Project Description

Construction, testing, and commissioning of Centralised Traffic Control (CTC) systems and associated signalling infrastructure across 171 kilometres of operational railway. The project included upgrades to 10 passing loops and 11 level crossings, together with the installation of new signalling equipment, signal gantries, point machines for turnout installations, power supply systems, communications networks, and cable service routes.

Scope

The works involved significant civil, electrical, track, and signalling construction activities, including turnout installations, equipment foundations, location installations, signalling power infrastructure, and integration with the operational rail network. ASI delivered the testing and  commissioning of the upgraded systems to support increased network capacity, operational efficiency, and improved train control across the corridor.
