Achievement of 100% Installation of '3D Obstacle Detection Systems' at Railway Crossings

In July 2021, our company completed the installation of obstacle detection systems (either 3D systems using '3D sensors' or laser systems using 'laser sensors') at all railway crossings*1 on the Tokyu Line. Subsequently, as a further safety measure, we proceeded to replace the laser systems with 3D systems, which offer higher detection accuracy. On Wednesday, March 4, 2026, all replacements were completed, achieving 100% installation of 3D obstacle detection systems across all 134 crossings on the Tokyu Line.

Obstacle detection systems are designed to detect vehicles or other objects stranded within a crossing and send a signal to the driver of an approaching train to alert them of the abnormality. The 3D system can cover the entire crossing area, thereby increasing detection accuracy and further improving safety. Furthermore, while the laser system requires 10 sensors to be installed along the tracks, the 3D system requires only one, which also leads to more efficient equipment maintenance.

We will continue to strengthen our safety measures and work tirelessly to prevent accidents and build a system for early recovery in the event of an abnormality. We remain committed to providing 'safe,' 'secure,' and 'comfortable' railway services for all our customers.
