SC Seeks Status Report On Implementation of Kavach

Context:

Recently, The Supreme Court of India gave the Centre four weeks to file a status report on measures taken to implement ‘Kavach’, an automatic train protection (ATP) system.

The death of over 288 passengers in the ghastly train accident on June 2 at Bahanaga Bazaar railway station in the Balasore district of Odisha has brought into sharp focus the safety mechanisms needed to prevent such tragedies.

Relevance:

GS III: Science and Technology

Dimensions of the Article:

  1. Kavach System: An Indigenously Developed Automatic Train Protection (ATP) System
  2. Applications

Kavach System: An Indigenously Developed Automatic Train Protection (ATP) System

  • Developed by the Research Design and Standards Organisation (RDSO) under Indian Railway (IR).
  • Collaboration with Medha Servo Drives Pvt Ltd, HBL Power Systems Ltd, and Kernex Microsystems.

Components and Communication:

  • Consists of electronic devices and Radio Frequency Identification (RFID) devices.
  • Installed in locomotives, signaling systems, and tracks.
  • Communication between devices using ultra-high radio frequencies.
  • Logic programming enables control of train brakes and driver alerts.

Field Tests:

  • Railway conducted field tests for Kavach since 2016.
  • Tests carried out on passenger trains.

Applications:

  • Assisting locomotive pilots in avoiding Signal Passing At Danger (SPAD) and overspeeding.
  • Alerting loco pilots and automatically applying brakes to halt the train when another train is detected within a set distance.
  • Continuous relay of signals ahead for better visibility in low-visibility conditions.
  • Automatic speed control by applying brakes if the loco pilot fails to do so.
  • Supporting train operations during inclement weather, like dense fog.
