The Class EH200 (EH200形) is a Bo′Bo′+Bo′Bo′ wheel arrangement twin unit DC electric freight locomotive operated by JR Freight in Japan since 2001.[1][2]

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

Variants

  • EH200-900: Prototype locomotive EH200-901, built 2001
  • EH200-0: Full-production locomotives built from 2003 onward

EH200-901 prototype

The pre-production prototype, EH200-901, was delivered to Takasaki depot in 2001, and entered revenue service in October 2002 following extensive testing.
