It would work as follows:

1) FMG allows AGO to use the rail for a fee per tonne on the proviso it ships say 50Mt per year (random higher number);

2) If this can not be achieved then AGO would be required to purchase Iron Ore from FMG at market rates to make up the difference.

This achieves rail and port solution for AGO as well as FMG additional ore and also complys with current port restrictions.

They could also somehow factor FMG acquiring a minor interst in the H2 mines. They were looking for a JV from memory.
