JR Freight Class EF200
EF200-14 in revised livery, May 2009
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. 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). 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. The subsequent Class EF210 was instead chosen as the standard design for hauling freight services on the Tokaido Main Line and Sanyo Main Line. 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.
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. They are used primarily on 1,300 t freight trains west of Tokyo on the Tokaido and Sanyo Main Lines.
- EF200-900: Prototype locomotive EF200-901, built 1990
- EF200-0: Full-production locomotives EF200-1 – 20, built 1992–1993
The prototype locomotive, EF200-901, was delivered in March 1990 for extensive testing. 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. In 1992, the Class EF200 was awarded the Laurel Prize, presented annually by the Japan Railfan Club.
From 1 April 1999, the entire class was transferred from Shin-Tsurumi in Tokyo to Suita Depot in Osaka. Between 2006 and 2009, the entire fleet was repainted into a new livery similar to that used for the later Class EF210 locomotives. EF200-901 was repainted in 2007.
During fiscal 2015, eight members of the class were removed from regular duties, leaving 12 members in service.
