Indian Railways has approved a project worth ₹140 crore to install the indigenous ‘Kavach 4.0’ system in the Ahmedabad Division of Western Railway. This safety upgrade will cover 598 route kilometers and 48 block sections to prevent train collisions. The move is part of a larger strategy to modernize train operations and enhance safety standards across the national network.
How does Kavach 4.0 work to prevent accidents?
Kavach is an Automatic Train Protection (ATP) system developed by RDSO. It is designed to prevent ‘Signal Passing at Danger’ (SPAD) by automatically applying brakes if a train crosses a red signal. The system works on SIL-4 standards, meaning the chance of failure is only one in a million. It can control train speed in critical situations and is effective for trains running up to 160 kmph.
What are the key features of the new system?
The 4.0 version of Kavach brings several advanced technical upgrades for better safety and communication. These include:
- AI-based decision making for real-time analysis of speed and track conditions.
- Ultra-fast response time and LTE-based communication backbone.
- Digital dashboards for loco pilots and location-specific alerts.
- Auto-whistling features to warn people on the tracks.
What is the scale of Kavach expansion in India?
The Indian Railways is investing heavily in this technology across multiple zones. The recent approvals include several high-traffic routes:
| Region/Division | Route Distance | Project Cost |
|---|---|---|
| Ahmedabad Division | 598 km | ₹140 crore |
| Ambala Division | 811 km | ₹201 crore |
| South India (TN, KL, KA) | 548 km | ₹300+ crore |
DRM Ahmedabad, Ved Prakash, stated that after this new approval, the entire 1300 km route network of the Ahmedabad Division will be 100% equipped with Kavach 4.0.
