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 used on through services between Nishi-Karatsu the Chikuhi Line and Fukuokakūkō on the Fukuoka Subway Kuko Line, replacing older 103-1500 series sets.
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.
Cars 3 and 5 each have two PS402K single-arm pantographs.
