THE New South Wales (NSW) government is considering business cases for four new metro lines in the west of Sydney to improve public transport and access to the new Western Sydney Airport.

The government will spend $A 260m ($US 181.6m) on the final business cases for the new lines, which, if approved, will total 100km.

The first line would run from the terminus of the North West Line at Tallawong to St Marys, where it would connect with the under-construction Western Sydney Airport Line. A second line would run from Bankstown, the southern terminus of the under-construction metro network, via Liverpool to Glenfield.

There would be another two metro lines from Westmead and Macarthur, both running to Western Sydney Airport, which is scheduled to open in 2026.

Work on the four new lines, if they are approved, would start this year although this could be dependent on the incumbent state government, which announced the plan, winning next month’s state election.

The proposed new metro lines will be integrated with the wider Sydney Metro network, where the North West Line from Chatswood to Tallawong was the first to open in 2019. An extension to Sydenham will open next year, followed by a further extension to Bankstown within 12 months.

The state government is also promising that the Sydney Metro West project will be completed by 2030 to connect Westmead and Parramatta with the city centre via Sydney Olympic Park and Canada Bay.
