Signal Passing at Danger

Modernising railway safety through Kavach and AI

Kavach is India’s indigenously developed Automatic Train Protection system designed to enhance railway safety by preventing Signal Passing at Danger, over-speeding, and train collisions through real-time monitoring and automatic braking. With implementation on over 2,200 route kilometres and the rollout of Kavach 4.0, Indian Railways is strengthening safety on high-density corridors. Complemented by AI-based surveillance, predictive maintenance, and advanced telecom infrastructure, these technology-led measures are reducing human error, enabling higher-speed operations, and building a safer, more reliable, and future-ready railway network.
