First Metro Tunnel TBM arrives in Melbourne

The first of 4 tunnel boring machines for the Metro Tunnel Project has completed its journey by sea to the Port of Melbourne.

Once assembled, the first TBM, which will be called Joan, will begin its journey at Arden Station site, drilling it’s way toward the western tunnel entrance in Kensington.

A second TBM, to be named Meg, is set to arrive in Melbourne by the end of next month, with 2 more to follow later in the year.

The enormous machines will support a crew of 14 workers, including a pilot directing the TBM on its journey through Melbourne’s underground. Each is manned 24 hours a day, 7 days a week as they bore through hard rock and sand at a speed of around 10m per day.
