Implementation of one-person operation of 4-car 315 series trains and installationof a safety confirmation support device that uses image recognition technology
We work to restrengthen our management capabilities by using the latest technology. As
part of our business reforms to create an efficient business execution system, we have beenworking toward implementing one-person operation of four-car 315 series trains using
cameras installed on the side of the cars (hereinafter referred to as “side-mounted cameras”).
In this situation, in order to improve safety, we have considered the use of image recognition
technology that detects people approaching trains using images from the side-mounted
cameras. Now that we are confident that this technology can be put to use, we are pleased toannounce that we have decided to equip four-car 315 series trains with a safety confirmation
support device that uses image recognition technology. We would also like to inform you about
future plans for one-person operation of four-car 315 series trains.
1. Verification results of image recognition technology
 Starting in June 2023, four-car 315 series trains equipped with sidemounted cameras were put into service. As a result of having AI learn
data taken at various times and in various weather conditions, verifying
image recognition technology, and improving its detection accuracy, it
was confirmed that it is possible to detect people approaching a train.

detection
 On trains with a driver and a conductor on board, the conductor
operates the doors. Meanwhile, on one-person operated trains equipped with sidemounted cameras, the driver checks the images of the platform from the cameras on amonitor in the driver’s cab and operates the doors.
 A safety confirmation support device automatically detects people approaching the train
after the doors close, using images from two side-mounted cameras installed on the front
and rear sides of each car, and notifies the driver with an alarm or other means so thatthe driver can stop the train. In this way, this device can better support the driver inchecking safety, leading to improvement in the safety of one-person operation using sidemounted cameras.
3. Implementation plan for one-person operation of 4-car 315 series trains (Attachment 2)
 This one-person operation will be implemented on the Kansai Line (between Nagoya
Station and Kameyama Station) and the Taketoyo Line during FY2025.
 From FY2026 onwards, this one-person operation will be gradually implemented on theTokaido Line (between Mishima Station and Numazu Station, between Hamamatsu
Station and Toyohashi Station, between Ogaki Station and Maibara Station), the Gotemba
Line, and other lines.
4. Other The images captured by the side-mounted cameras are intended to detect approachingpassengers and to allow the driver to check platform safety, but are not intended toidentify specific individuals.

one-person operation installed on the platform Check platform safety with a convex mirror for one-person operation when thetrain departs<Future (4-car 315 series train)> Check platform safety with images from the side-mounted
cameras, which are projected onto a monitor in the driver’s cab

 If a person approaches the train after the doors close, this isautomatically detected using AI-based image recognition
technology.
 The driver is notified of the detection by an alarm or othermeans.
