Which indigenous Automatic Train Protection (ATP) system has been developed by India to enhance railway safety ?
Kavach
Kavach is the indigenous Automatic Train Protection system developed by the Research Designs and Standards Organisation together with Indian industry partners, and it carries the national ATP designation for Indian Railways.
It works by exchanging data continuously between trackside RFID tags, station equipment and an onboard unit. If the loco pilot overshoots a signal at danger or exceeds the permitted speed, Kavach applies the brakes automatically, and it also prevents two trains on the same line from closing on each other.
The remaining names do not denote an ATP system. Tri-Netra is a fog and obstacle vision aid for loco pilots, Rakshak and Traintel are not Indian Railways ATP designations.
Hence, the answer is Kavach.
