In a bid to enhance passenger safety and streamline the operations of long-distance trains, the Railway Ministry is implementing Kavach technology across the Western Railway zone. This advanced Automatic Train Protection (ATP) system will be installed on 789 kilometers of Western Railway lines, including the 56-kilometer stretch from Churchgate to Virar in Mumbai, as per Indian Express.
What is Kavach Technology?
Kavach is a sophisticated ATP system designed to prevent train collisions and improve operational safety. It utilizes radio frequency identification (RFID) systems installed at stations, trains, and tracks. In the event that a loco pilot overlooks a red signal, Kavach automatically engages the train’s brakes. The system also detects oncoming trains on the same tracks, taking necessary steps to prevent collisions while alerting the loco pilot.
Key Details:
- Estimated Cost: Rs 70 lakh per unit
- Expected Completion: By 2025
The technology allows trains to operate at safe speeds, assists loco pilots in avoiding Signal Passing at Danger (SPAD), and provides continuous speed monitoring. Kavach also displays signal information in the loco pilot’s cabin, offering protection against possible collisions.
Project Progress
Four contracts for the installation of Kavach across 789 kilometers of tracks and 90 locomotives were awarded between October 2022 and December 2023. The project is expected to be completed within 24 months. So far, loco trials have been successfully conducted over 405 kilometers, with a goal of covering 735 kilometers by FY 2024-25.
For the Mumbai Central to Virar section (54 kilometers), a contract was awarded in December 2023, and survey work is currently in progress. However, this phase of the project will only apply to long-distance trains and not to the suburban train network.
Official Statement
Vineet Abhishek, Chief Public Relations Officer for Western Railway, emphasized the importance of Kavach, stating, “The Kavach system will significantly enhance safety and operational efficiency. While it is still in the trial stage, we anticipate its implementation soon. Kavach will play a crucial role in reducing SPAD incidents and preventing potential collisions, thereby increasing overall safety.”
