History
The first batch of six engines, was built in 1911. This batch, which entered WAGR service in 1912, was only the third Garratt design to be built, and represented a significant step in the development of the type. The second batch, of seven engines, was built in 1913/14, and was designated as the Ms class because its members were superheated. One of the engines in the first batch was later fitted with a superheater and reclassified as an Ms class engine. All of the M/Ms class locomotives were used to haul trains on the WAGR's light lines. They were withdrawn from service between 1947 and 1955, and all were scrapped.Class lists
