New Delhi [India], June 30 (ANI): Indian Railways has sanctioned a project worth Rs 432 crore for the replacement of relay-based interlocking with Electronic Interlocking (EI) at 27 stations/cabins (including 1 IBS location) on the High Density Network (HDN) and Highly Utilised Network (HUN) routes of Asansol Division of Eastern Railway.

The sanctioned work includes the replacement of 28 relay-based interlocking installations (27 PI/RRI and 1 IBS) with state-of-the-art Electronic Interlocking systems, significantly enhancing the safety, reliability and operational efficiency of train operations.

The project forms 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 (ABS) and Centralised Traffic Control (CTC) 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.

Meanwhile, in a significant step towards strengthening the digital communication backbone of Indian Railways, Indian Railways has approved the provision of a Balance 48-Fibre Optical Fibre Cable (OFC) across South Eastern Railway at a cost of Rs 200 crore.

The project will provide 48-fibre OFC connectivity over 1,696.2 Route Kilometres (Rkm) across four major divisions of South Eastern Railway, reinforcing the communication network that supports safe, efficient and technology-driven railway operations. (ANI)
