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

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

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]
