Indian Railways has sanctioned a ₹206 crore investment to deploy Kavach Version 4.0 — the country's indigenous Automatic Train Protection (ATP) system — across 680 route kilometres of the Rewari-Delhi and Shakurbasti-Bathinda sections, including feeder branch lines, under the Northern Railway's Delhi Division. The approval, confirmed through an official statement on Friday, 10 July, marks a significant expansion of the nationwide Kavach rollout on high-density corridors.

What Kavach Version 4.0 Does

Kavach is designed to prevent two of the most critical failure modes in rail operations: Signal Passed at Danger (SPAD) incidents and train collisions. The system continuously monitors train movements in real time, automatically applies brakes when a hazard is detected, and allows trains to operate safely at maximum permissible speeds. Notably, it also ensures reliable operations during dense fog — a persistent challenge on Northern Railway routes through the winter months.

Version 4.0 represents an enhanced iteration of the earlier system, with improvements in processing reliability and inter-system communication. Its deployment on the Rewari-Delhi and Shakurbasti-Bathinda corridors — both strategically important for passenger and freight movement — is expected to strengthen operational safety margins considerably.

Part of a Wider National Push

The sanctioned project is embedded within Indian Railways' broader, ongoing programme to extend Kavach coverage across high-density and strategically critical routes nationwide. The Delhi Division corridors selected for this phase carry significant mixed traffic loads, making the safety upgrade operationally consequential beyond just the immediate sections.

According to the official statement, the deployment will also improve operational efficiency and support faster, technology-driven movement of both passenger and freight services on these routes.

₹175 Crore for Locomotive Homing at Raipur

In a separate but related approval, Indian Railways has also cleared a ₹175 crore project to create additional homing facilities for 250 three-phase electric locomotives at the High Horse Power (HHP) Diesel Shed in Raipur, under the South East Central Railway (SECR).

Homing refers to the formal assignment of a locomotive to a designated maintenance shed — its primary base for scheduled upkeep, safety inspections, and repairs. The Raipur depot expansion has been sanctioned to keep pace with the rapid growth of the electric locomotive fleet and rising freight and passenger volumes across the network.

The additional capacity will allow Indian Railways to better utilise existing infrastructure while creating headroom for future technological expansion at the Raipur depot, according to the statement.

What This Means for Rail Safety

Together, the two approvals — totalling ₹381 crore — reflect a continued institutional push to modernise both safety systems and maintenance infrastructure simultaneously. The Kavach rollout, in particular, has gathered pace following high-profile train accidents in recent years that renewed public and parliamentary scrutiny of railway safety standards.

With the 680 km Northern Railway deployment now approved, the focus will shift to execution timelines and whether the on-ground rollout meets the pace that the scale of India's rail network demands.
