Thanks for chiming in, YM.
I think today's pollies and key bureaucratic decision makers lack imagination and problem solving skills. This could be because back then, people had to manage with the limited resources available. Today, there is a phobia and paralytic hesitancy about decision making in general, and taking responsibility, even though we have never before had this volume of information available on demand, at our fingertips.
Why are simple things so difficult? Why was it easy to blow $100m in sports grants recently?
As I said before, if it can't be done by rail, then build another road. At least the pastoralists will have some benefit all year round.
