File:Sydney Metro TBM Nancy’s historic journey ends

Description
The first mega borer tunnelling under the centre of Sydney has finished work with the historic journey coming to an end at the new Barangaroo Station site.

Tunnel Boring Machine Nancy broke through a wall of sandstone, marking the end of a 15-month excavation to deliver Sydney’s newest metro railway tunnels.

Since launching from Marrickville in October 2018, Nancy tunnelled through 8.1 kilometres of sandstone and shale in a spectacular engineering feat deep under the centre of Sydney.
