Mumbai will be the first city to get a communications-based train control (CBTC) embedded Kavach system that will not just make the Mumbai suburban system completely safe but also ensure the headway between train services is reduced drastically and more than double the services in the next three years.

Indian Railways has been working on the Kavach safety device for some time. We have been conducting trials, while releasing various versions and now obtained the highest Safety Integrity Level (SIL)-4 with a version of Kavach-4, which will be rolled out soon,” Railway Minister Ashwini Vaishnaw told mid-day.
