817 series


The 817 series is an AC electric multiple unit train type operated on commuter and local services by Kyushu Railway Company 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.
31 two-car sets 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 second-batch 817-1000 series two-car sets 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 three-cars sets in the future if needed. A further two third-batch sets were added in February 2005.

Experimental battery EMU set

In March 2013, JR Kyushu converted two-car 817-1000 series set VG114 to a battery electric multiple unit by adding lithium-ion storage batteries to enable the train to run on non-electrified lines. The train has a maximum speed of when running off the 20 kV AC overhead power supply of electrified lines, and when running on battery power over non-electrified lines. It can run a distance of up to on battery power. The train was tested on non-electrified lines from September 2013.

817-1100 series

Four fourth-batch two-car 817-1100 series sets 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.
