The 323 series (323系, 323-kei) is a DC electric multiple unit (EMU) train type operated by West Japan Railway Company (JR West) on the Osaka Loop Line in Osaka, Japan, since December 2016. The trains are replacing ageing 103 series and 201 series trains.[1]

The eight-car trains have stainless steel bodies, and the exterior livery features orange highlights.[1] Each car has three pairs of sliding doors per side, unlike the four pairs per side on 103 and 201 series trains.[1]

Formation

The trains are formed of eight cars formed as follows, with all cars motored (only one motored bogie per car).[2]

Car 4 is designated as a women-only car.[3]

Interior

Passenger accommodation feature longitudinal bench seating throughout, with priority seating at one end of each car, and a wheelchair/stroller space at the opposite end.[4] The passenger saloons use LED lighting, with the lighting in car 4 (women-only car) adjusted to have a more orange "tungsten lighting" tinge to distinguish it from other cars.[3] Passenger information announcements are provided in two languages, and information screens are in four languages (Japanese, English, Chinese, and Korean), with pairs of screens over each door, and pairs at either end of the cars.[4] WiFi service is also provided.[4]

Entry into service

A total of 21 eight-car sets (168 vehicles) are scheduled to be introduced between fiscal 2016 and 2018, entirely replacing the fleet of 23 103 and 201 series trains.[4] The first trains will enter revenue service on 24 December 2016.[5]
