The network initially evolved from a privately operated system of feeder services to railway stations in the outer suburbs, and a publicly operated network of bus services introduced to replace trams in the inner suburbs. The bus network has undergone major reform in recent years, with the New South Wales Government taking responsibility for route and fare-setting, opening contracts for most routes up to competitive tendering, and introducing more cross-regional services.

Document 15: Wahgunyah railway line: The Wahgunyah railway is a closed railway line in the north-east of Victoria, Australia. Branching off the main North East railway at Springhurst, it ran north to Wahgunyah. The terminus was near the New South Wales Culcairn - Corowa railway, but no bridge was ever provided over the Murray River. As the two lines were of differing gauges and the stations 2.5 kilometres (1.25 miles) apart there was probably no particular benefit for the expense of building a bridge to connect the two differing systems.
