Project details

A joint venture between Thiess (50%) John Holland (25%) and Dragados (25%) was selected by the New South Wales Government to construct the tunnels and excavate new underground stations for Sydney’s visionary North West Rail Link.

Under the Tunnel and Station Civil Works contract, Thiess, John Holland and Dragados will construct twin 15 kilometre tunnels which will run between Bella Vista and Epping. These will be the longest rail tunnels ever built in Australia.

The project also includes civil works for five of the eight new stations and two service facilities. Four custom-made tunnel boring machines will be used to construct the 6 metre diameter tunnels.

The North West Rail Link will be a fully-automated rapid transit system, an Australian-first incorporating driverless trains and high-tech customer safety and security measures.

This project was originally awarded to Thiess. In June 2014, the Group announced it would establish dedicated businesses focused on contract mining, construction, public private partnerships (PPPs) and engineering. As part of this change, this project was transitioned to Leighton Contractors, our leading international construction contractor.
