This project involved the upgrade of track on the Interstate network between Dry Creek and Gillman in Adelaide, which supports intermodal freight traffic to and from WA as well as a lot of heavy minerals rail freight. The upgrade will improve capacity by increasing rail size along the interstate line, moving rail size from 47 kg per metre to 60kg per metre and along with some other works will allow for higher axle loads (25 tonnes at 80km/h).
Quickway supported CR Rail to lead some of the track construction on this project. Track construction involved laying sleepers on rail and installing rail in 13m lengths adjacent to existing track. Existing track was then excavated beside, and skeleton track was put into place and welded. Plain track was done top ballasted and tamped to design heights and alignments.
The project also involved level crossing upgrades and turnout installations on loop roads.
