The 305 series (305系?) is a DC electric multiple unit (EMU) commuter train type operated by Kyushu Railway Company (JR Kyushu) on Chikuhi Line and Fukuoka Subway Kuko Line through-running services in Kyushu, Japan, since 5 February 2015.[1] The entire fleet of six six-car sets (36 vehicles) is scheduled to be in service by the start of the 14 March 2015 timetable revision.[2]

Design
The fleet of 36 vehicles (six six-car sets) will be built by Hitachi at a cost of approximately 5.7 billion yen, with styling overseen by industrial designer Eiji Mitooka.[3] The new trains are designed to offer improved universal accessibility.[4] Fully enclosed permanent-magnet synchronous motors (PMSM) are used to reduce environmental noise and reduce power consumption by approximately 57% compared with existing 103 series trains.[2]
Operations
The 305 series trains are used on through services between Nishi-Karatsu the Chikuhi Line and Fukuokakūkō on the Fukuoka Subway Kuko Line, replacing older 103-1500 series sets.[1][3]
Formations
The 305 series trains are formed as six-car sets as shown below, numbered W1 to W6, consisting of four motored intermediate cars and two non-powered driving trailer cars.[5] Car 1 is at the Nishi-Karatsu end.[5]
| Car No. | 1 | 2 | 3 | 4 | 5 | 6 |
|---|---|---|---|---|---|---|
| Designation | Tc | M | Mp | M1 | M1p | T'c |
| Numbering | KuHa 305 | MoHa 305 | MoHa 304 | MoHa 305-100 | MoHa 304-100 | KuHa 304 |
| Weight (t) | 29.5 | 33.0 | 30.8 | 33.0 | 30.7 | 27.3 |
| Capacity (total/seated) | 128/42 | 147/51 | 147/51 | 147/51 | 147/51 | 135/45 |
Cars 3 and 5 each have two PS402K single-arm pantographs.[5]
Interior
Passenger accommodation consists of longitudinal bench seating with space for wheelchairs or strollers in each car.[4] Each row of seats has a different seat cover design.[2] Large liquid-crystal display screens are used for providing passenger information, and LED lighting is used throughout.[4] Car 1 features wooden flooring of the same design as that used in JR Kyushu's luxury cruising train Seven Stars in Kyushu.[2] Car 1 also has a universal access toilet.[1] The side doors are equipped with passenger-operated open/close buttons, and these are normally available for use between Misakigaoka and Nishi-Karatsu stations on the Chikuhi Line.[2]
