The 711 series (711系, 711-kei) was an ACelectric multiple unit (EMU) train type operated by Hokkaido Railway Company (JR Hokkaido) on Sapporo area suburban services in Hokkaido, Japan, from 1968 until March 2015. It was the first AC EMU train to be operated in Japan by the former Japanese National Railways (JNR).[1] The last remaining trains in service were withdrawn on 13 March 2015.[2]

History
Prototype sets
Former prototype set S901 leading a 6-car formation at Sapporo, 1994
Two prototype two-car sets, numbered KuMoHa 711-901 + KuHa 711-901 and KuMoHa 711-902 + KuHa 711-902, were delivered in February 1967 for test running ahead of the start of electric suburban services between Otaru and Takikawa from 1968. Both sets were based on the KiHa 22 diesel multiple unit design, but set 901 had opening two-pane windows and featured two sets of four-leaf folding doors per side, whereas set 902 had sealed double-glazed windows, as used on the subsequent full-production sets. The two sets were modified to full-production standards in 1968 and 1970, but set 901 retained its opening windows.[6]
Full-production sets
The first full-production three-car sets were delivered from August 1968.[1] A third, centre, door was added to some of the KuHa 711 cars from 1987.[1] All cars became no-smoking from 1 July 1992.[4] Priority seating was added from 1 October 1997.[4] Air conditioning was added to the two-door sets between 2001 and 2002.[4] The original scissors-type pantographs were replaced with N-PS785 single-arm pantographs between 2004 and 2005.[4]
