Also, the gantries and overhead lines could not be installed without at times closing the line to Port Hedland, adding massive amounts of lost revenue to the financial burden of the high capital cost.
I hope these companies also consider the idea of working together abd relying on each other to cover costs of an electrification roll-out up there.
If one line is down how feasible is it for them to travel along another company's line,
or, have a profit/revenue share deal for the times each company's lines have to be closed for electrification thereby ameliorating the individual one time costs across the network of Pilbara iron ore miners. A deal like this would probably be more atteactive to government supports as well, as it supports industry and not single companies.
