ANSWER
MINISTER OF RAILWAYS, INFORMATION & BROADCASTING AND
ELECTRONICS & INFORMATION TECHNOLOGY
(SHRI ASHWINI VAISHNAW)
(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
(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:
i. Installation of Station Kavach at each and every station, block section.
ii. Installation of RFID Tags throughout the track length.
iii. Installation of telecom Towers throughout the section.
iv. 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 1452 Route Kilometres, covering the high density Delhi- Mumbai and Delhi-Howrah routes
as below:
SN Section Progress (Route Km)
(1) Delhi-Mumbai route:
i Junction cabin – Palwal – Mathura – 667
Nagda section
ii Vadodara - Ahmedabad section 96
iii Vadodara - Virar section 336
(2) Delhi – Howrah route:
i Gaya Sarmatanr section 93
ii Chota Ambana - Bardhaman – Howrah 260
section
§10. Further, track side Kavach implementation work has been taken up on 24,427 RKM covering
all GQ,GD,HDN and identified sections of Indian Railways. The sections mentioned above also
pass through Kota division and state of Maharashtra.
11. Progress of key items of Kavach on High density routes including Delhi– Mumbai & Delhi–
Howrah corridors as on 14.03.2026 are as under:
SN Item Progress
i Laying of Optical Fibre Cable 8570 Km
ii Installation of Telecom Towers 1100 nos
iii Station Data Centre 767 Station
iv Installation of Track side equipment 6776 RKm
v Provision of Kavach in Loco 4211 nos
12. In addition, work for installation of Kavach in 8979 Locomotives and 1200 EMU/MEMU has
been taken up.
13. Specialized training programmes on Kavach are being conducted at centralized training
institutes of Indian Railways to impart training to all concerned officials. By now more than
55,000 technicians, operators and engineers have been trained on Kavach technology. This
includes about 47,500 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 Feb'26 is Rs. 2,763.90 Crores. The allocation
of funds during the year 2025-26 is Rs. 1673.19 Crores. Requisite funds are made available as
per the progress of works.
Protection of wild life: One of the innovative measures taken is development of AI-enabled
Intrusion Detection System (IDS) for detecting presence of elephants on Railway tracks using
Distributed Acoustic Sensors (DAS).
§The system components includes Optical Fibre, hardware & pre-installed signature of elephant
locomotion. The system is designed to generate alerts for loco pilots, station masters and
Control Room about the movement of elephants in proximity of railway tracks, for taking
timely preventive action. Presently, IDS system is working over 141 Route kms on critical and
vulnerable locations identified by forest department in the Northeast Frontier railway zone.
Works of IDS have also been sanctioned for identified corridors of 1088 Route Kms across
Indian railways covering NFR(403.42 Rkm), ECoR(368.70 Rkm), SR(55.85 Rkm), NR(52
Rkm), SER(55 Rkm), NER(18 Rkm), WR(115 Rkm) & ECR(20.3 Rkm).
