For SE QLD, do a bit of a search on Bromelton Industrial Precinct, PN, ARTC and SCT own huge plots of land on each side of the Interstate Rail Line, already upgraded to DG to Acacia Ridge. ARTC plans to have the IR use that section of track to go to Bromelton and Acacia Ridge. There is heaps of space on these lots for intermodal depots and enormous warehousing facilities for any customer's rent money.
On the point of Coal, the QLD Gov wants to divert the western coal away from the pas rail network to run on this future section of IR from Toowoomba to ACR. That combined with the POB pushing for a connection to it from IR as well, ARTC is indeed focusing on what customers want, not the rail operators.
