Two become one: final connection made between Sydney Metro lines
02.02.2023
The final piece in the puzzle to connect Sydney Metro City & Southwest with the existing Metro North West Line has been completed, ahead of testing starting later this year.
Connecting these two metro lines brings turn-up-and-go metro services deep under Sydney Harbour and through the CBD one step closer.
From 2024, passengers can travel from Tallawong in Sydney’s north, into the city in under 50 minutes, Castle Hill to Barangaroo in 33 minutes and Chatswood to Martin Place in 11 minutes on a fast and reliable metro service.
The Northern Connection, linking the Sydney Metro City & Southwest line to the Metro North West Line was constructed over two years, including the installation of tracks and all operational services in the 15.5 kilometre twin tunnels between Chatswood and Sydenham.
The final connection of the two metro railways was made with four sections of rail and almost a kilometre of copper overhead wires between Chatswood Station and the new Sydney Metro City & Southwest tunnels.
Six teams and more than 200 workers worked around the clock over one weekend to make the final connection, completing a wide range of tasks including track laying, welding and grinding.
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.
