Indian Railways approves Kavach 4.0 on 607 km UP section for ₹252 crore
Synopsis
Key Takeaways
Indian Railways on Saturday, 19 September 2026, approved the deployment of Kavach Version 4.0 across 607.7 route kilometres of the Lucknow Division of Northeastern Railway at a total outlay of ₹252 crore. The move extends automatic train protection coverage to the remaining balance sections of the division, reinforcing safety infrastructure on one of the country's busiest rail corridors.
What Kavach 4.0 Does
Kavach is an indigenously developed Automatic Train Protection (ATP) system engineered to prevent collisions and reduce human error. It guards against Signal Passing at Danger (SPAD) — one of the leading causes of rail accidents — by automatically applying brakes when a train approaches a red signal without slowing down. The system also continuously monitors train operations to support safer movement across the network.
Version 4.0 represents the latest iteration of the technology, with enhanced reliability and integration capabilities compared to earlier deployments. Indian Railways has been progressively rolling out Kavach across its vast network as the centrepiece of its modernisation-through-indigenous-technology strategy.
Electronic Interlocking Approved for Solapur Division
In a parallel decision, Indian Railways also approved the provision of Electronic Interlocking (EI) at seven stations of the Solapur Division of Central Railway, at a cost of ₹209 crore. The stations covered are Mohol, Mundhewadi, Bale, Solapur, Hotgi Junction-Hotgi A Cabin, Shahabad, and Wadi Junction — all on the High Density Network (HDN) 7 route.
Electronic Interlocking replaces older relay-based systems with a computer-controlled signalling architecture that offers faster fault detection, easier maintenance, and more efficient train operations. Critically, EI is a prerequisite for layering Kavach, Automatic Block Signalling (ABS), and Centralised Traffic Control (CTC) — all of which have already been sanctioned for this route.
Why These Approvals Matter
Both decisions are part of Indian Railways' broader, multi-year programme to modernise signalling infrastructure across high-density corridors. The Lucknow Division handles significant passenger and freight traffic on the Northeastern Railway network, making the Kavach rollout there operationally consequential. The combined outlay for both projects stands at ₹461 crore.
Notably, momentum behind Kavach deployment accelerated following high-profile rail accidents that prompted public and parliamentary scrutiny of train protection systems. The government has since fast-tracked approvals, with Saturday's sanctions reflecting that continuing push.
Outlook
With these approvals, Indian Railways inches closer to its stated objective of blanketing the entire network with Kavach coverage. Implementation timelines and tendering processes for both projects are expected to be detailed in subsequent official communications.
