- (a) to (e): 1.    Kavach is an indigenously developed Automatic Train Protection (ATP) system. Kavach is a highly technology intensive

- system, which requires safety certification of highest order (SIL4).
2. Kavach aids the Loco Pilot in running of trains within specified speed  limits  by  automatic  application  of  brakes  in  case  Loco Pilot fails to do so and also helps the trains to run safely during inclement weather.
3. The  first  field  trials  on  the  passenger  trains  were  started  in February 2016. Based on the experience gained and Independent Safety Assessment of the system by Independent Safety Assessor (ISA), three firms were approved in 2018-19, for supply of Kavach Ver 3.2.
4. Kavach was adopted as National ATP system in July 2020.
5. Implementation of Kavach System involves following Key Activities:
- i. Installation of Station Kavach at each and every station, block section.
- ii.
- Installation of RFID Tags throughout the track length.
- iii.
- iv.
- Installation of telecom Towers throughout the section.
- Laying of Optical Fibre Cable along the track.
- v. Provision  of  Loco  Kavach  on  each  and  every  Locomotive running on Indian Railways.
6. Based  on  deployment  of  Kavach  version  3.2  on  1465  RKm  on South Central Railway and experience gained, further improvements were made. Finally, Kavach specification version 4.0 was approved by RDSO on 16.07.2024.
7. Kavach version 4.0 covers all the major features required for the

diverse railway network. This is a significant milestone in safety for  Indian  Railways.  Within  a  short  period,  IR  has  developed, tested and started deploying Automatic Train Protection System.

8. Major  improvement  in  Version  4.0  includes  increased  Location Accuracy,  Improved  Information  of  Signal  Aspects  in  bigger yards,  Station  to  Station  Kavach  interface  on  OFC  and  Direct Interface to existing Electronic Interlocking System. With these improvements, Kavach Ver.4.0. is planned for large scale deployment over Indian Railways.
9. After  extensive  and  elaborate  trials,  Kavach  Version  4.0  has been successfully commissioned on 738 Route km on  Palwal Mathura- Nagda section (633 Rkm) on Delhi - Mumbai route and Howrah-Bardhaman  section  (105    Rkm)  Delhi  -  Howrah  route. Kavach implementation has been taken up in balance sections of Delhi - Mumbai & Delhi - Howrah corridors.
