They were tender locomotives, but also featured short boiler side tanks for additional water storage useful in the long distance required by operation on Western Australia's country lines. HistoryBetween 1896 and 1898, the WAGR took delivery of 36 O class locomotives from Neilson & Co with a further 10 built by Dübs & Co. They initially operated services on the Eastern Railway and on the South Western Railway to Collie before being superseded by the Ec and K classes and moving to branch line duties. In 1907/08, 10 O class were rebuilt as N Class suburban tank engines.[1][2][3] Between 1909 and 1912, Midland Railway Workshops built a further 10 as the Oa class. The last examples of the O class were withdrawn from service in 1962.[1][2][3] O218 has been preserved at the Western Australian Rail Transport Museum.[1][4] In April 2015, it moved to the Walkaway Station Museum on a five-year loan.[5] References1. ^1 2 {{cite book|last1=Whiteford|first1=David|last2=De Bruin|first2=Charles|last3=Watson|first3=Lindsay|last4=Watson|first4=Neville|title=Western Australian Preserved Locomotives|date=1983|publisher=Railmac Publications|location=Elizabeth|isbn=0 949817 19 8|page=11}} {{WAGR Locomotives}}2. ^1 {{cite book|last1=Gunzburg|first1=Adrian|title=A History of WAGR Steam Locomotives|date=1984|publisher=Australian Railway Historical Society|location=Perth|isbn=0 9599690 3 9|pages=52-55}} 3. ^1 {{cite book|last=Turner|first=Jim|title=Australian Steam Locomotives 1896-1958|year=1997|publisher=Kangaroo Press|location=Kenthurst|isbn=086417778X|pages=15, 48}} 4. ^[https://web.archive.org/web/20070712202713/http://www.railheritagewa.org.au/museum/frtloco.htm O Class] Rail Heritage WA 5. ^O218 arrives at Walkaway Walkaway Station Museum 5 : Dübs locomotives|Railway locomotives introduced in 1896|Steam locomotives of Western Australia|2-8-0 locomotives|3 ft 6 in gauge locomotives of Australia |
