TheE131 series (E131系) is a DCelectric multiple unit (EMU) train type operated by theEast Japan Railway Company (JR East). It began operations in the Chiba area on 13 March 2021, on theSagami Line on 18 November 2021, and on theNikkō Line and theUtsunomiya Line on 12 March 2022. The trains are equipped fordriver-only operation (wanman (ワンマン; "one man")).
The E131 series trains have stainless steel bodies.[1] They have LCD passenger information displays above the doors,[1] as well as wheelchair-accessible and stroller-accessible "free spaces" on all cars. As they are equipped for "wanman" driver-only operation, body-mounted cameras are utilized to monitor passengers boarding and alighting the train; these cameras are then fed to displays located in the driver's cab.[1][2] They also feature semi-automatic doors, allowing passengers to operate the doors during driver-only operation.[1][2]
Internally, the trains are equipped with security cameras and emergency call switches.[1]
Some trains in each subseries are numbered -X80, as they have a slightly different equipment configuration due to the presence of track monitoring equipment.
The series and its scheduled introduction into theSotobō Line (Kazusa-Ichinomiya Station -Awa-Kamogawa Station),Uchibō Line (Kisarazu Station -Awa-Kamogawa Station), andKashima Line (Sawara Station -Kashimajingū Station) was announced on 5 May 2020.[3] It was the first all-new series introduced in the region in 51 years since the113 series in the late 1960s;[4][5] the previous211 series and209 series were transferred from other lines. On 18 December 2020, it was further announced that the series would operate certain services in theNarita Line (betweenNarita Station andKatori Station) andKashima Line (betweenKatori Station andSawara Station).[6][7]
On 17 June 2021, JR East announced that a new subseries will be introduced on theSagami Line (Chigasaki Station -Hashimoto Station) in fall 2021,[8] and another subseries will be introduced into theNikkō Line (Utsunomiya Station -Nikkō Station) and theUtsunomiya Line (Oyama Station -Kuroiso Station) in Spring 2022.[9]
On 24 December 2024, JR East announced another subseries that will run on theSenseki Line in the Sendai area.[10]
