Safety-related works in railways- The “KAVACH” system
Context
The Economic Survey 2023-24 indicated limited progress on safety-related works such as the deployment of the automatic train protection system Kavach and overhaul of signaling systems at all stations.
About the Kavach system:
- Kavach, an automatic train protection (ATP) system, developed by the Research Design and Standards Organisation (RDSO) in collaboration with the Indian industry.
- It is a state-of-the-art electronic system with Safety Integrity Level-4 (SIL-4) standards.
- It is meant to protect 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 emergencies.
- SoS means, a call or request for help or rescue.
Current deployment:
- It has been deployed on 1,465 route km in the South-Central Railway, the Survey states.
- This is just 2.14% of the total railway network of 68,426 route km and 7,349 railway stations.
