5 Fire safety measures in underground stationsCombating power outagesPreventing falls into platform gapsCrowd detection support systemsStation security camerasSecurity cameras inside the trainOnboard Safety MeasuresSafety awareness event at an after-school childcare centerCrowd detection support systemPlatform gap fillerIn March 2023, we began trialing the use of TS-Zero®—a security operations service using AI image analysis technology—at Tana and Tsukimino stations on the Den-en-toshi Line. Our aim in using it is to improve safety and customer service by leverag-ing the AI security system of Asilla, Inc. to detect falls or other problems involving passengers within our stations, so that monitoring staff at Tokyu Security’s Video Monitoring Center can check what is happen-ing and work with station staff and security guards to ensure a swift response.At all underground stations, we have secured at least two escape routes and installed emergency power supply facilities to clear smoke from platform levels in the event of a fire, in accordance with Ministry of Land, Infrastructure, Transport and Tourism standards. The power required for our trains to run is supplied to our substations by two electric power company trans-mission lines, ensuring that if one line experiences an outage, the other can maintain the supply of electricity. Additionally, a number of substations are located along each railway line, so even if one substation suffers a complete failure, the next one along the line will contin-ue to power our network. Carriages on Tokyu lines are fitted with batteries to ensure that onboard emergency lighting and announcements continue to function, even if a power outage causes the train to stop in an under-ground section of the network.At underground stations, we have installed emergency generators in case of power outages and have ensured that they are equipped with the neces-sary disaster preparedness functions, such as station announcement equipment and emergency lighting, including in the tunnels.In FY2025, we intend to install a large-scale stor-age battery system with a capacity of 10 MWh at Ichigao Substation on the Den-en-toshi Line, with the aim of both strengthening business continuity planning in the event of a disaster and contributing to a zero-carbon society.We are installing platform gap fillers on the sides of platforms to narrow gaps between trains and plat-forms, so that passengers are not at risk of falling into them if they lose their footing. We have installed fall alarms under platforms, so station or train staff are alerted if the sensor detects that a passenger has fallen off the platform. We are also implementing the Project to Prevent Falling into the Gap for the Chil-dren, aimed at ensuring that not only parents and guardians, but also children themselves are aware of the gap between the carriage and the platform when board-ing or alighting from trains.In May 2019, we began installing crowd detection sys-tems at some stations to prevent falls resulting from buildups of passengers near escalators. The system de-termines the extent of crowd buildups by analyzing foot-age from cameras inside the station. The alarm is raised by a flashing light once a crowd builds up, alerting sta-tion staff and thereby increasing passenger safety.We have installed station security cameras on plat-forms and at ticket gates, ticket machines, and ticket offices to prevent crime and enable staff to check the situation in each part of the station.In July 2020, we completed the installation of camer-as in all carriages owned by Tokyu Railways (exclud-ing the Kodomonokuni Line), to prevent terrorism, crime, and other problems on trains, and gain an accurate understanding of the situation in each car-riage.Congestion monitoring areaPredictive monitoring areaExample of security cameras installed inside the train
