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]
