Demand for transport services in the corridor between Sydney CBD and Parramatta is high, and growing. This reflects high levels of employment and population growth along the corridor, and the corridor’s role as a conduit for servicing growing transport demand between Western Sydney and the Sydney CBD.
An extra 420,000 people are expected to move into the corridor between Greater Parramatta and central Sydney over the next 20 years, and more than 300,000 jobs are expected to be created in this corridor by 2036.
Future employment and population growth in the corridor will be driven in part by four key precincts: Parramatta, Sydney Olympic Park, The Bays precinct and Sydney CBD.
The 2015 Australian Infrastructure Audit projected that passenger demand on the existing T1 Western Line (which is more than a century old) would increase by about 50% between 2011 and 2031. Currently, the T1 Western Line moves around 40,000 people in the morning peak hour and is operating at 135% of seated capacity.
The initiative would provide a direct metro rail connection between the Parramatta and Sydney CBDs, linking communities not previously serviced by rail as well as supporting growth in areas between the two CBDs. This initiative has the potential to transform communities, create new ones and link them using a new state-of-the-art public transport system.
A new metro rail service would be able to move about 40,000 people an hour in each direction, and would work together with the T1 Western Line to service the growing needs of Western Sydney, effectively doubling the rail capacity of the Parramatta to Sydney CBD corridor.
The initiative would be integrated with long-term transport and land use planning for Western Sydney, including rail needs currently being investigated around the future Western Sydney Airport.
Since 2016, the NSW Government has been investigating alignment and station options for this corridor. These investigations will support the business case. In October 2019, the NSW Government announced a preferred alignment and station locations.
