Rail electrification in Queensland

In the late 1970s and 1980s, a significant rail electrification program was completed in the Australian state of Queensland. The electrified Queensland network is the largest in Australia with over 2,000 kilometres electrified, the next biggest is New South Wales with 640 kilometres, that is served mainly as passenger operations.

An extensive network of freight lines are operated to service the Central Queensland coal networks is operated by Aurizon. The two networks are joined by the electrified North Coast line from Brisbane to Rockhampton, and the entire system is energised at 25 kV AC.
