To ensure safety, we have also introduced a 60speed limit system specifically for curved sections of track.60If a train is exceeding the speed limit when passing the signal, the brakes are automatically applied6060705555456060A signal current flows through the rails, sending continuous signals to the trainIf above speed limit (1) Train in front transmits its position to Train in frontSpeed restricted until the end of the train enters the straight sectionWayside equipment radio antenna606060If above speed limit (1) Train in front transmits its position to Train in frontWayside equipment radio antennaIf a train is exceeding the speed limit when passing the signal, the brakes are automatically applied(1) Train in front transmits its position to Wayside equipment radio antennaThis system automatically controls a train’s brakes and is designed to ensure that trains do not exceed the designat-ed speed limit for each section of track. If a train gets closer to the train in front or is traveling on a curved section of track, the system automatically applies the brakes to slow the train to a safe speed, thereby maintaining a high level of safety in underground and busy sections of track. imachi Line in FY2031.Automatic Train Control (ATC) [Installed on the To-yoko, Meguro, To-kyu- Shin-yokohama, Den-en-toshi, OAutomatic Train Stop (ATS) [Installed on the Ikegami and To-kyu- Tamagawa lines]Communications-Based Train Control (CBTC) system(2) Wayside equipment transmits to train behind the limit of movement authority calculated from train in front’s positionTrain in frontTrain in frontMaintains distance from train in frontSpeed restricted until the end of the train enters the straight sectionTrain in frontTrain in frontTrain in frontTrain in front■ Maintaining distance from the train in front■ On curved sections of trackLimit of movement authorityLimit of movement authorityLimit of movement authorityDeceleration patternDeceleration pattern
