Trains originally operated as 7+4-car formations on Super Hitachi limited express services between Ueno in Tokyo and Sendai via the Jōban Line, but were withdrawn from regular scheduled services from the start of the revised timetable on 16 March 2013. The majority of the fleet was subsequently modified to become the 651-1000 series, and re-employed on Akagi and Kusatsu limited express services from March 2014.
