How does automatic train protection system work as railways approves ₹341 cr 'Kavach'?

Indian Railways approved a ₹341 crore project to deploy Kavach, an indigenously developed Automatic Train Protection system, which makes rail operations safer by automatically applying brakes in critical situations. It automatically protects against Signal Passing at Danger, head-on, and rear-end collision risks. Overspeeding is monitored and controlled, ensuring safety even in low visibility.
