<h1>Railway Board Extends Deadline for Kavach Train Protection System on Key Routes to December 2025</h1> The Railway Board has extended the deadline for installing the Kavach Automatic Train Protection System on the Delhi-Mumbai and Delhi-Kolkata routes to December 2025. Initially set for March 2025, the extension allows for the completion of track-side equipment on the 3,000 km route. Kavach, approved in 2020 and upgraded to Version 4.0 in July 2024, involves complex technology including RFID tags, telecom towers, and optical fiber cables. The installation aims to enhance train safety by automatically applying brakes and is part of a larger plan to cover the entire Indian rail network within six years.
