KAVACH System

In News

Recently the KAVACH System was showcased on South Central Railway .

About KAVACH System 

• ‘Kavach’ literally means armour, is an indigenously developed Automatic Train Protection (ATP) system by Research Design and Standards Organisation (RDSO) in collaboration with Indian industry .
• It is a set of electronic devices and Radio Frequency Identification devices installed in locomotives, in the signalling system as well the tracks, that talk to each other using ultra high radio frequencies to control the brakes of trains and also alert drivers, all based on the logic programmed into them.
• It is meant to provide protection by preventing trains from passing the signal at Danger (Red) and avoiding collision. 
  • It activates the train braking system automatically if the driver fails to control the train as per the speed restrictions. 
  • In addition, it prevents collisions between two Locomotives equipped with a functional KAVACH system.
• It is one of the cheapest, Safety Integrity Level 4 (SIL-4) certified technologies with the probability of error is 1 in 10,000 years. 
• Also, it opens avenues of export of this indigenous technology for Railways.
• Features of KAVACH
  • Prevention of Signal Passing at Danger (SPAD)
  • Continuous update of Movement Authority with display of signal aspects in Driver Machine Interface (DMI) / Loco Pilot operation cum Indication Panel (LPOCIP)
  • Automatic Braking for Prevention of Over Speeding
  • Auto Whistling while approaching Level Crossing Gates
  • Prevention of collision between two Locomotives equipped with functional KAVACH
  • SoS Messages during emergency situations
  • Centralised live monitoring of Train movements through Network Monitor System.
• Kavach’ will be deployed across the entire rail network beginning with 2,000 km in the 2022-23 fiscal and will be rolled out in 4,000 to 5,000 km every subsequent year,
