All rollingstock has been supplied by China Southern Rail in Zhuzhou, China. The ore waggons operate in married pairs, or slave/control configuration with F type couplers and drawbars between the pair riding on Amsted Super Service Ride Master bogies. These and all the other waggons are using NYAB overlay ECP and the Knorr Bremse tension spring park brakes.

Current operations involve train lengths of 2700 metres and consist of three locomotives and 232 married pair ore waggons with the consists operating with two ES44ACi unit hauling 116 waggons then another ES44ACi unit mid-train with a further 116 waggons. These loaded trains are banked by another pair of ES44ACi locomotives out of the Roy Hill mine (339 km) to the 307.9 km grade crossing.

Empty trains are usually timed to depart Tad Yard after a loaded has arrived and then planned to cross an opposing loaded train usually at Marubeni Loop located south of the Yule River approx. 152 km south of Port Hedland.

The railway has a total mainline length of some 346 km with the rail being supplied by both Nippon Steel and Sumitomo Metal Corp in Japan, and the concrete sleepers by Italian Thai DPC Ltd in Thailand.
The line 'starts' at the 0 km, being the car dumper at the port, with empty trains ending up at the -4.80 km on departure from the dumper balloon loop and then ends at the departure end of the loadout balloon loop, with the train loader at the mine located at roughly the 343 km.
Tad Yard is the marshalling service area for all rollingstock and motive power and located at the 8-13 km area and is of a triple track configuration about 4.5 km in length with the workshops, wheel lathe and fuelling facilities located to the immediate west of the marshalling yard.
The original construction rail welding yard is still in situ at the 21-23.5 km and is the home of the rail tester, track machines, ballast waggons etc. when not required down track.
Single ended ballast sidings are located at the:

  • Ballast siding A 44 km, points north; and
  • Ballast siding B 188 km, points south.

Single ended refuge spurs are located at the:

  • Refuge A 121 km, points south;
  • Refuge B 264 km, points south; and
  • Refuge C 315 km, points south.

The four passing sidings or loops are approximately 3200 metres in length are located at;

  • HPPL 75-79 km with a deal end backtrack off the north end of loop road;
  • Marubeni 152-159 km with a dead end backtrack off the north end of loop road;
  • Posco 228-231 km with a dead end backtrack off the north end of loop road; and
  • CSC Taiwan 290-293 km with a load backtrack at the north end of loop road.

Train Control is located in Perth and currently verbal train orders are issued over a digital TETRA radio network, with the system being very close to changing over to the Anslado cab based signalling system with moving block and is the first in the world that has specified a satellite-based train control system with a SIL4 (Safety Integrity Level 4) train localisation function at system level for train control.
