AuRORa: Australian Rapid Overland Rail

The coastal corridor connecting NSW and Queensland's major cities, serving 12 million people along Australia's most densely populated route. Following the Pacific Highway corridor with coastal views from Newcastle to the Gold Coast.

Crossing the Great Dividing Range and the Barrier Ranges to connect Sydney with Adelaide via the mining hub of Broken Hill. HSR to Parkes, then upgraded conventional track shared with freight to Adelaide, replacing parts of the aging cross-country network.

Connecting Australia's two largest cities via the nation's capital, this is the most critical corridor in the network. The route serves 40% of Australia's population and would be the highest-frequency line, with trains departing every 30 minutes during peak periods.

Named for the Flinders Ranges and explorer Matthew Flinders, this line connects South Australia with Victoria's Gippsland region via Melbourne. The route serves the wine regions of the Barossa, the goldfields of Ballarat, and the agricultural heartland of western Victoria. Ararat station serves as the broad/standard gauge interchange point.

The transcontinental service: crossing the Nullarbor Plain to connect Australia's east and west coasts, replacing the Indian Pacific. This 2,700km route requires overnight sleeper services with upgraded track allowing 160-200 km/h operation on straightened sections. Intermediate stops at Merredin and other small towns provide necessary crew changes and passenger breaks on the long journey.

Western Australia's coastal connector, serving Perth and the southwest tourism region. This line would open up WA's wine country, beaches, and regional centers to rail access for the first time since the closure of regional passenger services in the 1980s.

The Red Centre route: Adelaide to Darwin via Alice Springs, replacing and upgrading The Ghan. Following the existing corridor but with track improvements allowing 160-200 km/h operation where viable. Sleeper services essential with potential day-long stops in Alice Springs for Red Centre tourism experiences.

The agricultural backbone: connecting regional centers from Victoria through NSW to Queensland without touching the coast. This line serves productive farmland, regional universities, and cities currently poorly served by interstate transport. Most economically viable non-coastal HSR corridor due to strong regional city populations.

Queensland's inland connector: from the Darling Downs through Brisbane and the coast to Rockhampton (HSR, shared with Capricorn Line), then upgraded conventional rail through the mining regions to Mount Isa. High-frequency coastal services transition to infrequent long-distance inland services. Small outback towns like Longreach and Winton provide necessary service breaks on the remote western section.

The tropical coast: Gold Coast to Far North Queensland via Brisbane and the Sunshine Coast. Crossing the Tropic of Capricorn, this line would connect Queensland's tourism destinations with its largest city, serving the Great Barrier Reef gateways of Townsville and Cairns. Named for the Tropic of Capricorn which the route crosses near Rockhampton.
