The Class EH800 (EH800形?) 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[edit]

When Hokkaido Shinkansen services commence operation through the dual-gauge Seikan Tunnel in fiscal 2015, the overhead line system voltage will be raised from the present 20 kV AC to the standard shinkansen power supply of 25 kV AC. A fleet of approximately 20 new dual-voltage locomotives also capable of operating under 25 kV will therefore be required to replace the Class ED79 and Class EH500 locomotives currently used to haul freight and overnight sleeping car services through the tunnel.[2] The new locomotives will also be compatible with the digital ATC and feature digital train wireless communications.[2] The total cost of manufacturing the fleet of locomotives together with construction of new maintenance depot facilities is expected to be approximately 19 billion yen.[3]

Design[edit]

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.[4]

Operations[edit]

The locomotives operate between Higashi-Aomori Freight Terminal and Goryōkaku Freight Terminal via the Kaikyō Line and Seikan Tunnel.[3]

History[edit]

Design of the prototype locomotive, EH800-901, began in fiscal 2010,[3] and the completed locomotive was unveiled to the press at the Toshiba factory in Fuchū, Tokyo, on 27 November 2012.[5] It was delivered to JR Freight in Sendai in January 2013.[6] 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.[7]

The first full-production locomotive was delivered in June 2014.[8] This entered revenue service on 16 July 2014.[9]
