Design
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.
