Design

The trains have unpainted stainless steel bodies, with an exterior livery featuring red highlights.[5] Each motored car has one motored bogie.[5] The trains will be branded "Red Wing", with logos applied to the body sides and to the prominent anti-fall plates on the front ends, which inspired the name.[6]

Operations

The 227 series trains were delivered from autumn 2014 for test running and driver training before entering revenue service initially on the Sanyo Main Line between Shiraichi and Iwakuni, replacing ageing JNR-era 115 series EMUs.[1] 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.[2]

History

The first three-car set, numbered A03, was delivered to Hiroshima Depot in September 2014 from the Kawasaki Heavy Industries Rolling Stock Company factory in Kobe.[8] Sets A01 and A02 were delivered to Hiroshima Depot from Kinki Sharyo in October 2014.[9] The first two car set, numbered S01, was delivered from Kawasaki Heavy Industries in January 2015 together with three-car set A06.[10]

In March 2018, JR West announced, that starting in Spring 2019, it planned to introduce a new version of 227 series trains to Sakurai and Wakayama Lines, as well as part of Kisei Main Line. The planned 56-car fleet (28 sets of 2-car units) would displace all 105 series and 117 series trains on the two lines by Spring 2020. Once the order is complete, the trains would have smart card readers on board, expanding ICOCA acceptance to all JR West service in Nara prefecture and on Wakayama Line.[4]
