The E657 series (E657系) is an AC/DC dual-voltage electric multiple unit (EMU) train type operated by East Japan Railway Company (JR East) in Japan on limited express services between Ueno in Tokyo and Iwaki on the Joban Line since March 2012.[1]
The trains replaced the 651 series and E653 series EMUs previously used on Super Hitachi and Fresh Hitachi limited express services on the Joban Line. The first train in revenue service ran on 3 March 2012, in the form of a special return Super Hitachi limited express service between Ueno and Iwaki, with regular scheduled services starting from the revised timetable on 17 March 2012.[2] The initial order of sixteen 10-car sets was in service by the start of the revised timetable on 16 March 2013.
