NFR Installs Modern Automatic Block Signalling in Panjipara – Surjakamal Section of West Bengal to Strengthen Safety and Capacity

 Guwahati, 18^th May, 2026:

The Katihar Division of Northeast Frontier Railway (NFR) has successfully commissioned Automatic Block Signalling (ABS) in the Panjipara–Kishanganj–Hatwar–Kanki–Surjakamal section.

The newly commissioned ABS section spans approximately 30 kilometres and covers five stations, comprising three Electronic Interlocking (EI) stations and two Panel Interlocking (PI) stations. As part of the commissioning work, four Auto Signal huts have been provided to enhance signalling efficiency and operational safety.

A total of 14 level crossing gates fall within the section, out of which six gates have been newly, interlocked with the automatic signalling system for improved safety and smoother train operations. Additionally, 196 Multi Section Digital Axle Counter (MSDAC) detection points and 40 new automatic signals have been installed in the section.

 

The commissioning of Automatic Block Signalling will significantly enhance line capacity, improve punctuality and ensure safer and more efficient train movements in this important corridor under Katihar Division.

Northeast Frontier Railway has undertaken major signalling and safety enhancement works across its network in recent years. In 2025-2026 NFR has installed a total of 24 interlocked level crossing gates, replaced five Panel Interlocking systems with Electronic Interlocking, commissioned 22.29 Route Kilometre (RKM) of Automatic Block Signalling and installed 25 sliding booms at interlocked level crossing gates.

The successful completion of this major signalling upgrade is yet another important addition to enhance safety across the zone. In future, the system will be extended further up to Guwahati to enhance line capacity, safety and train operations. It reflects the continued commitment of Northeast Frontier Railway towards modernization of railway infrastructure, enhancement of operational efficiency and strengthening of safety standards across its network.
