Why in the news?

Railway officials have said that the domestically developed Train Collision Avoidance System (TCAS) ‘Kavach’ was not in place on the route where the Andhra Pradesh train collision occurred.


About TCAS Kavach:

  • Kavach is an advanced cab signalling and train control system with built-in anti-collision features to enhance railway safety.
  • Kavach was developed by the Indian Railways Research Designs and Standards Organisation (RDSO) over ten years, starting in 2012.


Functions of Kavach: 

    • Acts as a guardian for the existing railway signalling system, ensuring enhanced safety.
  • Warning and Automatic Braking:
    • Alerts the locomotive pilot in the event of failing to recognize a ‘red signal.’
    • If the pilot does not slow down below 15 kilometers per hour after receiving warnings, Kavach takes control and automatically applies the brakes to bring the train to a halt.


Components of Kavach Infrastructure:

  1. Radio Frequency Identification (RFID) Technology: Installed in the tracks, using radio waves to identify objects and convey information wirelessly.
  2. Locomotive Equipment: Locomotive cabins have RFID readers, computers, and brake interface systems.
  3. Radio Infrastructure: Towers and modems are established at railway stations.


Working of Kavach Infrastructure:

  • The three components (RFID in tracks, locomotive equipment, and radio infrastructure) communicate with each other.
  • They constantly monitor train movements and transmit signals ahead to locomotives.
  • The system remains effective even in challenging conditions such as hilly terrain or poor visibility.
  • Direct communication between locomotives is established, sharing information about location and track IDs when multiple trains share the same track.
  • Locomotives use antennas to communicate with towers at railway stations, displaying warnings on the driver’s monitor.


Unique Features of the Kavach 
Cost Kavach is cost-effective, priced at Rs 50 lakh per kilometre, significantly cheaper than the European Train Control System (ETCS), which costs about Rs 2 crore worldwide.
Compatibility with Existing Infrastructure Kavach doesn’t replace traditional lineside signalling; it serves as a cab signalling train control system with anti-collision capabilities, enhancing existing infrastructure.
Comprehensive Coverage The Kavach program covers railway stations, signalling devices, and various train types, unlike the previous Auxiliary Warning System (ACD), which was limited to specific trains and locomotives.
Incorporation of Key Elements from Other Systems Kavach integrates elements from established systems like the European Train Protection and Warning System and the indigenous Anti Collision Device. 

Plans include features from the European Train Control System Level-2.

Future Compatibility Ongoing efforts aim to make Kavach compatible with 4G LTE technology and expand its application to global markets.
Safety Integrity Level (SIL) Kavach adheres to the highest safety and reliability standards known as Safety Integrity Level.


Cost of Deploying Kavach:

  • Deployment costs ₹50 lahks per kilometre for Indian Railways.
  • Current Kavach coverage is limited to 65 trains (1,500 kilometers), with potential for a lengthy implementation process. This amounts to only 2 percent of all trains in India. 


Funding Allotment for Kavach:

  • Indian Railways allocated ₹4,000 crore under the Signalling and Telecom budget head.
  • This budget may enable the implementation of Kavach on about 2,500 to 3,000 kilometres of railway tracks in the upcoming year.
