The 303 series (303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 22 January 2000.[1]

Design

[edit]

The 303 series trains were designed to augment the 103-1500 series EMUs used on the Chikuhi Line, coinciding with double-tracking of the section between Shimoyamato and Chikuzen-Maebaru.[2] The trains have lightweight stainless bodies with painted steel cab ends.[2]

Operations

[edit]

The 303 series trains are used on through services between Nishi-Karatsu the Chikuhi Line and Fukuokakūkō on the Fukuoka Subway Kuko Line.[3] They are compatible with automatic train operation (ATO) used on the Fukuoka Subway tracks, and are also equipped for wanman driver only operation.[2]

Formations

[edit]

The fleet consists of three six-car sets, numbered K01 to K03 and based at Karatsu Depot. The sets are formed as shown below with four motored ("M") intermediate cars and non-powered driving trailer ("Tc") cars, with car 1 at the Nishi-Karatsu end.[2][3]

[edit]

Passenger accommodation consists of longitudinal bench seating throughout.[2] Car 1 has a universal access toilet.[3]
