The Tasmanian Government Railways Q class was a class of 4-8-2 steam locomotives operated by the Tasmanian Government Railways.

## History

[edit]

In 1922/23, the Tasmanian Government Railways took delivery of six 4-8-2 locomotives from Perry Engineering, Gawler followed by a further three in 1929 from Walkers Limited, Maryborough. Between 1936 and 1945, a further 20 were built by Clyde Engineering, Sydney. The final four were delivered with higher pressure boilers.[1][2][3]

They operated on the Western, Derwent Valley, Main and Fingal lines. Following the arrival of the X class, they began to operate suburban passenger services in Hobart. The first was withdrawn in 1957 with the final examples withdrawn in January 1964 following the Y class entering service.[2] Q5 has been preserved at the Tasmanian Transport Museum, Glenorchy.[4]
