A total of 97 vehicles were built. These consist of 46 vehicles for Kinosaki, Kounotori, Maizuru, and Hashidate services, formed as seven 4-car sets and six 3-car sets, which will partially replace the ageing fleet of 86 183 series vehicles currently used on these services.[7] A further batch of 51 vehicles for Kuroshio services consists of six 6-car sets and five 3-car sets, replacing older 381 series EMUs. These entered service from the start of the revised timetable on 17 March 2012.[5][6]
Design
The trains are based on the earlier 683 series Thunderbird design with increased front-end crash protection and the inclusion of crushable zones for the first time on JR-West limited express rolling stock.[7] Livery is similar to that used on 683 series Thunderbird sets, with a maroon stripe below the dark grey window band for the Kinosaki and Kōnotori trains,[8] and "ocean green" for the Kuroshio trains.[5][6]
