On July 04, 2023 TBM Peggy began its journey at the future Airport Business Park Station, carving out the first 5.5-km sections of the second tube of the twin metro tunnels towards the Aerotropolis. The first TBM, named Eileen, started back in April.
TBMs Eileen and Peggy are now well into the ground, bringing metro services one step closer for Greater Western Sydney locals. TBM Eileen paid 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 m 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. 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.
