NEW DELHI, June 30: Indian Railways has sanctioned a Rs 432 crore project to replace relay-based interlocking with Electronic Interlocking (EI) at 27 stations and cabins, including one Intermediate Block Signalling (IBS) location, on the High Density Network (HDN) and Highly Utilised Network (HUN) routes of the Asansol Division of Eastern Railway.
The sanctioned work includes replacing 28 relay-based interlocking installations — 27 Panel Interlocking (PI)/Route Relay Interlocking (RRI) systems and one IBS installation — with state-of-the-art Electronic Interlocking systems, significantly enhancing the safety, reliability and operational efficiency of train operations.
The project is part of Indian Railways’ ongoing modernization programme to provide Electronic Interlocking on HDN and HUN routes where advanced signalling technologies, including Kavach, Automatic Block Signalling (ABS) and Centralised Traffic Control (CTC), are being implemented.
Electronic Interlocking is a modern computer-based signalling technology that replaces ageing relay-based systems, offering greater reliability, quicker fault diagnosis, simplified maintenance and improved operational flexibility.
The project is expected to further strengthen railway safety while supporting higher line capacity and more efficient train operations on one of the busiest sections of the railway network.
Meanwhile, in another major infrastructure upgrade, Indian Railways has approved a Rs 200 crore project to provide a balance 48-fibre Optical Fibre Cable (OFC) network across the South Eastern Railway.
The project will establish 48-fibre OFC connectivity over 1,696.2 route kilometres across four major divisions of the South Eastern Railway, reinforcing the communication network that supports safe, efficient and technology-driven railway operations. (ANI)
