The Cabramatta Loop Project will increase rail freight capacity on the Southern Sydney Freight Line by allowing freight trains travelling in either direction to pass each other. Together with the Botany Rail Duplication, it will build capacity to meet predicted growth in demand for freight to be carried on rail between Port Botany and metropolitan freight intermodal terminals.

The Australian Government announced in May 2018 a funding commitment to construct a freight rail passing loop between Cabramatta and Warwick Farm. Australian Rail Track Corporation (ARTC) is delivering the project on behalf of the Australian Government.

The project aims to:

  • Alleviate constraints on, and increase the capacity of, Sydney’s freight rail network to meet existing and future demands
  • Support the operation of intermodal terminals, including Enfield, Chullora and Moorebank
  • Encourage a shift in freight from road to rail, helping to reduce truck movements and associated traffic congestion.

Australia’s freight task is set to experience significant growth over the coming decades. The existing freight infrastructure cannot support this projected growth, with increasing pressure on already congested roads and rail lines through Sydney, and increasing use of heavy trucks.

About the project

The Cabramatta Loop Project includes the following key features:

  • New rail track – providing a 1.65 kilometre long section of new track adjacent to the existing track, with connections to the existing track at the northern and southern ends
  • Track realignment – moving about 550 metres of existing track sideways to make room for the new track
  • Bridge works – constructing two new bridge structures adjacent to the existing rail bridges over Sussex Street and Cabramatta Creek
  • Road works – reconfiguring Broomfield Street for a distance of about 680 metres between Sussex and Bridge streets.

Ancillary work includes communication, signalling and power upgrades, works to existing retaining and noise walls, drainage work and protecting/relocating utilities. In addition, new signalling will be installed at a number of locations within the rail corridor.

Major construction started in early 2022 and the project was commissioned in February 2024. Some finishing works are taking place, following commissioning.

The diagram below illustrates the key features of the project.

Project need

Efficient access to and from Port Botany is critical to the economic growth and prosperity of Sydney. Over the next 20 years, container freight, air freight, air travel and general traffic in and around the Port Botany area are expected to grow significantly. This will put more pressure on roads and other infrastructure and impact local communities. Without significant infrastructure investment, existing transport constraints and challenges will worsen.

The amount of container freight handled by Port Botany is predicted to significantly increase.  The NSW Freight and Ports Plan 2018-2023 predicts the amount of container freight handled by Port Botany to significantly increase, from 14.4 million tonnes in 2016 to 25.5 million tonnes in 2036, representing an increase of 77 per cent.  The Australian and NSW Governments have identified clear objectives to increase the share of this freight that is moved by rail.

The Southern Sydney Freight Line (SSFL) is already operating close to capacity, limiting its ability to adequately service future demands for rail freight transport. Additional demand arising from the predicted growth in container freight has the potential to exacerbate this situation, impacting on reliability and restricting the efficient movement of freight across the broader Sydney rail network.
