313 series

The 313 series (313系) is a DC suburban electric multiple unit (EMU) train type operated by Central Japan Railway Company (JR Central) in Japan since 1999.

The design was introduced from spring 1999 to replace older 113 and 115 series EMUs.

Although Central Liner services were discontinued in 2013, the trains continued to be used on Chūō Main Line local and rapid services until JR Central's 12 March 2022 timetable revision, and were transferred from Jinryō to Shizuoka depot from then. The sets were renumbered S1–S6 from B201–B206. From 14 March of that year, the fleet was introduced onto Tōkaidō Main Line services.
