completely random guess, but QRN?
Would be the most obvious, but speaking to someone in the know a few weeks back and they said unlikely. I think QRN are looking for something a bit bigger.
Didn't QRN buy part of the Dry Creek yard on their acquisition of ARG?
I've never been clear which bit.
Apparently QR can exercise an 'option' to take over Dry Creek south (which I think includes our existing GWA ex-AN office building and carpark) and plans have been circulated for a rather fancy intermodal yard on the site. I have no idea if anything has actually happened in that regard though.
As for the SCT site, I think SCT was waiting until the Sturt Highway 'diversion' aka the M20 aka Northern Expressway was more or less completed along with full commissioning of the extended Bolivar crossing loop before they kicked off work building the new facility.
No doubt all the people utilising the land SCT owns at Direk for rural purposes have now been (or are in the process of being) turfed out.
I am a bit concerned that even though the new road is designed to 'remove' trucks, etc. from the A20 south of Gawler West and funnel them all into the soon-to-be-completely-flooded Port Wakefield Road, Heaslip road will have much more truck traffic when SCT's new site is operating.
