Why is this in the news?

The Press Information Bureau (PIB) released a statement on 28 September 2026, announcing the sanctioning of ₹223 crore by the Ministry of Railways for the implementation of KAVACH 4.0 on 614.75 kilometres of the Varanasi Division under the North Eastern Railway. This initiative marks a significant step in strengthening railway safety infrastructure through indigenously developed technology, aimed at preventing Signal Passing at Danger (SPAD) incidents and enhancing operational reliability.

Background

• KAVACH is an indigenous Automatic Train Protection (ATP) system developed by the Indian Railways in collaboration with Research Designs and Standards Organisation (RDSO) and private sector partners.
• The system is designed to prevent collisions by automatically applying brakes when a train approaches a danger signal or exceeds permissible speed limits.
• The Varanasi Division, part of the North Eastern Railway, is a critical route connecting major urban centres in Uttar Pradesh and Bihar, necessitating robust safety measures.
• The project aligns with the Indian Railways’ broader objective of achieving zero accidents and improving passenger safety through technological interventions.
• KAVACH has been tested on various routes, including the Lingampalli-Wadi and Secunderabad-Manmad sections, demonstrating its efficacy in reducing SPAD incidents.

What is KAVACH 4.0?

• KAVACH 4.0 is an indigenously developed Automatic Train Protection System (ATPS) designed to enhance railway safety by preventing collisions and overspeeding.
• Key features include automatic braking when a train approaches a danger signal or exceeds the permissible speed limit, thereby mitigating the risk of Signal Passing at Danger (SPAD).
• The technology is part of the Indian Railways’ broader strategy to reduce accidents and improve passenger safety through indigenous innovation.
