Indian Railways has approved several major projects to expand the indigenous Kavach 4.0 safety system across various divisions. The goal is to prevent train accidents even if a loco pilot makes a mistake. These new approvals include significant investments in the Ahmedabad and Ambala divisions to make rail travel safer for passengers.

Where is Kavach 4.0 being installed and at what cost
The railway ministry has sanctioned funds for multiple high-traffic routes to implement the automatic train protection system. The details of the approved projects are as follows:
| Railway Division | Route Distance | Approved Cost |
|---|---|---|
| Ahmedabad Division | 598 km | ₹140 Crore |
| Ambala Division | 811 km | ₹201 Crore |
| South India (TN, KL, KA) | 548 km | ₹300+ Crore |
How does the Kavach system protect passengers
Kavach is a homegrown technology developed by RDSO with partners like Medha Servo Drives and HBL Power Systems. It acts as a shield for passengers by maintaining constant contact between the train and the signaling system. The system can automatically apply brakes to prevent a train from passing a danger signal (SPAD) or colliding with another train. It is especially useful during heavy fog or low visibility to keep the speed and distance safe.
Implementation and technical details
Railway Minister Ashwini Vaishnaw stated that India is completing this complex rollout in 6-7 years, whereas developed nations took much longer. The installation process involves laying optical fiber cables along the tracks, setting up data centers at every station, and placing telecom towers every 5 to 8 kilometers. This creates an LTE-based communication backbone that ensures the safety system works in real-time.
