As part of the Country Lines Improvement Program, Lycopodium assessed rail lines between Stockinbingal to Griffith, Narrabri to Walgett and Temora to Ungarie – totalling over 450km – for the suitability of upgrading the tracks to 25TAL.
The scope included track structure review, Preliminary Environment Assessment (PEA) and a Review of Environmental Factors (REF) as well as detailed assessment of all culverts, level crossings and turnouts within the scope area.
To perform the track structure review, Lycopodium developed a Power BI model to assess the rail, sleepers, ballast and formation, along with reviewing the maintenance history and track performance.
By undertaking this along with a customised formation design, both the longitudinal extent of works and scope of civil works were optimised to provide economical options for the upgrade scope.
