Western Australian Government Railways (WAGR) was the operator of railway services in the state of Western Australia between October 1890 and June 2003. Owned by the state government, it was renamed a number of times to reflect extra responsibility for tram and ferry operations that it assumed and later relinquished. Westrail was the trading name of WAGR from September 1975 until December 2000, when the WAGR's freight division and the Westrail name and logo were privatised. Its freight operations were privatised in December 2000 with the remaining passenger operations transferred to the Public Transport Authority in July 2003.

The Perth tramway network served Perth, the capital city of Western Australia, from 1899 until 1958. The network was initially run by a private company but was taken over by the state government in 1913. From a single line along Hay Street, the network expanded north as far as Osborne Park, east as far as Welshpool, south as far as Como, and west as far as Claremont. The tramways were gradually replaced by buses after World War II.
