North West Rail Link


North West Rail Link is a current project by the Government of New South Wales for a heavy rail rapid transit link to the north-western suburbs of Sydney, Australia. It will connect Rouse Hill to Epping via Castle Hill. The project is being managed by Transport for New South Wales and will form part of Sydney's rapid transit network. In June 2013 it was announced that a joint venture between Thiess (50%) John Holland (25%) and Dragados (25%) (TJHD JV) had been 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 $1.15 billion Tunnel and Station Civil Works contract, TJHD JV 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 with the first of the TBMs to be in the ground by the end of next year.

Stations will be located at: Cherrybrook, Castle Hill, Showground, Norwest, Bella Vista, Kellyville, Rouse Hill and Cudgegong Road. Also planned are 4,000 commuter car parking spaces. Driverless trains will be operated on the line when it opens.

In November 2013, Kenny Constructions were awarded the contract to form the large precast facility at Bella Vista. With casting of the >30,000 precast segments due to commence in April 2014, the works from of the overall project critical path.
