Understanding the Kavach system
5TH JUNE ,2023.
The KAVACH is an indigenously developed Automatic Train Protection (ATP) system by the Research Design and Standards Organisation (RDSO) in collaboration with the Indian industry. • The trials were facilitated by the South Central Railway to achieve safety in train operations across Indian Railways. • It is a state-of-the-art electronic system with Safety Integrity Level-4 (SIL-4) standards. It is meant to provide protection by preventing trains to pass the signal at Red (which marks danger) and avoid collision. • It activates the train’s braking system automatically if the driver fails to control the train as per speed restrictions. • In addition, it prevents the collision between two locomotives equipped with functional Kavach systems. • The system also relays SoS messages during emergency situations. • An added feature is the centralised live monitoring of train movements through the Network Monitor System. ‘Kavach’ is one of the cheapest, SIL-4 certifi•ed technologies where the probability of error is 1 in 10,000 years
