Indian Railways has sanctioned a project for the replacement of relay-based interlocking with Electronic Interlocking at 27 stations or cabins on the High Density Network (HDN) and Highly Utilised Network (HUN) routes of Asansol Division of Eastern Railway. The Ministry of Railways said that the sanctioned work includes the replacement of 28 relay-based interlocking installations with state-of-the-art Electronic Interlocking systems, significantly enhancing the safety, reliability and operational efficiency of train operations.

The cost of the project is over four hundred crore rupees. The project is part of Indian Railways’ ongoing programme for the provision of Electronic Interlocking on HDN/HUN routes where advanced signalling systems such as Kavach, Automatic Block Signalling and Centralised Traffic Control are being implemented.

Electronic Interlocking is a modern signalling technology that replaces ageing relay-based systems with computer-based interlocking, ensuring higher reliability, faster fault diagnosis, easier maintenance and enhanced operational flexibility. The project will further strengthen railway safety while supporting higher line capacity and more efficient train operations on one of the busiest sections of the network.
