Indian Railways approves an expansion of its train protection system, Kavach, covering operations in the Ambala and Ahmedabad divisions, according to multiple reports. The plan involves rolling out Kavach under the next phase of deployment, commonly referred to in coverage as Kavach 4.0 for the Ahmedabad division. One report states the expansion across the Ambala and Ahmedabad divisions totals about ₹341 crore. Another outlet reports a separate approval for the Ahmedabad division, citing a budget of roughly ₹140 crore for the Kavach project there. While the articles differ on the quoted total project value and whether they describe the programme as covering both divisions together or Ahmedabad specifically, they align on the core point that Railways has cleared funding for Kavach deployment in these regions. The approvals indicate continued scaling of the indigenous train collision avoidance and protection system aimed at improving railway safety. The coverage does not describe a start date or completion timeline.
