The Anti-Drag safety feature is now integrated into Phase-1 Chennai Metro trains’ automatic sliding doors to augment protection beyond the existing obstacle detection system.

CMRL marked a significant safety milestone by flagging off the first metro train equipped with the Anti-Drag feature for Phase-1 commuters.

India’s first anti-drag safety implementation in Phase-1 Chennai Metro trains aims to prevent passengers from being dragged if garments or objects get trapped in doorways.

The development aligns with EN 14752:2025 international standards and represents a global-first design from CMRL, Faiveley, and Alstom.

CMRL emphasizes passenger safety, operational reliability, and international collaboration to protect women and the elderly in crowded conditions.

The launch ceremony was led by CMRL officials and included senior executives from Faiveley Transport Rail Technologies India and Alstom Transport India Limited.

Public-private collaboration was highlighted as part of the ceremony, underscoring industry partnership in delivering the safety upgrade.

The upgraded train was officially flagged off for passenger service by Manoj Goyal, with attendance from senior CMRL leadership and technology partners.

The overarching goal is to reduce door-entrapment incidents, improve reliability during peak hours, and promote a passenger-centric approach to urban mobility.

CMRL plans to retrofit the safety mechanism across the remaining 51 Phase-1 trains after the initial successful launch.

This is a pioneering implementation in the Indian metro sector and among the early global deployments under EN 14752:2025 railway door safety standards.

The system operates in real time with automatic braking and door reversal, using sensors to monitor forces in all directions for high reliability.
