Kavach is a highly technology intensive system, which requires safety certification of highest order (SIL-4). 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: a. Installation of Station Kavach at each and every station, block section. --6/--6- b. Installation of RFID Tags throughout the track length. c. Installation of telecom Towers throughout the section. d. Laying of Optical Fibre Cable along the track. e. 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 1297 Route Kilometres, covering the high density Delhi- Mumbai and Delhi-Howrah routes. On the Delhi–Mumbai route Kavach ver 4.0 has been commissioned on Junction cabin-Palwal– Mathura–Nagda section (667 Rkm), Vadodara- Virar section (336 Rkm) and Vadodara - Ahmedabad section (96 Rkm), and on the Delhi–Howrah route Kavach ver 4.0 has been commissioned on Gaya Sarmatanr section (93 Rkm) and Howrah–Bardhaman section (105 Rkm). 10. Further, track side Kavach implementation work has been taken up on 23,360 RKM covering all GQ, GD, HDN and identified sections of Indian Railways. 11.

Specialized training programmes on Kavach are being conducted at centralized training institutes of Indian Railways to impart training to all concerned officials. By now about 48,000 technicians, operators and engineers have been trained on Kavach technology. This includes about 45,000 Loco Pilots & Assistant Loco Pilots. Courses have been designed in collaboration with IRISET. 14. The cost for provision of Track Side including Station equipment of Kavach is approximately Rs. 50 Lakhs/Km and cost for provision of Kavach equipment on locomotives is approximately Rs. 80 Lakh/Loco. 15. The funds utilized on Kavach works so far up to Dec'25 is Rs. 2,573.36 Crores. The allocation of funds during the year 2025-26 is Rs. 1673.19 Crores.
