Automatic train protection system on Delhi-Mumbai route: Kavach 4.0 commissioned on Vadodara-Nagda section

With this milestone, out of the total 693 RKm identified under Western Railway on the Mumbai-New Delhi main corridor as part of Mission Raftaar, Kavach has now been installed on 559.5 RKm.

Indian Railways Kavach system deployment progress

During the financial year 2025-26, Western Railway has commissioned Kavach over a total of 659.5 RKm. Earlier, in January 2026, Vadodara Division had operationalized the Kavach system on the Vadodara-Virar section and now the system has been extended up to Nagda via Godhra.

In a statement, the zonal railway said: “The execution of this complex project on the Vadodara–Nagda section involved meticulous planning for each station and every absolute/automatic signalling section. Over 6,000 RFID tags were programmed and installed along the tracks.

Continuous radio communication was established among 26 stations, 13 block sections, and locomotives. A total of 39 radio towers along with associated equipment were installed.”

It further said that around 600 km of OFC cable was laid in both Up and Down directions across the route.

Kavach 4.0: Here’s how the rail safety system works

The Kavach is an makes rail operation safer by applying brakes in trains in critical situations. The system automatically protects against Signal Passing at Danger (SPAD), Head-on and rear-ends collision risks. Moreover, Overspeeding is continuously monitored and controlled and Safety is ensured even in low visibility and adverse weather conditions.

It complies with SIL-4 safety standards, the highest level of safety integrity globally. Being an indigenously designed and cost-effective system, it reduces dependence on imported technologies and promotes Indian signaling industry.
