Kavach: Automatic Train Protection System

Kavach: Automatic Train Protection System

The Indian Railways tested ‘Kavach’-Automatic Train Protection System by making two trains move towards each other at full speed.

  • The Kavach system was announced in the 2022 Union Budget as a part of the Atmanirbhar Bharat initiative.
  • Around 2,000 km of rail network is planned to be brought under the indigenous system to enable safety and capacity augmentation in 2022-23.

Kavach:

  • It is India’s own automatic protection system, which is in development since 2012, under the name Train Collision Avoidance System (TCAS), which got rechristened Kavach or “armour”.
  • It is a set of electronic devices and Radio Frequency Identification (RFID) devices installed in locomotives, in the signalling system as well as the tracks.
  • They connect 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.
  • TCAS or Kavach includes the key elements from already existing, and tried and tested systems like the European Train Protection and Warning System, and the indigenous Anti Collision Device.
  • It will also carry features of the high-tech European Train Control System Level-2 in future.
  • The current form of Kavach adheres to the highest level of safety and reliability standard called Safety Integrity Level (SIL)4.
  • SIL comes from two voluntary standards used by plant owners/operators to quantify safety performance requirements for hazardous operations.
  • There are four SIL Levels (1-4). A higher SIL Level means a greater process hazard and a higher level of protection required.
  • In the new avatar, India wants to position Kavach as an exportable system, a cheaper alternative to the European systems in vogue across the world.
  • While now Kavach uses Ultra High Frequency, work is on to make it compatible with 4G Long Term Evolution (LTE) technology and make the product for global markets.
  • Work is on to make the system such that it can be compatible with other already installed systems globally.
