Japanese electric multiple unit train type From Wikipedia, the free encyclopedia
The 817 series (817系) 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,[2] although later variants reverted to longitudinal seating.

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.[3][4]
31 two-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.[1]
The 31 sets were later reallocated to Kagoshima, Kumamoto, and Nagasaki depots from 2003 following the arrival of 817-1000 series sets.[3]
In fiscal 2020, set V004's transverse seating was replaced with longitudinal seating. It was given the classification 817-500 series and renumbered V504.[5]
| Numbering | KuMoHa 817 | KuHa 816 |

| Capacity total/seated |
131/50 | 127/40 |
The KuMoHa 817 car is fitted with a PS401K single-arm pantograph.[6]
Seating is arranged in a transverse configuration, with flip-over seat backs to face the direction of travel. The KuHa 816 car has a toilet and a wheelchair space.[6]
12 second-batch 817-1000 series two-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 three-cars sets in the future if needed.[3] A further two third-batch sets (V113 and V114) were added in February 2005.[6]
In 2022, set V109's transverse seating was replaced with longitudinal seating. It was given the classification 817-1500 series and renumbered V1509.[7]

As with the 817-0 series, seating is arranged in a transverse configuration, with flip-over seat backs to face the direction of travel. The KuHa 816 car has a toilet and a wheelchair space.[6]
In March 2013, JR Kyushu converted two-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.[8] 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.[8] It can run a distance of up to 30 km (20 mi) on battery power.[8] The train was tested on non-electrified lines from September 2013.[9]
Four fourth-batch two-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.[3]
As of 1 October 2017[update], the fleet consists of four two-car 817-1100 sets (V1101 to V1104), all based at Nōgata Depot, and formed as shown below.[10]

Six fifth-batch 817-2000 series two-car sets (V2001 to V2006) were delivered to Nōgata Depot from January 2012 for introduction on the Fukuhoku Yutaka Line from the start of the revised timetable on 17 March 2012.[4][11] 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.[4] A seventh set, V2007, was delivered in February 2013.[12]
As of 1 October 2017[update], the fleet consists of seven two-car 817-2000 sets (V2001 to V2007), all based at Nōgata Depot, and formed as shown below.[12]
