5. 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.

6. Based on deployment of Kavach version 3.2 on 1,465 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.
