The Fukuoka Subway 3000 series (福岡市交通局3000系) is an electric multiple unit operated by Fukuoka City Transportation Bureau on the Nanakuma Line in Fukuoka, Japan.^[1]

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]
