NER Varanasi Division: ₹223 Crore for Kavach 4.0 on 614.75 Route km

The Ministry of Railways has approved Rs 223 crore to deploy Kavach Version 4.0 across 614.75 route kilometres of the Varanasi division of North Eastern Railway, extending automatic train protection to the remaining identified sections of the division.

The clearance was announced on Monday, 28 September. It covers the balance stretches of the Varanasi, or BSB, division that had been marked for Kavach coverage but were still waiting for the latest version of the indigenous system. Once installed, Version 4.0 will sit alongside trackside and onboard equipment already planned under the wider Indian Railways Kavach rollout.

Kavach is India's automatic train protection system. It is designed to help prevent Signal Passed at Danger incidents, apply brakes when a train is at risk of overshooting limits, and continuously monitor train movement on equipped sections. For passengers and crew on the Varanasi division, that means another layer of electronic watch on busy NER routes that carry both long-distance and regional traffic.

The Rs 223 crore sanction is a project clearance, not a claim that every kilometre is live tomorrow. Work still has to move through contracting, installation, testing and commissioning on the 614.75 route kilometres named in the approval. What Monday's decision locks is the budget envelope and the Version 4.0 specification for those remaining identified sections.

Varanasi division sits on corridors that feed Purvanchal, Bihar and eastern Uttar Pradesh passenger flows. Expanding Kavach there fits the railway ministry's stated network-wide push to put automatic train protection on more route kilometres rather than leaving protection tied only to older signalling practices. Safer and more reliable operations are the stated outcome for the division once the system is commissioned.

Version 4.0 is the current generation being pushed into new clearances. Earlier Kavach phases built the indigenous ATP idea; Version 4.0 is what the ministry is now funding for the leftover Varanasi division balance. Extending coverage to those sections closes a gap that would otherwise leave pockets of the division without the same protection suite as already-equipped stretches.

For station masters, loco pilots and control offices, Kavach changes how SPAD risk is managed on the ground. Automatic brake intervention and movement monitoring reduce reliance on reaction alone when a signal or speed limit is approached under pressure. That is the operational case behind a Rs 223 crore line item that readers will otherwise see only as a headline figure.

The ministry has not announced a commissioning date. Until installation and testing progress is notified, what stands is the Monday clearance itself: Rs 223 crore for Kavach 4.0 on 614.75 route kilometres of the Varanasi division, part of the railways' wider effort to expand the Kavach network.
