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) was 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]

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]

History

The first set, numbered W1, was delivered from the manufacturer Hitachi in Kudamatsu, Yamaguchi to JR Kyushu's Kokura Depot in November 2014,[6] and moved to Karatsu Depot in December 2014.[7]

A special public preview run was held on 31 January 2015, ahead of the formal entry into service on 5 February.[8]
