The 817 series is an AC electric multiple unit (EMU) train type operated on commuter and local services by Kyushu Railway Company (JR Kyushu) in Japan since 2001. The design was based on the earlier 815 series, with transverse seating replacing the previous longitudinal seating, although later variants reverted to longitudinal seating.

Variants

There are five sub-series variants, 817-0, 817-1000, 817-1100, 817-2000, and 817-3000 series, allocated to five depots, Kagoshima, Kumamoto, Minami-Fukuoka, Nagasaki, and Nōgata. The trains carry large colour-coded stickers next to the passenger doors according to the depot.

  •      Kagoshima (817-0 series): Blue
  •      Kumamoto (817-0 series): Green
  •      Minami-Fukuoka (817-3000 series): Orange
  •      Nagasaki (817-0 series): Red
  •      Nōgata (817-1000, 817-1100, 817-2000 series): Yellow
  • 817-0 series

    31 2-car sets (V001 to V031) were delivered to Minami-Fukuoka and Nōgata depots between August September 2001 for use on the newly electrified Fukuhoku Yutaka Line, Nagasaki Main Line, and Sasebo Line.

    The 31 sets were later reallocated to Kagoshima, Kumamoto, and Nagasaki depots from 2003 following the arrival of 817-1000 series sets.

    817-1000 series

    12 2nd-batch 817-1000 series 2-car sets (V101 to V112) were delivered to Nōgata depot between August and September 2003, displacing the earlier 817-0 series sets based there. These sets were designed to be able to be lengthened easily to 3-cars sets in the future if needed. A further two 3rd-batch sets (V113 and V114) were added in February 2005.

    Experimental battery EMU set

    In March 2013, JR Kyushu converted 2-car 817-1000 series set VG114 to a battery electric multiple unit (BEMU) by adding lithium-ion storage batteries to enable the train to run on non-electrified lines. The train has a maximum speed of 120 km/h (75 mph) when running off the 20 kV AC overhead power supply of electrified lines, and 80 km/h (50 mph) when running on battery power over non-electrified lines. It can run a distance of up to 30 km (20 mi) on battery power. The train was tested on non-electrified lines from September 2013.

    817-1100 series

    Four 4th-batch 2-car 817-1100 series sets (V1101 to V1104) were delivered to Nōgata depot in March 2007 to provide increased capacity on the Fukuhoku Yutaka Line. These were based on the earlier 817-1000 series, but with larger LED destination indicators on the cab ends.

    Formation

    As of 1 April 2013, the fleet consists of four 2-car 817-1100 sets (V1101 to V1104), all based at Nōgata Depot, and formed as shown below.

These sets have white-painted bodysides, and feature longitudinal seating to provide increased overall capacity and relieve overcrowding on the line. These sets feature interior LED lighting. They operate at a maximum speed of 100 km/h, although they have a maximum design speed of 120 km/h. A seventh set, V2007, was delivered in February 2013.
