WAGR W class

W class No. 953 at Bassendean Railway Museum in 2010 on display.

The WAGR W class were a total of 60 large steam locomotives operated by the Western Australian Government Railways (WAGR) from 1951 to 1972.

The W class were initially proposed by C.M.E. Frederick Mills in 1947, but his death in 1949 delayed the project. Beyer, Peacock & Coy of Manchester, England had already been advised of the design but identified multiple design flaws which they addressed in a meeting held in the UK in 1950.

Alterations included the firebox which was shaped to suit Collie coal which was notorious for its bad quality. Once they entered service, the W class could be found across the network on primary goods trains, though they did haul passengers as well, such as the Australind from Perth to Bunbury.

The reputation of the W class was good being depicted as strong and free-steamers with sound reliability. Minor teething problems and faults were attributed to poor welding resulting in no fewer than 34 W class laid up for repair at one point, though these issues had been eliminated by the late 1950s.

Withdrawals began in 1968 and ended in 1972 with the end of steam on the WAGR. 15 of the W class have been preserved with several in South Australia and one in the Northern Territory. They also make up the majority of the steam heritage operations on the Hotham Valley Railway in Dwellingup, Western Australia.
