The lines are now operational, following final works including installing turnouts, signalling works, and testing and commissioning new signalling infrastructure.
The combined projects are expected to deliver significantly higher freight capacity and fewer trucks on local Sydney roads.
Through Australian Government funding of $442 million, these transformative rail projects will together help meet future demand between Port Botany and metropolitan freight intermodal terminals, where the freight task is predicted to increase by 77 per cent by 2036.
The Botany Rail Duplication project duplicated the remaining 2.9-kilometre section of single line track between Mascot and Port Botany, including the construction of four new and replacement rail bridges.
The Cabramatta Loop Project provided a 1.65-kilometre section of new track adjacent to the existing track, allowing freight trains travelling in opposite directions to pass each other, and the construction of new bridge structures and track realignment.
