Project approval was received on 10 January 2017 with early works underway. The first of five tunnel boring machines will be in the ground before the end of 2018 to deliver new 15.5-kilometre twin railway tunnels between the end of Sydney Metro Northwest at Chatswood and Sydenham. New stations will be delivered at Crows Nest, Victoria Cross, Barangaroo, Martin Place, Pitt Street, and Waterloo along with new underground platforms at Central Station.

In 2024, customers will benefit from a new fully air-conditioned Sydney Metro train every four minutes in the peak in each direction with lifts, level platforms, and platform screen doors for safety, accessibility, and increased security.

The metro network will be fully segregated from the existing Sydney Trains network between Sydenham and Bankstown, improving the reliability of services on the line.
