Two 1066-tonne TBMs begin their journey on Sydney Metro’s Western Sydney Airport project, carving out the first 5.5km sections of the twin metro tunnels.

It’s full steam ahead on the Sydney Metro – Western Sydney Airport project, with tunnelling of the new 23-kilometre line now underway.  

Two 1,066-tonne tunnel boring machines (TBMs) Eileen and Peggy have started their journeys at the future Airport Business Park Station, carving out the first 5.5-kilometre sections of the twin metro tunnels towards the Aerotropolis. 

TBMs Eileen and Peggy are now well into the ground, bringing metro services one step closer for Greater Western Sydney locals.

As is tunnelling tradition across the world, these TBMs are named after women to bring luck to the workers who look to Saint Barbara for protection.

TBM Eileen pays tribute to the first female Mayor of Penrith, Eileen Cammack OBE, who also established the first pathology laboratory at Nepean District Hospital. TBM Peggy honours pioneer aviator Peggy Kelman OBE, who was instrumental in promoting female aviation and was a flying companion of Nancy-Bird Walton. 

The TBMs will excavate around 120 metres of tunnels per week, the first step in delivering the six new metro stations along the line from St Marys to the centre of the new Aerotropolis. 

This project will support more than 14,000 jobs during construction, including 250 new apprentices, with at least 20 per cent of the contract workforce coming from local communities.

The Sydney Metro – Western Sydney Airport line will be operational when Western Sydney International Airport opens for passenger services, with an expected travel time of 15 minutes from St Marys metro station to Airport Terminal Station and a further 5 minutes to the Aerotropolis Station.
