Railways spend on safety

Indian Railways has approved ₹1,364.45 crore of new spending on safety systems and the digital plumbing that makes those systems work. The package, announced on April 6, stretches across four zones. It covers Kavach equipment for locomotives in Southern Railway, optical-fibre upgrades in Northern Railway and North Central Railway, and electronic interlocking at 49 stations in South Central Railway. This is not a flashy train launch. It is the slower, less visible work that lets more trains run with less room for human error (publicnow.com, moneycontrol.com). The most eye-catching piece is Kavach, India’s homegrown automatic train protection system. Railways has now sanctioned ₹208.81 crore to install on-board Kavach Version 4.0 equipment on 232 Southern Railway locomotives. Kavach is designed to intervene when a driver misses a signal or a train exceeds safe speed limits. The system can apply brakes automatically. It was adopted as Indian Railways’ national ATP system in 2020, and Version 4.0 was approved in July 2024 after earlier deployments on South Central Railway gave engineers real-world data to refine it (moneycontrol.com, pib.gov.in, pib.gov.in). That matters because Kavach is not just a box bolted into a locomotive. It depends on a communications network running beside the track. The same April 6 package includes ₹400.86 crore for three optical-fibre projects in Northern Railway and another ₹176.76 crore for a 2x48-fibre network over 2,196 route-kilometres in North Central Railway. In Northern Railway alone, the work spans more than 3,200 route-kilometres, including the Prayagraj, Jhansi, and Agra divisions. Fibre is what allows stations, locomotives, and signalling equipment to talk to each other fast enough for an automatic protection system to be useful instead of decorative (publicnow.com, psuconnect.in, pib.gov.in). The suppliers named in market disclosures help show how this build-out is being split. Kernex Microsystems has already disclosed earlier Southern Railway Kavach contracts through its joint venture with VRRC, including Chennai-division work that bundled Kavach with fibre backbone installation. Siemens India has also been tied to signalling and communications work in the current round, according to reports on the new approvals, though the cleanest public document available for the April 6 package is the Railways release itself rather than a detailed tender sheet. That is a useful distinction. The broad spending is confirmed. Some contractor-level details are still easier to trace through company filings and secondary reporting than through one central railway document (bseindia.com, psuconnect.in, railanalysis.in). The last chunk of money goes to a quieter bottleneck. South Central Railway will spend ₹578.02 crore to replace panel interlocking with electronic interlocking at 49 stations on dense routes. Interlocking is the logic system that prevents conflicting train movements through points and signals. Electronic interlocking does the same job with faster processing, easier diagnostics, and less manual handling than older panel-based systems. Railways said the point is to reduce manual intervention and improve operational safety. In practice, it also helps squeeze more trains through busy corridors without relying on old relay-era habits (publicnow.com, moneycontrol.com). This is why the card’s mention of automated berth allocation feels like a distraction. Indian Railways does use centralized software to assign berths, and its passenger systems are becoming more digital, but that is not the core of what happened this week. The real story is that Railways is spending heavily on the invisible layers beneath train operations: onboard protection, fibre links, and station logic. By mid-March, the government said Kavach 4.0 had already been commissioned on 1,452 route-kilometres of the Delhi-Mumbai and Delhi-Howrah corridors, with 8,570 km of optical fibre laid and 767 station data centers set up. The new approvals extend that same architecture, one locomotive, one cable run, and one interlocking panel at a time (pib.gov.in, publicnow.com).
