The northbound Sydney Trains track in New South Wales (NSW), Australia, has been moved to connect with new tracks located 20m to the west to accommodate the Metro North West Line, which will extend into the new twin metro tunnels.
The Sydney Trains T1 North Shore Line has been permanently rearranged between Artarmon and Chatswood.
The realignment process was undertaken as the current suburban railway tracks were obstructing the new Sydney Metro.
NSW Minister for Transport and Roads Andrew Constance said: “We’ve essentially picked up and moved one of Sydney’s oldest and busiest railway lines, which was an amazing feat of engineering and required incredibly hard work from the 250 local workers involved.”
The local workers executed the trackwork at Chatswood, enabling Sydney Metro to extend from the city’s north-west into the Sydney CBD and to Bankstown.
The realignment operation, which involved the process of cutting, slewing and joining the current suburban line, was concluded in 48 hours.

Thereafter, nearly 900m of new track and 2.5km of new overhead wiring were placed as part of the operation.
Under the Sydney Metro City and Southwest project, approximately 11km of track and more than 10,000 railway sleepers have so far been deployed.
Subsequently, nearly 62km of Australian-made rail steel will be utilised to lay 31km of railway tracks in the twin tunnels between Sydenham and Chatswood.
Sydney Metro rail services between Chatswood, the Sydney CBD and Bankstown are expected to commence in 2024.
After completion, Sydney will have a 66km standalone metro railway system, along with 31 Metro railway stations.
Earlier this month, Australia’s NSW Government had shortlisted three consortia to execute the new metro railway line tunnelling works, which will operate between Greater Western Sydney and the new Western Sydney International (Nancy-Bird Walton) Airport.
The qualified entities included the John Holland Gamuda joint venture (JV), Bouygues Construction Australia and Acciona Construction Australia.
