Interior

The design concept of the interior is "a comfortable moving space with a gentle and secure feeling."[7]

Passenger accommodation consists of longitudinal seating throughout; each seat has a per-occupant width of 46 centimetres (18 in), a 1 cm (0.39 in) increase over those of the 211 series. Wheelchair spaces are provided in every car.[7] Also featured are LCD passenger information displays and security cameras.[7][8] Priority seating areas use a different floor design and color scheme to distinguish them from general-use seating.[7]

History

JR Central has ordered 352 cars as a replacement for the 211, 213, and 311 series trains operating since the late 1980s.[9] The fleet was first introduced into service on 5 March 2022, with eight-car sets C2 and C6 being the first to enter service.[10]

Sets from C8 onwards are designated for fleet expansion.[11] This set also has modified cowcatchers at the end cars compared to the previous existing 8-car sets (of which there are seven).

The four-car sets began appearing in December 2022, of which two have been built since then.[6] Three eight-car sets have yet to be delivered as of 8 August 2023.[12]
