JR Kyushu 811 series

Data (as of 6 Jul 2024)

History

The 811 series is a type of suburban train for Kitakyushu and Fukuoka areas. Before the privatisation of Japanese National Railways, stopping services in the areas were mostly provided by dual-voltage trains, as San-yo Main Line (from Moji to the east) is electrified with DC 1.5 kV while the rest of the island is AC 20 kV 60 Hz. However, JR Kyushu concluded that no more dual-voltage trains are necessary, and AC-only EMUs would be much cheaper to introduce and maintain.

Each unit consists of four coaches, and have three sets of doors per carriage with transverse seating. They were used for a few express services at peak seasons until the early-90s so that they are a little more comfortable than other suburban trains. 23 units have been introduced in total. Since 2016, JR Kyushu has been carrying out a major refurbishment programme, and the trains are being converted to commuter trains (longitudinal seating without toilet).

Current Operations & Future Prospects

The 811 series trains are used on Kagoshima Main, Nagasai Main and Nippo Main Lines. They are mostly used on Kagoshima Main Line, and thus very common in Hakata and Kokura areas.
