Mount Newman railway

The Mount Newman railway runs for 426 kilometres, from Newman to Port Hedland, and is one of Australia's longest private railways. The line, along with its spur lines to Mount Whaleback, Orebodies 18, 23 and 25, Jimblebar, Yandi and Area C, services the iron ore mines at Newman. It has the longest and heaviest trains in the world. The railway line was officially opened on 22 January 1969 by Premier David Brand.

Voice and data communications utilise a digitally trunked P25 VHF radio system and SDH transmission via either fibre or microwave linked repeater sites. The vast majority of remote repeater sites are solar powered with generator backup. The system is maintained by BHP Billiton Rail Communication Technicians based out of Port Hedland's Nelson Point and Newman.

All track side infrastructure such as wayside monitoring equipment, signals, switch motors, telemetry data and monitoring devices are solar powered and are monitored and controlled out of the Integrated Remote Operations Centre (IROC) in Perth.

The rail journey from Newman to Port Hedland typically takes about eight hours. The 268 car trains are 2.89 kilometres long, with each wagon carrying up to 138 tonnes.

At the end of 2012, BHP Billiton opened its new train control facility. All train control function now operates from Perth.

On 21 June 2001, the line broke the world record for the heaviest train as well as the longest train when a train weighing 99,734 tons and formed of 682 wagons ran for 275 kilometres between Yandi and Port Hedland. The train was 7.3 kilometres long, carried 82,000 tons of iron ore, and was hauled by eight GE AC6000CW locomotives.
