New Delhi, September 28, 2026: Indian Railways has commissioned Kavach Version 4.0 over 108 route kilometres of the Malkajgiri–Kamareddi section in Telangana, marking the first deployment of the upgraded system on South Central Railway.
The work covers the Hyderabad Division and upgrades the section from Kavach Version 3.2 to Version 4.0. The Ministry of Railways said the new version incorporates operating experience from Version 3.2 already deployed across 1,465 route kilometres of South Central Railway.
Kavach is Indian Railways’ indigenous Automatic Train Protection (ATP) system. According to the Railway Ministry, Version 4.0 includes enhanced train-location accuracy, improved signal information in larger yards, station-to-station optical-fibre communication and direct interfaces with electronic interlocking systems.
The system is designed to help prevent Signal Passing at Danger and can automatically apply brakes when required. Its deployment therefore combines onboard equipment with trackside, signalling, telecom and station infrastructure.
The Telangana commissioning follows a separate Railway Ministry approval of ₹252 crore for Kavach 4.0 across 607.7 route kilometres of the Lucknow Division of North Eastern Railway.
The two developments are at different stages: the Malkajgiri–Kamareddi upgrade has been commissioned, while the Lucknow Division programme has been approved for implementation.
Equipment Brief analysis: Train-protection technology is also an infrastructure programme. Deployment involves optical fibre, signalling interfaces, RFID-based track assets, station systems, telecom equipment and locomotive integration. That creates work for signalling contractors, telecom specialists, systems integrators and railway engineering companies alongside technology suppliers.
As railway investment combines civil capacity expansion with digital safety systems, contractors increasingly operate in a market where infrastructure delivery is more technology-intensive.
The 108-route-km commissioning provides an operational reference for Kavach 4.0 on South Central Railway. The next industry question is how quickly approved route kilometres elsewhere translate into tenders, installation work, system integration and commissioned coverage.
Equipment Brief also tracks the civil side of railway expansion in its guide to heavy equipment for metro and rail projects and recent Dedicated Freight Corridor project updates.
