# 323 series

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 replaced the ageing 103 series and 201 series trains.

## Design

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

## 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. 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. On car 8, the seats closest to the doors are removed to improve passenger circulation. 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. WiFi service is also provided.
