India railways approves ₹381 crore Kavach safety upgrades
Indian Railways has approved two projects worth ₹381 crore to expand the indigenous Kavach automatic train protection system and strengthen locomotive infrastructure. The investment covers Kavach Version 4.0 on 680 route kilometres and the first Standard KAVACH commissioning in Solapur Division, advancing a nationwide push to reduce collision and SPAD risks on India's railway network.
Key Takeaways
- Indian Railways cleared ₹381 crore for Kavach rollout and locomotive infrastructure upgrades.
- A ₹206 crore project will deploy Kavach Version 4.0 across 680 route km on Northern Railway's Rewari-Delhi and Shakurbasti-Bathinda sections.
- Central Railway commissioned Standard KAVACH on the 149.476-km Solapur-Wadi section—the first deployment in Solapur Division.
- Kavach is India's indigenous ATP system designed to prevent SPAD incidents and train collisions through automatic braking.
- A separate ₹175 crore project will enhance electric locomotive homing facilities at Raipur under South East Central Railway.
What is Kavach and why does it matter for railway safety?
Kavach is India's indigenously developed Automatic Train Protection (ATP) system, built to strengthen railway safety by preventing Signal Passed at Danger (SPAD) incidents and train collisions. The Ministry of Railways says it continuously monitors train movements and automatically applies brakes whenever necessary.
Kavach Version 4.0 includes improved location accuracy, stronger communication systems, and enhanced integration with railway signalling infrastructure. These upgrades support large-scale deployment across high-density routes where passenger and freight traffic continue to grow.
Where will the new Kavach systems be deployed?
The largest share of the ₹381 crore approval is a ₹206 crore project to deploy Kavach Version 4.0 across 680 route kilometres of Northern Railway. The system will cover the Rewari-Delhi and Shakurbasti-Bathinda sections, including feeder branch lines, under the Delhi Division.
According to the Ministry of Railways, this project forms part of an ongoing nationwide Kavach rollout across high-density and strategically important routes. Kavach Version 4.0 has already been commissioned across major sections, including parts of the Delhi-Mumbai and Delhi-Howrah corridors, with the system expanded across more than 1,300 route kilometres through multiple commissioning milestones.
Separately, Central Railway's Solapur Division commissioned Standard KAVACH on the 149.476-km Solapur-Wadi section—marking the first such deployment in the division. Details on this rollout were reported by The Hindu.
How does Standard KAVACH work on the Solapur-Wadi route?
The Standard KAVACH system is a non-signalling-based variant that operates through continuous communication between Kavach-equipped locomotives and railway infrastructure. It uses Radio Frequency Identification (RFID)-based track identification to ensure accurate train positioning.
As part of the Solapur-Wadi project, 1,234 RFID tags were installed and programmed across the section. Before commissioning, the system underwent comprehensive validation and field trials under Research Designs and Standards Organisation (RDSO) standards, including tests of head-on collision prevention, rear-end collision prevention, and SOS alert generation.
The system is designed to prevent head-on and rear-end collisions while enabling automatic or manual SOS alerts if a train makes an unusual stop within a block section. Commissioning was carried out by the Signal and Telecommunication Department, Project Unit, Solapur Division.
What else is included in the ₹381 crore approval?
Beyond Kavach deployment, Indian Railways approved a ₹175 crore project to enhance electric locomotive homing facilities at Raipur under South East Central Railway. This infrastructure upgrade is intended to support the expanding electric railway ecosystem as traffic volumes rise across the network.
Recent government approvals have also covered optical fibre communication upgrades and signalling modernisation alongside Kavach deployment. Together, these investments reflect a broader transport transformation focused on technology-driven safety and reliability—a theme covered regularly in our Future Tech & AI Wonders coverage.
The Railway Board expects Kavach Version 4.0 on Northern Railway routes to strengthen safety, improve operational efficiency, enhance reliability, and support faster movement of both passenger and freight services, even during adverse weather such as dense fog.
