Having long watched the great public transport cities of the world quickly build and grow their rapid transit networks in recent years, Sydney will have three metro lines under construction at the same time come the 2020s:
1. Sydney Metro City and Southwest - Chatswood to Bankstown via North Sydney & Sydney CBD (completion due 2024)
2. Sydney Metro North-South Link - St Marys to Badgerys Creek Aerotropolis via Western Sydney Airport (completion due 2026)
3. Sydney Metro West - Parramatta to Sydney CBD via Sydney Olympic Park & The Bays Precinct (completion due late 2020s)
With the completion of these three railway lines (and other major transport projects such as Western Sydney Airport, WestConnex, NorthConnex, Parramatta Light Rail and Sydney Light Rail), Sydney will be a city transformed.
Deliver rail for the Western City
The Australian and NSW governments will deliver the first stage of a North-South Rail Link from St Marys to Western Sydney Airport and the Badgerys Creek Aerotropolis.
As a first step, the NSW Government will protect suitable corridors for future rail connections in Western Sydney. Both governments will contribute up to $50 million each to a business case process, in consultation with local government. This will include investigation of integrated transport and delivery options for a full North South Rail Link from Schofields to Macarthur and a South West Rail Link to connect Leppington to the Western Sydney Airport via an interchange at the Badgerys Creek Aerotropolis.
The Australian and NSW governments will be equal partners in funding the first stage of the North South Rail Link and have a shared objective to connect rail to Western Sydney Airport in time for opening, informed by the business case.
