Operations

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]

As of 1 March 2017, 25 Class EH200 locomotives are in service (EH200-901 and EH200-1 to EH200-24).[4]
