Australia's National Railway Museum is the largest railway museum in Australia. More than 100 major exhibits, mainly from the South Australian Railways (SAR) and Commonwealth Railways and their successor, Australian National, are on display at its 3.5 hectares (8.6 acres) site in Port Adelaide, South Australia. The museum opened at Lipson Street in 1988 after 18 years at the SAR's former main locomotive depot at Mile End.
