Indian Railways is upgrading the Delhi-Agra rail section with the Kavach automatic train protection system. This technology is designed to prevent train collisions and stop trains from jumping signals. The rollout aims to make travel safer and smoother for thousands of passengers using this busy corridor.
What is the current status of Kavach on the Delhi-Agra route?
Kavach 4.0 is now operational on a key part of the Delhi-Mathura route. This includes the Tughlakabad-Palwal section and New Delhi Junction Cabin, covering 21.6 route kilometers and four major station yards. The system is supported by a new optical fibre network that allows the New Delhi control room to monitor trains in real-time.

The Ministry of Railways has allocated significant funds to speed up the installation. In April 2026, ₹1,364.45 crore was approved for signaling modernization, with ₹176.77 crore specifically for the North Central Railway to cover 2,196 route kilometers across Agra, Jhansi, and Prayagraj divisions.
