New South Wales Transport and Infrastructure Ministry has revealed design plans for the Showground station site, which is one of the eight railway stations for Sydney's A$8.3bn ($6.41bn) North West Rail Link (NWRL) project.
The first of four tunnel boring machines (TBM), Elizabeth, has broken ground at the site, indicating that tunnelling for the project is more than a third complete.
The underground station will have platforms nearly 20m below the surface. It will provide access to the existing Castle Hill Showground residential development, as well as nearby employment areas.
Design for the station was revealed by NSW Premier Mike Baird and NSW Transport and Infrastructure Minister Andrew Constance.
It will feature a domed glass and steel roof, a public plaza and new retail space, reports The Daily Telegraph.
Constance said: "The North West Rail Link is the first stage of Sydney's new rapid transit railway system and will provide a significant boost to capacity across the network.
"From the end of the project at Chatswood, rapid transit services will continue under Sydney Harbour, through new stations in the CBD and west to Bankstown."
Elizabeth started tunnelling at the project in September last year, four months ahead of the scheduled date.
The TBM is presently halfway through its 9km destined path from Bella Vista to Cherrybrook.
Services for the North West Rail Link are expected to start within the initial six months of 2019.
