Shares, RES have to build their own line to connect to Transnet. however the Transnet line into the Waterberg, from Thabazimbi (big iron ore mine) is only a single track affair with limited signalling and a short passing loop halfway down the 120 km length. (only 50 truck trains can be passed and export trains are 100 truck)

It is this loop which restricts the number of trains slots and which I suggest RES should go and offer to extend. most of the civil work was pre done in the late 70's so its a matter of laying some rails.
