Mackex Services delivered overhead electrical infrastructure works for a section of the Australian Rail Track Corporation’s (ARTC) landmark Inland Rail project — Australia’s largest freight rail infrastructure programme at approximately $9.9 billion — providing HV connection and overhead electrical works along the North Star to Queensland border section traversing Essential Energy’s network area in northern NSW.
Works involved Level 1 ASP design and construction of overhead electrical infrastructure supporting the Inland Rail construction corridor, including overhead line relocations where the rail alignment conflicted with existing Essential Energy distribution network assets, installation of new HV supply connections to construction compounds and operational infrastructure, and coordination of network switching for construction phase supply arrangements across a 30-kilometre section of the project.
Working on a nationally significant infrastructure programme in remote northern NSW required extensive mobilisation and self-sufficiency planning. The project’s scale and geographic extent across Essential Energy’s rural network required close coordination with network operations for multiple planned outages and switching events. Overhead line relocations required precise survey work to establish new alignment options compatible with both the rail corridor and Essential Energy’s network design standards. Works were performed in a high fire danger region during a critical construction phase requiring strict ignition management protocols.
