Design
The exterior was designed by the German industrial designer Alexander Neumeister.[1] Each side of the cars is equipped with three pairs of doors. The bodyside is white with a small light-green line which runs from the front along the top of the windows. This represents the ridge of Mount Abura (located in Jōnan-ku, Sawara-ku and Minami-ku, Fukuoka). Muromi River (located in Nishi-ku and Sawara-ku, Fukuoka) is represented by a light blue stripe along the bottom of the train. There is an emergency door at each end of the train.
Train interior
Equipment
Trainsets consist of four cars, all motored. The trains are equipped with ATO and can be operated unmanned, but driver-only operation is used. The trains use Insulated-gate bipolar transistor (IGBT), a variable-frequency drive system, and LED train destination indicator panels. All cars are air-conditioned.
History
The 3000 series was introduced on 3 February 2005 on the newly opened Nanakuma Line between Tenjin-Minami and Hashimoto. Unlike the 1000 series and 2000 series trains operated on the Kūkō Line and Hakozaki Line, the 3000 series trains are standard gauge (1,435 mm (4 ft 8+1⁄2 in)) and use linear motor propulsion.[1]
A further four sets were ordered in 2021. These sets, designated as 3000A series, will feature a blue and green livery and are intended for an increase in service when the Nanakuma Line is extended from Tenjin-Minami to Hakata, scheduled to open in 2022.[2]
