The enhanced system, developed in-house, aims to prevent accidents, minimise human error, and ensure seamless train operations. According to officials, all locomotives equipped with earlier versions of Kavach will be upgraded to Kavach 4.0.

The North-East Frontier Railway has identified approximately 1,966 route kilometres, stretching from Malda Town to Dibrugarh, for implementation. This initiative is part of a broader strategy to modernise railway infrastructure and improve safety measures.

Kavach 4.0 integrates advanced features, including Station Kavach, which synchronises locomotive data with signalling systems, and RFID tags, installed along tracks to monitor train location and direction. These technologies work together to provide enhanced safety and smoother operations.

This move aligns with Indian Railways' ongoing commitment to reducing accidents and elevating passenger safety as part of its larger rail network strengthening plans.
