## (SHRI ASHWINI VAISHNAW)

(a) to (h): Safety is accorded the highest priority on Indian Railways. As a consequence of various safety measures taken over the years, there has been  a  steep  decline  in  the  number  of  accidents.  Consequential  Train Accidents have reduced from 135 in 2014-15 to 31 in the year 2024-25 as shown  in  the  graph  below.  The  causes  of  these  accidents  broadly include  track  defects,  Loco/Coach  defects,  equipment  failures,  human errors etc.

It may be noted that the consequential train accidents during the period 2004-14 was 1711 (average 171 per annum), which has declined to 31 in 2024-25.

Another important index showing improved safety in train operations is Accidents Per Million Train Kilometer (APMTKM) which has

reduced from 0.11 in 2014-15  to 0.03 in 2023-24, indicating an improvement of approx. 73% during the said period.

Consequential Train accidents on Indian Railways and causalities (including  railway  passengers  and  railway  personnel)  therein  are  as follows:-

| Period             |   No. of Consequential Train Accidents |   No. Of Deaths |   No. Of Injuries |
|--------------------|----------------------------------------|-----------------|-------------------|
| 2004-05 to 2013-14 |                                   1711 |             904 |              3155 |
| 2014-15 to 2023-24 |                                    678 |             748 |              2087 |

## The status of implementation of Kavach is as under:

- i) 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. ii) Kavach  aids  the  Loco  Pilot  in  running  of  train  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. iii) 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. iv) Kavach was adopted as National ATP system in July 2020.
- v) Implementation of Kavach System involves following Key Activities:
- a. Installation  of  Station  Kavach  at  each  and  every  station, block section.
- 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.
3. vi) Based on deployment of Kavach version 3.2 on 1465RKm on south central  Railway,  lot  of  experience  was  gained.  Using  that  further improvements were made. Finally, Kavach specification version 4.0 was approved by RDSO on 16.07.2024.
4. vii) 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.
5. viii) Major  improvement  in  Version  4.0  includes  increased  Location Accuracy, Improved Information of  Signal Aspects in bigger yard, 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.
6. ix) Progress of  Key  items  comprising Kavach  system  on  Indian Railways upto Feb' 2025 is as under: -

| SN.   | Items                                | Progress   |
|-------|--------------------------------------|------------|
| i     | Laying of Optical Fibre Cable        | 5743 Km    |
| ii    | Installation of Telecom Towers       | 540 Nos.   |
| iii   | Provision of Kavach at Stations      | 664 Nos.   |
| iv    | Provision of Kavach in Loco          | 795 Locos  |
| v     | Installation of Track side equipment | 3727 Rkm   |

- x) Next phase of Kavach implementation is planned as under:-
- a. Project for equipping 10,000 Locomotives has been finalized. 69 number  of  loco  sheds  have  been  prepared  for  equipping  with Kavach.
- b. Bids  for  track  side  Works  of  Kavach  for  approximately  15,000 RKm have been invited covering all GQ, GD, HDN and identified sections  of  Indian  Railways,  out  of  which  works  of  1865  RKm have been awarded.
4. xi) Currently,  3  OEMs  are  approved  for  supply  of  Kavach  System.  To increase capacity and scale of implementation, trials and approval of more OEMs are at different stages.
5. xii) Specialized training programme on Kavach are being conducted at centralized training institutes of Indian Railways to impart training to  all  concerned  officials.  By  now  more  than  20,000  technicians, operators and engineers have been trained on Kavach technology. Courses have been designed in collaboration with IRISET.
6. xiii) The funds utilized on Kavach works so far is Rs. 1950 Crores. The allocation of funds during the year 2024-25 is Rs. 1112.57 Crores. Further,  provision  of  Rs.  2000  Crores  has  been  made  for  Kavach work during the year 2025-26. Requisite funds are made available as per the progress of works.
