Tunnel Boring Machine Smashes Through At Future Western Sydney Airport Terminal Station
Western Sydney residents are one step closer to catching fast metro rail services, with TBM Peggy smashing through at the future Airport Terminal station in a major milestone for the Sydney Metro – Western Sydney Airport project.
The 1,066-tonne mega-machine completed the first leg of its 5.5-kilometre journey to the Aerotropolis, following TBM Eileen, who made her historic first breakthrough last month.
Peggy has worked around the clock at an average speed of 120 metres per week to build the fully lined 1.26-kilometre tunnel from the Airport Business Park, excavating around 112,000 tonnes of rock – enough to fill about 18 Olympic swimming pools.
In preparation for Peggy’s arrival, approximately 293,000 tonnes of rock (about 48 Olympic swimming pools) have been excavated from the 25-metre-deep Airport Terminal station box.
The enormous machine will now traverse the station box before being relaunched, to tunnel under the future Western Sydney International (Nancy-Bird Walton) Airport, with the TBM expected to arrive at the Aerotropolis metro station site in 2024.
TBM Peggy is named after Peggy Kelman OAM, an Australian aviation pioneer and adventurer.
Peggy Kelman was a friend of Nancy-Bird Walton, the namesake of the new international airport.
A total of four TBMs will build the 9.8-kilometre-long twin tunnels for the Sydney Metro – Western Sydney Airport railway line between St Marys and the Aerotropolis.
TBM Eileen is carving the metro tunnel alongside TBM Peggy from Airport Business Park to the Aerotropolis. TBM Catherine and TBM Marlene have begun their 4.3 - kilometre journey from Orchard Hills to St Marys.
A joint venture between CPB Contractors and Ghella was awarded the $1.8 billion Station Boxes and Tunnelling contract in 2021 to deliver 9.8 kilometres of twin metro tunnels, five station boxes and two services facilities shafts for the Sydney Metro – Western Sydney Airport project.
The line will be operational when Western Sydney International (Nancy-Bird Walton) Airport opens for passenger services in 2026, with an expected travel time of 15 minutes from St Marys metro station to the Airport Terminal Station and a further five minutes to the Aerotropolis Station.
Quotes attributable to Federal Infrastructure, Transport, Regional Development and Local Government Minister Catherine King:
“The spectacular arrival of TBM Peggy marks the fantastic progress underway on this vital 23-kilometre transport link, which will not only benefit Greater Western Sydney residents, but for those visiting from around the globe.
“We are thrilled to be shaping the future of this vibrant and growing region with reliable and fully accessible metro services, ready for when planes start taking off at the new Western Sydney International (Nancy-Bird Walton) Airport.”
Quotes attributable to NSW Transport Minister Jo Haylen:
“This city-shaping project is supporting the local economy with more than 14,000 jobs generated during construction, including 250 new apprentices and at least 20 per cent of the contract workforce coming from Greater Western Sydney.
“This project is making Western Sydney the doorway to the rest of the world, and we can’t wait to see it continue to take shape.”
Quotes attributable to Member for Werriwa, Anne Stanley:
“The community benefit, as the Western Sydney (Nancy – Bird Walton) International Airport continues toward completion, are immense.
Our residents are looking forward to the opportunities, jobs for the future, as well as the construction jobs which support families and the economy in Western Sydney."
