History
TGR M class Garratt
In 1912, the Tasmanian Government Railways took delivery of two 4-4-2+2-4-4 Garratt locomotives from Beyer, Peacock & Co, Manchester. They were designed to haul express passenger trains between Launceston and Hobart. With the introduction of the R class, M1 was withdrawn in 1923 and sold to the Mount Lyell Mining and Railway Company while M2 was withdrawn in 1931 and scrapped in 1953.[1][2][3]
Namesake
The M class designation was reused by the M class that was introduced in 1952.
