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.
