TBM Wendy arrived at the site of Sydney Metro’s Crows Nest station, completing three kilometres of tunnelling from Chatswood.
TBM Wendy will spend several weeks undergoing maintenance before being re-launched at Crows Nest and tunnelling towards the next Sydney Metro station at North Sydney.
There are currently four TBMs in the ground, tunnelling the 15.5-kilometre twin railway tunnels from Chatswood to Marrickville.
Premier Gladys Berejiklian said TBM Wendy started digging in January and the project is making incredible progress.
“Once the next stage of this game-changing project opens there will be turn-up-and-go Metro train services to 31 stations along a new 66-kilometre railway,” Ms Berejiklian said.
