A total of 13 of them were built by Beyer, Peacock and Company in two batches. ==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 They were withdrawn from service between 1947 and 1955, and all were scrapped. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「WAGR M class」の詳細全文を読む スポンサード リンク
