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.
• Field trials have been ongoing since 2016 on passenger trains before large-scale deployment.
• As of December 2025, Indian Railways has:
  • Laid 7,129 km of Optical Fibre Cable (OFC)
  • Installed 860 telecom towers
  • Connected 767 railway stations to data centres
    Deployed trackside equipment along 3,413 km
  • Equipped 4,154 locomotives with Kavach
  • Around 40,000 technicians and operators have been trained, highlighting the technological sophistication of the system.
  • Consequential railway accidents have reduced by nearly 90%, declining from 135 incidents in 2014 to about 11 currently, indicating tangible safety outcomes.
