M and MA Class

Built by Robert Stephenson & Hawthorn in 1952, the ten M class initially worked trains of all types over the major lines in the north of the state. In 1957/58 four locomotives had their 4' 7" driving wheels replaced with surplus 4' 0" garratt wheels and were reclassified MA, to enable better operation on the North East Line (see table for numbers).

Although steam locomotive operation declined during the 1960’s, suburban and tour workings out of Hobart allowed most of the M and MA locomotives to stay in service, although M1, M2 and MA3 had been stored by the mid 1960s.

The 1971 TGR centenary celebrations, when six of the ten M/MA class locomotives (M3, M4, M5, M6, MA2 & MA4) were operational, was the finale for the type as a few months later all operational M/MA locos were withdrawn simultaneously. M3 was later reinstated to service and spent several years working tour and suburban passenger trains, before being withdrawn in October 1975.
