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.[3] The subsequent Class EF210 was instead chosen as the standard design for hauling freight services on the Tokaido Main Line and Sanyo Main Line.[3] Originally designed to haul 1,600-tonne (1,575-long-ton; 1,764-short-ton) freight trains, problems of insufficient power supply capacity to the overhead lines, meant that the class was initially limited to hauling 1,200-tonne (1,181-long-ton; 1,323-short-ton) trains.[4]

Operations
As of 1 April 2016[update], the fleet consists of 12 locomotives (EF200-2 – 7, 10, 15, and 17 – 20), based at Suita Depot in Osaka.[5] They are used primarily on 1,300 t freight trains west of Tokyo on the Tokaido and Sanyo Main Lines.[4]
Variants
- EF200-900: Prototype locomotive EF200-901, built 1990
- EF200-0: Full-production locomotives EF200-1 – 20, built 1992–1993
History

Perspective
The prototype locomotive, EF200-901, was delivered in March 1990 for extensive testing.[4] 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.[6]
From 1 April 1999, the entire class was transferred from Shin-Tsurumi in Tokyo to Suita Depot in Osaka.[4] Between 2006 and 2009, the entire fleet was repainted into a new livery similar to that used for the later Class EF210 locomotives.[7] EF200-901 was similarly repainted in 2007.[1]
From 2007, the class was power-derated to match the power output of the older Class EF66 locomotives.[3] In 2011, one class member, EF200-1, was withdrawn.[3]
During fiscal 2015, eight members of the class were removed from regular duties, leaving 12 members in service.[8] The final service of the Class EF200 took place on 28 March 2019, as EF200-18 hauled its last freight train from the Hatabu yard in Shimonoseki to the Suita freight terminal in Osaka.[2]
