The 251 series (Japanese: 251系) was a DC electric multiple unit (EMU) train type operated by East Japan Railway Company (JR East) on Tokaido Main Line Super View Odoriko limited express services in Japan between April 1990[1] and March 2020.

Operations[]

The 251 series sets were primarily used on Super View Odoriko limited express services from Tokyo, Ikebukuro, and Shinjuku to Izukyu Shimoda.[2]

Since the 13 March 2004 timetable revision, 251 series sets were also used on the weekday morning Ohayō Liner Shinjuku 26 and weekday evening Home Liner Odawara 23 services.[2]

Formation[]

The four sets, numbered RE1 to RE4 and based at Ōmiya Depot in Tokyo, were formed as follows, with car 1 at the Izukyū-Shimoda end, and car 10 at the Tokyo and Shinjuku end.[2]

History[]

Set RE2 in original livery in April 2003

Built by Kawasaki Heavy Industries and Kinki Sharyo,[3] the first two sets were introduced from 28 April 1990.[4] These were followed by two more sets in 1992.[1]

The 251 series was awarded the 1991 Laurel Prize, presented annually by the Japan Railfan Club.[5] A formal presentation ceremony was held at Shinagawa Station in Tokyo on 1 March 1992.[6]

The fleet underwent a programme of refurbishment between December 2002 and March 2004, which included the addition of new seating, and repainting the sets into a new colour scheme.[2]

Withdrawal[]

From the start of the revised timetable on 14 March 2020, the 251 series sets were replaced by new E261 series sets on services between Tokyo and Izukyu-Shimoda, with the Super View Odoriko brand being replaced by new ultra-deluxe Saphir Odoriko services. The last 251 series Super View Odoriko limited express run took place on 13 March 2020.
