In the 1980s SMR No.25 became the last commercially operated steam locomotive in Australia. The coal railway worked by No.25 was closed in 1987 and the engine retired, but not before it was hijacked as part of a protest against the line's closure. It's at the Richmond Vale Railway Museum in Kurri Kurri, NSW.

Wee Georgie Wood was built in 1924 for a mining settlement that was so rugged and remote the railway was the only link to the outside world. Given the stage name of a popular British comedian, this small engine still entertains crowds today at the Wee Georgie Wood Steam Railway in Tullah, Tasmania.

R711 was commissioned in 1951 to haul Victoria's express passenger trains. Sleek, modern, and powerful, R711 had a short working life, being retired to stand outside Bendigo Railway Station in 1964.

W945 was introduced to the Western Australian Railways in the 1950s. Though primarily used as a freight locomotive W945 was also used to hault the Austriland from Perth to Bunbury.

No.504 was commissioned in the 1920s as part of an ambitious plan to upgrade the South Australian Railways. Designed to tackle steep climbs with ease, it went on to haul the famous Overland train for decades. No.504 is now proudly displayed at the National Railway Museum, Port Adelaide, on loan from the History Trust of South Australia.
