The 'Kavach 4.0' will be installed on the tracks in the Varanasi division of NER, which will curb everything from head-on collisions between trains to overspeeding.

To further strengthen train safety, Indian Railways has approved the installation of 'Kavach 4.0' on a 614.75-kilometer railway track in the Varanasi division of NER. This project will cost approximately ₹223 crore. Additionally, it will expand the indigenous Automatic Train Protection system to those sections of the Varanasi division where work is still pending.
