The final tracks have been laid connecting the new Sydney Metro City and Southwest line with the existing Northwest line at Chatswood, completing a major component of the project.

Member for Willoughby Tim James said the Northern Connection is a 200-metre section of rail corridor connecting the northern suburbs to the Southwest.

“This major connection was constructed over two years with workers installing tracks and operational services in the 15.5-kilometre twin tunnels between Chatswood and Sydenham,” Mr James said.

“Six teams and more than 200 workers worked around the clock over one weekend to make the final connection. It was a mammoth effort.”

A rigorous testing and commissioning program along the new alignment will commence later this year, ahead of passenger services starting through the Sydney CBD in 2024.

New stations at Crow’s Nest, Victoria Cross, Barangaroo, Martin Place, Pitt Street and Waterloo, along with new underground platforms at Central Station will open next year.
