Rio Tinto—29,500 tonnes of iron ore—2.4 km, three locomotives
BHP Billiton iron ore train has typically 268 cars and a train weight of 43,000 tonnes carrying 24,200 tonnes of iron ore, 2.8 km long, two SD70ACe locomotives at the head of the train and two remote controlled SD70ACe locomotives as mid-train helpers[3]
BHP Billiton used to run iron ore trains of 336 car length, 44,500 tonnes of iron ore, over 3 km long, six to eight locomotives including intermediate remote unit. This operation seems to have ceased since the trunk line was fully double tracked in May 2011.[4]
The record-breaking ore train from the same company, 682 cars and 7,300 m long, once carried 82,000 metric tons of ore for a total weight of the train, largest in the world, of 99734 tonnes. It was driven by eight locomotives distributed along its length to keep the couplings loads and curve performance controllable.[5]
Leigh Creek coal—2.8 km, 161 wagons and 2 locomotives.[6][7]
Cane tramway – 75 wagons (610 mm (2 ft) gauge) [8]
