bo′ wheel arrangement twin unit DC electric freight locomotive operated by JR Freight in Japan since 2001.[1] [2]
The locomotives are built at the Toshiba factory in Fuchū, Tokyo. They are all based at Takasaki depot, and are primarily used on oil tank trains north of Tokyo and on the steeply-graded Chūō Main Line, Shinonoi Line, and Joetsu Line, replacing pairs of Class EF64s.[3]
, 25 Class EH200 locomotives are in service (EH200-901 and EH200-1 to EH200-24).[4]
The pre-production prototype, EH200-901, was delivered to Takasaki depot in 2001, and entered revenue service in October 2002 following extensive testing.
Following evaluation of the prototype version, the first full-production locomotive, EH200-1, was delivered to Takasaki in March 2003. A number of minor improvements were incorporated, with the main external differences from the prototype being as follows.
See main article: Japan Railways locomotive numbering and classification.
The EH200 classification for this locomotive type is explained below. As with previous locomotive designs, the prototype is numbered EH200-901, with subsequent production locomotives numbered from EH200-1 onward.
