JR East E235 Series / JR東日本E235系
The E235 Series (E235系) is an EMU operated by JR East in the Greater Tokyo Area.
First introduced to the Yamanote Line in 2015, the E235 series was developed as a successor to the E231 and E233 series. 50 11-car sets (550 cars) were produced for the Yamanote Line, fully replacing the E231 series. A modified suburban variant (E235-1000 series) entered service on the Yokosuka and Sōbu Lines in late 2020, intended to replace the aging E217 series. This variant is composed of 11-car sets (of which there are 2 reserved green cars) and 4-car additional sets, which can operate independently or coupled together as a 15 car formation. 348 -1000 series cars have been produced to date, with hundreds more on order.
