There is "provision" for a railway station underneeath the multi story car park out the front. I think it's just a cavity with support columns and blanked off box tunnels at each end. Think of Box Hill without any track or platforms.
Yes David.......think that cavernous car park monstrosity at Cairns that replaced the "proper station"
As some of you boys and girls would know..........the easement to the south side of the old main goods lines between SSS and NME, that is, between the goods lines and Wara....Waradaringa?.....oh.....something like that......the roadway that replaced Footscray Road/Cowper Street on top of the old "East Yard" was "provided" (left for the railway) to eventually provide a right-of-way for the Sydney VFT an/or airport link.
Of course....after the financial disappointments of the Sydney and Brisbane airport lines, I'm not counting on seeing this within my remaining lifetime!
