The are electric multiple unit train types operated by Fukuoka City Transportation Bureau on the Nanakuma Line in Fukuoka, Japan.[2]
The exterior was designed by the German industrial designer Alexander Neumeister.[2] 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.
the 3000 series fleet consists of 21 four-car sets.[3] They are formed as follows with all cars being motored.[4]
| Car No. | 1 | 2 | 3 | 4 | |
|---|---|---|---|---|---|
| Designation | M1c | M1 | M3 | M3c | |
| Numbering | 31xx | 32xx | 35xx | 36xx |
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.
The original 3000 series was introduced on 3 February 2005 on the newly opened Nanakuma Line between and . Unlike the 1000 series and 2000 series trains operated on the Kūkō Line and Hakozaki Line, the 3000 series trains are standard gauge and use linear motor propulsion.[2] [5]
A further four sets were ordered in 2021. These sets, designated as 3000A series, were ordered in anticipation for an increase in service needed when the Nanakuma Line extension from to [6] would open on 27 March 2023.
Externally, these sets distinguished from older sets by their sky-blue and green livery.[7] Internally, the sets' intermediate cars feature sets of "universal design" priority seats that are 490mm high, a 60mm increase over other seats.[8] [9] The Fukuoka City Transportation Bureau reports that the heightened seats are designed to be easier to sit on and stand up from.
The first set was delivered in September 2021,[10] and the 3000A series sets made their first trips in revenue service in February 2022.[11]
Four sets were ordered in 2024 to allow for an increase in frequency from 17 to 21 trains per hour.
