Signalling System at N. F. Railway gets new phases of upgradation

N.F. Railway, towards its constant endeavour in making train journeys more safe and secure, continues to adopt technically advanced measures to upgrade and maintain track signalling system. The process is carried out in all five Divisions of NFR, i.e Tinsukia, Lumding, Rangiya, Alipurduar and Katihar, to avoid unprecedented incidents like accidents etc. NFR conducts several automated tests at signaling systems regularly by which human errors are checked and eliminated. Further, replacement and new installation along with up- gradations are implemented in signaling systems, when & wherever necessary.

As part of the initiative by the Indian Railways, NFR carried out various signalling up-gradation system at several divisional stations and sections. “System Integrity Test” of Electronic Interlocking/Panel Interlocking at Lanka station are carried and out of 4759 planned drawings, 4628 drawings related to Logic Interface, Cable Route Plan, Cable Termination Chart, Track Bonding Plan etc. are being completed as o­n January, 2024. NFR also carried out replacement of 3.260 Km signaling cable at Titabar, Furkating & Panitola railway stations under Tinsukia Division alongwith installation of 2.06 Km new signaling cable at Sabroom, Guwahati & Narengi stations under Lumding Division. Signal LEDs too were replaced with Integrated type LEDs at six stations i.e. New Karimganj, Karimganj, Dharmanagar of Lumding division, Nalbari of Rangiya division and Raiganj & Kaliyaganj stationsof Katihar division. Alteration in Electronic Interlocking is also carried out at Karimganj & New Karimganj stations in connection with commissioning of UFSBI between Karimganj-Mahishashan block section under Lumding Division

Railway signalling systems ensures the safe operations of trains, and their reliability and maintainability directly affects the capacity and availability of railway connectivity. Signalling refers to the communication system using signals to control train movements and provide information to drivers & operators. In contrast, interlocking is a mechanism that coordinates systematic function of signals, switches, and other equipments to prevent conflicting movements and ensure safe movement of trains.
