“The contract is to design, supply, installation, testing and commissioning of Anti Drag Passenger Door Safety System in all the saloon doors of CMRL Phase-1 trains, as part of CMRL’s ongoing commitment to enhance passenger safety and service excellence by introducing an upgraded door safety mechanism across all the trains operating on the Blue and Green lines of Phase-1,” the Chennai Metro Rail said in a statement.

What is Anti-Drag Passenger Door feature on Metro trains?

Currently, CMRL’s metro trains are fitted with automatic sliding doors equipped with an obstacle detection system that identifies objects obstructing the doors during closure at stations. However, the new Anti-Drag Passenger Door Safety System will further enhance passenger safety by detecting thinner objects such as sarees, bag straps, or belts that may get trapped between doors during boarding or deboarding.

This advanced system can detect any “pull” or “drag” force. If such an item is dragged as the train begins to move, the system will automatically trigger the emergency brake and provides an instant alert to the train operator through the driver’s console for immediate action.

“While Chennai Metro Rail has reported zero accidents due to door entrapment, this upgrade is a proactive and enhanced safety measure aimed at strengthening passenger protection, particularly for women commuters, and ensuring world-class safety standards across the system. This Anti-Drag Feature will also be incorporated as a standard provision in all trains being procured under Phase 2 of the Chennai Metro Rail Project,” it said in a statement.
