The 321 series (321系?) is a commuter electric multiple unit (EMU) train type operated by West Japan Railway Company (JR West) in the Kansai Region of Japan.

Overview[edit]

The 321 series was developed from the earlier 207 series to replace the ageing 201 series and 205 series trains on the Tōkaidō Main Line. One 321 series set also replaced the 207 series (set Z16) withdrawn due to collision damage sustained in the Amagasaki rail crash of 25 April 2005.
