Kavach funding pushed

Indian Railways has approved ₹1,364.45 crore in new works to expand Kavach, its in-house train protection system, and to upgrade the signalling and communications gear that Kavach needs to work at scale. The package is spread across four zones. It includes ₹208.81 crore to fit Kavach 4.0 equipment on 232 locomotives in Southern Railway, ₹400.86 crore for new fibre-optic networks in Northern Railway, ₹176.76 crore for more fibre in North Central Railway, and ₹578.02 crore to replace older panel interlocking with electronic interlocking at 49 stations in South Central Railway (ndtvprofit.com, infra.economictimes.indiatimes.com). That mix matters because Kavach is not a gadget you bolt onto a train and forget. It is an automatic train protection system. It watches signals, checks speed, knows where trains are, and applies the brakes if a driver misses a danger signal or if a collision risk appears ahead. Indian Railways adopted it as the national ATP system in July 2020, after earlier field trials began in 2016 and version 3.2 was deployed on South Central Railway (pib.gov.in, ndtvprofit.com). The new money is really an admission that the hard part was never the software. It was the plumbing. Kavach needs radios, towers, RFID tags, station equipment, locomotive equipment, and a robust optical-fibre backbone along the track. That is why more than ₹577 crore of this approval goes not to locomotives but to fibre cable in the north, and another ₹578 crore goes to electronic interlocking in the south. Without those layers, the system cannot reliably feed trains the signal and route data that makes automatic protection possible (pib.gov.in, ndtvprofit.com). This is also why the headline number can sound bigger than the immediate effect. Only one slice of the package directly equips trains with Kavach right now: 232 locomotives in Southern Railway. The rest builds out the network around them. Indian Railways is folding that work into a much larger ₹27,693 crore umbrella programme for Kavach deployment with an LTE communication backbone, with ₹2,950 crore already earmarked for Southern Railway under that broader scheme (ndtvprofit.com, infra.economictimes.indiatimes.com). The push comes after a long stretch in which Kavach was politically central but physically limited. As of February 2025, Indian Railways said it had laid 5,743 km of optical fibre for Kavach, installed 540 telecom towers, equipped 664 stations, fitted 795 locomotives, and installed trackside equipment over 3,727 route-km. Yet the actual commissioned footprint of Kavach 4.0 was still modest. On January 30, 2026, the government said the newest version had been commissioned over 1,306.3 route-km across five zones, even after a single-day record addition of 472.3 route-km (pib.gov.in, pib.gov.in). That gap helps explain the urgency behind this week’s approval. Kavach 4.0 itself is new. The Research Designs and Standards Organisation approved it on July 16, 2024, after Indian Railways used lessons from version 3.2 to improve location accuracy, signal visibility in large yards, station-to-station communication over fibre, and direct links to electronic interlocking. In other words, the latest version was built for exactly the kind of dense, messy, mixed-traffic railway that India runs every day (pib.gov.in, pib.gov.in). And density is the real point. A safer railway is not just one with fewer crashes. It is one that can run more trains closer together without depending on perfect human attention every minute. Electronic interlocking speeds route setting and reduces manual failure points. Fibre networks make signalling and train-to-ground communication more dependable. Kavach sits on top of that stack and turns it into enforced discipline. The biggest single allocation in this package, ₹578.02 crore for 49 stations in the Guntakal and Nanded divisions, goes exactly to that quieter layer of control logic that passengers never see from the window (ndtvprofit.com, infra.economictimes.indiatimes.com).
