The journey from the CBD is expected to be around 30 minutes, but Transport Minister Jacinta Allan said the travel time would be confirmed in a detailed business case, due to be completed next year.

It would be integrated with the Metro Tunnel, allowing superior connection to more parts of Melbourne.
The $19.50 SkyBus has a travel time of between 30 and 45 minutes from Southern Cross Station.
Mr Andrews said the 12-kilometre route would cost between $8 billion and $13 billion, and could have private partnership.
He would not be drawn on how much a ticket would cost passengers, merely saying it would be as cheap as possible.
Construction will begin by 2022 if the Andrews government is re-elected.
Prime Minister Malcolm Turnbull said he was happy with the announcement.
“I have had a number of very good meetings with the Premier, Daniel Andrews, and I’m delighted that today he has confirmed that Victoria will commit the same amount of money, and I’m confident that … $10 billion will enable us together to build the rail line from Melbourne to Tullamarine airport.”
Following Mr Turnbull’s $5 billion commitment in April, Melbourne Airport said a rail link would “help us to realise the full potential” of the airport.
