HistoryThe first A class engine was ordered from Beyer, Peacock & Co, Manchester by John Robb, the contractor building the first section of the Eastern Railway between Fremantle and Guildford.{{sfn|Gunzburg|1984|p=19}} It arrived in Western Australia in 1880 and was similar in design to the South Australian Railways W class.[1] The WAGR acquired this locomotive upon completion of the construction contract in 1881 and numbered it 3 Other locomotives of the same design, were later purchased both new and second hand. When engine class designations were introduced in 1885, the locomotives became the A class.[2] When engine class designations were introduced in 1885, this whole group of engines became the A class. All but one of the 13 A class engines was built by Beyer, Peacock & Co; the other was built by Dübs & Co. Three had six-wheel tenders as opposed to four-wheel varieties.{{sfn|Gunzburg|1984|p=19}} The A class was used initially for main line passenger services, and later on branch lines. Some were sold to timber mills. The last was withdrawn in 1955, and two examples were preserved.{{sfn|Gunzburg|1984|pp=19 and 21}} A11 was placed on display at the Perth Zoo and is now with the Western Australian Rail Transport Museum, while A15 was plinthed in Bunbury and is currently under restoration in Meredith, Victoria.[1][3][4] NamesakeThe A class designation was reused in the 1960s when the A class diesel locomotives entered service.
