The Mount Newman railway, owned and operated by BHP, is a private rail network in the Pilbara region of Western Australia built to carry iron ore.

[1] The railway line was officially opened on 22 January 1969 by Premier David Brand.

[5] 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.

The train was 7.3 kilometres long, carried 82,000 tons of iron ore, and was hauled by eight GE AC6000CW locomotives.

[6][7] To operate construction trains, in December 1967, Mount Newman Mining purchased two Electro Motive Diesel F7 locomotives from Western Pacific Railroad; these were retired in 1971.

[9]: 353–35, 406–409 [12][13] The last of the unrebuilt 636s was withdrawn in February 1995 with 5497 preserved at the Port Hedland Machinery Park, 5499 by Rail Heritage WA[14] and 5502 by Pilbara Railway Museum.
