The project involved the construction of six kilometres of new and upgraded track within the rail corridor between Epping and Thornleigh stations on the western side of the existing tracks.
The new (third) track separates northbound freight from all-stops passenger train movements along the steep incline between Epping and Thornleigh. This provides additional capacity for northbound (interstate container) freight trains, particularly during the daytime when passenger trains currently have priority.
Quickway were contracted to supply skilled labour to:
- Construct retaining walls
- Construct plinths for overhead wire structures
- Construct concrete protection slab
- Undertake steel fixing and formwork
