Recently, the Union Railway Minister, in a written reply during the Winter Session of Parliament (December 2025), informed the Lok Sabha that the indigenously developed Kavach system has been fully commissioned on over 2,000 km of the Indian Rail network, with the rollout progressing at a very fast pace.
About Kavach System
Kavach is an indigenously developed Automatic Train Protection (ATP) system designed to enhance railway operational safety.
It has been developed by the Research Design and Standards Organisation (RDSO) under Indian Railways (IR) in collaboration with Medha Servo Drives Pvt Ltd, HBL Power Systems Ltd, and Kernex Microsystems.
Kavach is a highly complex digital safety ecosystem consisting of five major integrated components, including continuous Optical Fibre Cable (OFC) laid along tracks and telecom towers for uninterrupted communication.
The system uses a combination of electronic devices and Radio Frequency Identification (RFID) installed in locomotives, signalling systems, and railway tracks, which communicate using ultra-high radio frequencies.
Based on pre-programmed safety logic, Kavach can alert loco pilots, automatically apply brakes, and prevent unsafe train movements.
