The Parramatta Light Rail (often unofficially referred to as the Western Sydney Light Rail) is a proposal for a twelve kilometre light rail line in Sydney, New South Wales, Australia, running from Westmead to Carlingford via the Western Sydney centre of Parramatta. The initial announcement of the project also included a branch from Camellia to Strathfield via Sydney Olympic Park, but plans to construct this branch were deferred in February 2017. The project will add to light rail in Sydney but the new line will be completely separated from the existing and under construction lines. The project is managed by the New South Wales Government's transport authority, Transport for NSW.
In 2013, Parramatta City Council published a $1 million feasibility study into a proposed Western Sydney Light Rail Network, designed to improve transport links throughout Western Sydney and meet the challenges posed by the projected rise in population in the region in the coming decades. The study found that a light rail system was a viable solution to address the growing transport needs of Parramatta and Western Sydney. The report proposed an estimated $20 million in state and federal support was required to undertake a detailed investigation and to prepare a business case. It proposed that construction of the network would take place in several stages, the first of which comprised a route from Macquarie Centre to Castle Hill via Eastwood, Dundas, Parramatta and Baulkham Hills, with a branch from Parramatta to Westmead. Further extensions were proposed from Parramatta to Bankstown and Rhodes.
