HistoryIn 1892 the Tasmanian Government Railways took delivery of six A class locomotives from Beyer, Peacock & Co, Manchester. A further two followed in 1902. In 1908, A2 and A4 were rebuilt with Belpaire boilers and enlarged fireboxes, five more followed between 1927 and 1932, with the last converted in 1946. They were relegated to lesser duties following the arrival of the R class in 1923. All were withdrawn in the 1950s after the X class entered service. Seven were scrapped in 1956 with A4 plinthed in Launceston City Park. In August 1990, it was acquired by the Don River Railway.[1][2][3][4] References1. ^{{cite book|last=Turner|first=Jim|title=Australian Steam Locomotives 1896-1958|year=1997|publisher=Kangaroo Press|location=Kenthurst|isbn=086417778X|page=45}} 2. ^{{cite book|last=Oberg|first=Leon|title=Locomotives of Australia 1850s-2010|year=2010|publisher=Rosenberg Publishing|location=Dural|isbn=9781921719011|pages=95/96}} 3. ^"Steam Locomotives of the Tasmanian Government Railways and its Constituents" Australian Railway History issue 917 March 2014 page 8 4. ^A4 Australian Steam 5 : Beyer, Peacock locomotives|Railway locomotives introduced in 1892|Steam locomotives of Tasmania|3 ft 6 in gauge locomotives of Australia|4-4-0 locomotives |
