Wallerawang to Orange & Orange to Cookamidgera
The tender brief requires the track design be applied to allow trains to operate at an ideal track speed of 80 km/hr whilst minimising track lateral shifts or “pull” to avoid earthworks.
The work to be completed includes installation of permanent survey control marks to Map Grid of Australia coordinates, survey of existing rail track, track re-design and placement of track construction marks for tamping crews to "pull" the track to the design geometry.
Survey work commenced in November 2016 with final project document delivery in June 2017.
