The E131 series (E131系) is a DC electric multiple unit (EMU) train type operated by the East Japan Railway Company (JR East). It began operations in the Chiba area on 13 March 2021, on the Sagami Line on 18 November 2021, and on the Nikkō Line and Utsunomiya Line on 12 March 2022. The trains are equipped for driver-only operation (wanman (ワンマン, "one man")).

Design

The E131 series trains have stainless steel bodies.[1] They have LCD passenger information displays above the doors,[1] as well as wheelchair- and stroller-accessible "free spaces" on all cars. As they are equipped for driver-only operation, body-mounted cameras are utilized to monitor passengers boarding and alighting the train; these cameras are 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

The series and its scheduled introduction into 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;[4][5] the 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 Utsunomiya Line (Oyama Station - Kuroiso Station) in Spring 2022.[9]
