The Class EF200 (EF200形) is a Bo-Bo-Bo wheel arrangement DC electric locomotive operated by JR Freight on freight services in Japan since 1992.[1]

Overview

The Class EF200 was developed to replace Class EF66 electric locomotives on heavy freight services on the Tokaido Main Line and Sanyo Main Line west of Tokyo.[1] It is equipped with six 1,000 kW (1,300 hp) FMT2 traction motors, giving a total power output of 6,000 kW (8,000 hp).[1] Ultimately, the class was deemed to be over-specified and unnecessarily expensive, and the order was terminated after the delivery of 20 full-production locomotives.[2] The subsequent Class EF210 was instead chosen as the standard design for hauling freight services on the Tokaido Main Line and Sanyo Main Line.[2] Originally designed to haul 1,600 t freight trains, problems of insufficient power supply capacity to the overhead lines, meant that the class was initially limited to hauling 1,200 t trains.[3]

Operations

As of 1 April 2016, the fleet consists of 12 locomotives (EF200-2 – 7, 10, 15, and 17 – 20), based at Suita Depot in Osaka.[4] They are used primarily on 1,300 t freight trains west of Tokyo on the Tokaido and Sanyo Main Lines.[3]

History

EF200-4 in original livery, December 2006

The prototype locomotive, EF200-901, was delivered in March 1990 for extensive testing.[3] The first full-production locomotives were delivered to Shin-Tsurumi Depot in Tokyo in 1992, entering revenue service on the Tokaido Main Line and Sanyo Main Line from the summer of that year.[1] In 1992, the Class EF200 was awarded the Laurel Prize, presented annually by the Japan Railfan Club.[5]

From 1 April 1999, the entire class was transferred from Shin-Tsurumi in Tokyo to Suita Depot in Osaka.[3] Between 2006 and 2009, the entire fleet was repainted into a new livery similar to that used for the later Class EF210 locomotives.[6] EF200-901 was repainted in 2007.[1]

From 2007, the class was power-derated to match the power output of the older Class EF66 locomotives.[2] In 2011, one class member, EF200-1, was withdrawn.[2]

During fiscal 2015, eight members of the class were removed from regular duties, leaving 12 members in service.[7]

Preserved examples

The prototype locomotive, EF200-901, was moved to the Hitachi factory in Mito, Ibaraki, in October 2016 for preservation.[8]
