The Tasmanian Government Railways M class was a class of 4-4-2+2-4-4 Garratt locomotives operated by the Tasmanian Government Railways.

History

In 1912, the Tasmanian Government Railways took delivery of two 4-4-2+2-4-4 Garratt locomotives from Beyer, Peacock & Company, Manchester. They were designed to haul express passenger trains between Launceston and Hobart.^[1] With the introduction of the R class, M1 was withdrawn in 1923 and sold to the Mount Lyell Mining & Railway Company while M2 was withdrawn in 1931 and scrapped in 1953.^[2]^[3]^[4]

The M class designation was reused by the M class that was introduced in 1952.
