The 715 series (715系?) was an electric multiple unit (EMU) train type introduced in February 1984 by Japanese National Railways (JNR), and later operated by East Japan Railway Company (JR East) and Kyushu Railway Company (JR Kyushu) on local services in Japan. They were converted from former 581/583 series sleeping car EMUs.[1]

Operations[edit]

12 4-car 715-0 series sets converted from former 581 series EMU cars were introduced from February 1984 on Nagasaki Main Line and Sasebo Line local services in Kyushu alongside new 713 series EMUs.[1]

15 4-car 715-1000 series sets converted from former 581/583 series EMU cars were introduced from March 1985 on Tōhoku Main Line local services in the Sendai area.[1]

Rebuilding[edit]

The sets were rebuilt from surplus former 581/583 series EMU cars at JNR factories in Tsuchisaki (Akita), Kōriyama (Fukushima), Mattō (Ishikawa), and Kokura (Kitakyūshū). Rebuilding work involved removing the upper sleeper berths, adding longitudinal bench seating at the ends of cars, increasing the number of doorways, reducing the number of toilets and washing areas, and the addition of slab-front cab ends to some former intermediate cars.[1]
