Kavach - ATP - Automatic Train Protection

 

Kavach - ATP - Automatic Train Protection


  • An indigenous ATP - Automatic Train Protection system

 

  • As part of TCAS - Train Collision Avoidance System  

 

  • Developed by RDSO - Research, Designs & Standards Organization, Lucknow in association with Indian Industry players.

 

  • Object: to boost safety in trains operations 

 

  • Kavach - literally means Protection or Shield  

 

  • How it works: It is a set of electronic devices and RFID - Radio Frequency Identification Devices installed in locomotives, in the signaling 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.  

 

  • Costing Rs.30 Lakh to 50 Lakh Kilometer (European Train Protection and Warning System costing approx Rs. 2 Crores per Kilometer.)


  • A part of AatmaNirbhar Bharat Abhiyan 

 

  • State of the Art electronic system. SIL - 4 certification.  Safety Integrity Level 4 certified technologies.  That means the probability of 1 error in 10,000 years. 

 

  • Chances of export of this Kavach technology for Railways.  

 

Salient features: 


  1. Prevention of SPAD - Signal Passing at Danger 

  2. Continuous update of Movement Authority with a display of signal aspects in Driver Machine Interface (DMI) / Loco Pilot operation cum Indication Panel (LPOCIP)

  3. Automatic Braking for Prevention of Over Speeding

  4. Auto Whistling while approaching Level Crossing Gates

  5. Prevention of collision between two Locomotives equipped with functional KAVACH

  6. SoS Messages during emergency situations

  7. Centralized live monitoring of Train movements through the Network Monitor System.

  8. Automatically reduced the speed to 30 Kmph from 60 Kmph as the locomotive entered the loop line.


Priority for introducing Kavach in Indian Railways


Priority

Routes

First

High-Density Routes of New Delhi - Mumbai and New Delhi - Howrah sections for 160 kmph with Automatic Block Signaling & CTC - Centralized Traffic Control

Second

Highly Used Networks with Automatic Block Signaling & CTC - Centralized Traffic Control

Third

Other Passenger High-Density Routes with Automatic Block Signaling

Fourth

All other Routes


  • 96% of railway Traffic is carried on Indian Railway High-Density Network and Highly Used Network routes.

 

  • 2022-23 FY Target: To cover 2000 KMs
