Frank, from what I read the Queensland Nickle site and mine were only from the 1970s, I assume therefore the line SSW which crosses the main line was only built then? Which means I can delete that leg and save some work. Also was Kulburn Station on the main line or did it include a siding? I won't be buying any more plans as that $56 Morrison siding was a one sheet plan with the single main line and one small passing loop, and nothing else! Turns out its' just passed where I plan to stop at Rollingstone, which during WW2 provided extra water for Townsville, carted by tankers on the railway. The southern leg (to Mt Isa) stops just passed Woodstock so I can include the first airfield there.
From about Campoven Creek there seems to be errors between the grades and google earth, as the land rises up and down where-as street view clearly shows it's almost dead flat. I'm having to fudge the grades a number of times! Saltwater Creek seems to have about the only steel girder bridge I've found so far.
