The is a Bo′Bo′+Bo′Bo′ wheel arrangement multi-voltage AC two-unit electric locomotive type operated by Japan Freight Railway Company (JR Freight) in Japan hauling freight trains on the Kaikyō Line through the Seikan Tunnel separating mainland Honshu with the northern island of Hokkaido. A prototype locomotive was delivered in January 2013 for evaluation and testing, with full-production locomotives delivered from June 2014, entering service from July 2014.

Background

In order to allow Hokkaido Shinkansen services to operate through the dual-gauge Seikan Tunnel (which commenced on 26 March 2016), the overhead line system voltage was raised from the narrow gauge standard of 20 kV AC to the standard shinkansen power supply of 25 kV AC. A fleet of approximately 20 new dual-voltage locomotives capable of operating under either 20 kV or 25 kV was therefore required to replace the Class ED79 and Class EH500 locomotives previously used to haul freight and overnight sleeping car services through the tunnel.[3] These locomotives are also compatible with the digital ATC and feature digital train wireless communications. The total cost of manufacturing the fleet of locomotives together with construction of new maintenance depot facilities was approximately 19 billion yen.[4] This kind of electric locomotive is modelled on the EH500, which was also manufactured by Toshiba, and therefore has a similar appearance and structure.[5]

Design

The Bo′Bo′+Bo′Bo′ wheel arrangement locomotives are painted in an all-over red livery with a white bodyside line and silver wavy line.[6]

Operations

The locomotives operate between Higashi-Aomori Freight Terminal and Goryōkaku Freight Terminal via the Kaikyō Line and Seikan Tunnel.

History

Design of the prototype locomotive, EH800-901, began in fiscal 2010, and the completed locomotive was unveiled to the press at the Toshiba factory in Fuchū, Tokyo, on 27 November 2012.[7] It was delivered to JR Freight in Sendai in January 2013.[8] Following delivery, the prototype locomotive was tested within the confines of Higashi-Fukushima Station before being moved to Goryōkaku Depot in Hokkaido for testing in winter conditions.[9]

The first full-production locomotive was delivered in June 2014.[10] This entered revenue service on 16 July 2014.[11]

Major overhauls of this train are carried out by the Omiya Comprehensive Vehicle Centre, and traction duties in the DC line area are usually carried out by Class EF210[12] or Class EF65.[13]

Fleet list

, 20 Class EH800 locomotives are in service.[14]
