Two tunnel boring machines have arrived at the Sydney Metro West Project, in preparation for the construction of 11km long twin-tunnels connecting Greater Parramatta to the Sydney CBD, complementing new excavation works for the new Sydney Olympic Park Metro Station.
The $12.4 billion Sydney Metro West line, measuring 24km once built, will provide a transport link to the growing communities of Western Sydney.
The tunnel boring machines (TBMs) include refurbished parts from the mega boring machines used on the Sydney Metro City & Southwest project. The cutterheads, front shields and gripper shields were originally used for the TBMs that dug the metro tunnels from Chatswood to Blues Point.
Once launched, the newly arrived TBMs will excavate an average of 200m per week, with around 15 workers per shift operating each TBM 24 hours a day, seven days a week.

New South Wales Premier, Dominic Perrottet, said Sydney Metro was Australia’s largest public transport project.
Our Government is transforming the way that people move around Sydney, investing more than $76 billion in transport infrastructure across the state, including more than $16 billion in Western Sydney alone,” Mr Perrottet said.
“The centrepiece of this investment is Sydney Metro, the biggest public transport project in Australia.
“Work is now underway to excavate 468,000t of rock and soil – the equivalent to 78 Olympic swimming pools – to make way for a state-of-the-art metro station at Sydney Olympic Park.
“This new transport link will further reinforce Sydney Olympic Park’s status as a premier events, sporting, and entertainment precinct, supporting the transit of more than ten million people who visit or stay each year.”
New South Wales’ Minister for Transport, Veterans and Western Sydney, David Elliott, announced that two mega tunnel boring machines are now on site at The Bays.
“Two mega tunnel boring machines located at The Bays have the important job of carving out 11km twin tunnels from The Bays to Sydney Olympic Park, bringing Sydney’s booming west one step closer to a world-class rapid metro system in their own backyard,” Mr Elliott said.
“When passenger services start in 2030, Sydney Metro will open the door for more people to explore this dynamic destination, providing a major boost for the area.
The TBMs are due to start tunnelling from The Bays in the first half of 2023 and will arrive in Sydney Olympic Park in late 2024.
Excavation of the station is expected to take around thirteen months to complete and will include the installation of 114 active anchors and 467 passive bolts, and 2151 rock bolts to support the station box structure, as digging progresses to a depth of around 27m.
The excavation work has started on the station boxes for Sydney Metro West stations at The Bays, Burwood North and Sydney Olympic Park. The first tunnel boring machine will arrive at Sydney Olympic Park in late 2024.
The tragedy is that it is $12.4 billion project in the wrong place and not directly linking the major CBD centres of Parramatta and Sydney. It will not provide public transport for western Sydney residents to access the airport as they are located in 5-6 different centres all of which are 15 or more kms away and will have good road access and plenty of parking. This is a clear case of decision making by politicians for “virtue signaling” purposes and has nothing to do with making both the new airport and its adjoining new employment zone successful
The whole point of the Metro West is to link the City to Parramatta in 20 minutes mate – there will also be a metro for the Western Sydney Airport too
Peter Thornton – Have a look at a map of Sydney Metro West. It pretty much starts at the center of the Sydney CBD on the corner of Hunter and George streets and goes through the center of the Parramatta CBD.
Maybe you are confusing the Sydney Metro West and the Airport Metro (since you seem to mention that too)?. Seperate projects.
