Transport for New South Wales (TfNSW), the state transportation department, is delivering the largest transport infrastructure program Australia has ever seen, the A$41.4 billion Sydney Metro project over four years to keep Sydney moving. Sydney Metro comprises various stages, including: Northwest, City and Southwest, and West.
