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, 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.

EH200-0 full-production version

Following evaluation of the prototype version, the first full-production locomotive, EH200-1, was delivered to Takasaki in March 2003.[2] A number of minor improvements were incorporated, with the main external differences from the prototype being as follows.[2]

Elimination of centre pillar in the cab windscreens

gollark: You can handle resources nicely with function calls by having getThing or setThing or whatever, you can't do it the other way round.

gollark: I like the statelessness thing, but not the resource-oriented thing.

gollark: Also also, people cannot actually agree on what it is and what it means you should do half the time.

gollark: Also, people often want to do things like "restart" in their API, which it can't nicely express, and end up contorting it horribly.
