Design edit

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.

History edit

The series and its scheduled introduction into the Sotobō Line (Kazusa-Ichinomiya Station - Awa-Kamogawa Station), Uchibō Line (Kisarazu Station - Awa-Kamogawa Station), and Kashima 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 the 113 series in the late 1960s;[4][5] the previous 211 series and 209 series were transferred from other lines. On 18 December 2020, it was further announced that the series would operate certain services in the Narita Line (between Narita Station and Katori Station) and Kashima Line (between Katori Station and Sawara Station).[6][7]

On 17 June 2021, JR East announced that a new subseries will be introduced on the Sagami Line (Chigasaki Station - Hashimoto Station) in fall 2021,[8] and another subseries will be introduced into the Nikkō Line (Utsunomiya Station - Nikkō Station) and the Utsunomiya Line (Oyama Station - Kuroiso Station) in Spring 2022.[9]
