The 227 series is a DC electric multiple unit train operated by West Japan Railway Company (JR West) for use on suburban services in the Hiroshima area. The train debuted in service on 14 March 2015 on the Hiroshima City Network. The network was created on October 5, 2002, and modeled after the Urban Network in the Kyōto-Osaka-Kōbe area of Japan. Unlike the Urban Network, the Hiroshima City Network was not created in order to serve the suburbs and surrounding environs of a large city, but rather to service primarily stations within 30–40 minutes of Hiroshima Station. The 227 series trains revenue in service initially on the Sanyo Main Line between Shiraichi and Iwakuni, replacing ageing JNR-era 115 series EMUs. The trains will also displace 115 series EMUs on the Kure Line and Kabe Line, with the entire fleet of 276 vehicles (106 sets) scheduled to be delivered by the end of fiscal 2018.
