The 315 series (315系, 315-kei) is a commuter electric multiple unit (EMU) train type introduced by Central Japan Railway Company (JR Central) in the Nagoya and Shizuoka areas on 5 March 2022.

Background

JR Central has ordered 352 cars as a replacement for the 211, 213, and 311 series trains operating since the late 1980s.[3] All trains have been manufactured by Nippon Sharyo, and are the first trains to have the N-QUALIS [ja] brand.[4]

Fleet details

The fleet will ultimately consist of 42 four-car sets and 23 eight-car sets.[5] For sets based at Jinryō depot, the eight-car sets are numbered from C1 onwards while the four-car 315-3000 series sets are numbered from C101 onwards.[6][7][8] Four-car 315-3000 series sets based at Shizuoka depot are numbered from U1 onwards.[9]

Operations

Eight-car sets are used on the Chūō Main Line between Nagoya and Nakatsugawa.[10] Four-car sets based at Jinryō depot are used on the Kansai Main Line between Nagoya and Kameyama since 1 June 2023,[11] as well as on the Tōkaidō Main and Taketoyo lines in the Nagoya area since 15 March 2024.[12] Four-car sets will be used on the Shizuoka section of the Tōkaido Main Line from 1 June 2024.[13]

Interior

The design concept of the interior is "a comfortable moving space with a gentle and secure feeling."[14]

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.[14] Also featured are LCD passenger information displays and security cameras.[14][15] Priority seating areas use a different floor design and color scheme to distinguish them from general-use seating.[14]

History

The fleet was first introduced into service on 5 March 2022, with eight-car sets C2 and C6 being the first to enter service.[16]

Sets from C8 onwards are designated for fleet expansion.[17] This set also has modified cowcatchers at the end cars compared to the previous existing 8-car sets (of which there are seven).

The first two four-car sets (sets C101 and C102) began appearing in December 2022.[8] As of 21 September 2023, all 23 eight-car sets have been delivered with the appearance of set C23.[18] The thiteenth and fourteenth four-car sets (C113 and C114) were seen test-running as of 8 April 2024.[19]

Four-car sets U1 and U2, which were bound for the Shizuoka area,[9] were delivered in May 2024. These sets feature semi-automatic doors whereby passenger-operated door buttons are positioned next to the train doors.[20]
