The waiting game for a pair of electric-powered 3'6" gauge (1067 mm) trains - one operated by BHP Billiton Mitsubishi Alliance (BMA) and the other by line owner, Aurizon. Both railroads have trains led by Siemens E40 AG-V1 electrics, BMACC 013 and Aurizon 3704, as they await their turn to go north to Hay Point for unloading. In the distance are the DPUs positioned every 40 cars in the 125 car trains.
