South Central Railway Exceeds Targets for Kavach 4.0 Trials and ABS Rollout

The push signals quicker adoption of homegrown train control to raise safety and capacity.

Overview

South Central Railway reported completing Kavach 4.0 field trials over 487 route kilometres in 2025–26, beating the Railway Board's 402 km goal.
Kavach trials used equipment mounted on locomotives that can brake a train that passes a danger signal and keep speed within limits.
The zone also commissioned Automatic Block Signalling on 479 route kilometres, exceeding the 357 km target set for the year.
ABS went live on the Kazipet–Balharshah, Vijayawada–Duvvada, and Wadi–Renigunta corridors to let multiple trains follow safely without rear-end risk.
General Manager Sanjay Kumar Srivastava said Kavach and ABS rollout now ranks as a top priority to lift safety and throughput on busy routes.
