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. The entire fleet of six six-car sets (36 vehicles) was scheduled to be in service by the start of the 14 March 2015 timetable revision.
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. The new trains are designed to offer improved universal accessibility. 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.
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. Car 1 is at the Nishi-Karatsu end.
|Numbering||KuHa 305||MoHa 305||MoHa 304||MoHa 305-100||MoHa 304-100||KuHa 304|
Passenger accommodation consists of longitudinal bench seating with space for wheelchairs or strollers in each car. Each row of seats has a different seat cover design. Large liquid-crystal display screens are used for providing passenger information, and LED lighting is used throughout. Car 1 features wooden flooring of the same design as that used in JR Kyushu's luxury cruising train Seven Stars in Kyushu. Car 1 also has a universal access toilet. 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.
A special public preview run was held on 31 January 2015, ahead of the formal entry into service on 5 February.
