Rail transport in Australia is a crucial aspect of the Australian transport network. Rail in Australia is to a large extent state-based. The Australian rail network consists of a total of 41,461 km of track of three major track gauges, of which 2,940 km is electrified. Except for a small number of private railways, most of the Australian railway network infrastructure is government-owned, either at the federal or state level. Most railway operators were once state government agencies, but with privatisation in the 1990s, private companies now operate the majority of trains in Australia.The Australian federal government is involved in the formation of national policies, and provides funding for national projects. Rail transport in Australia has often been neglected in favour of the Australian road transport network.Rail dominates freight movements between Perth and the eastern states. Rail freight, mainly supporting commodity exports, is expected to jump by two-thirds by 2030,
