The '''MRWA P class''' was a class of [[steam locomotive]]s operated by the [[Western Australian Government Railways]] (WAGR) and later the [[Midland Railway of Western Australia]] (MRWA) from 1896.

==History== In July and August 1896, the WAGR took delivery of two steam locomotives from [[James Martin & Co]], [[Gawler, South Australia]]. They were basically a [[4-4-0]] version of the WAGR's 4-6-0 [[WAGR G class|G class]], and identical to the [[South Australian Railways Z class]], save for a bogie tender in place of the SAR six wheel tender.<ref name=gunzburg>{{Gunzburg-MRWA Locomotives|page=22}}</ref> They entered service on the [[Eastern Goldfields Railway]] with P63 hauling the inaugural service from [[Coolgardie]] to [[Kalgoorlie railway station|Kalgoorlie]] in September 1896.<ref name=Turner>{{cite book|last=Turner|first=Jim|title=Australian Steam Locomotives 1896-1958|year=1997|publisher=Kangaroo Press|location=Kenthurst|isbn=086417778X|page=6}}</ref>

Both were sold in 1912 to the MRWA, however they were underpowered and after the delivery of its five new [[MRWA C class|C class locomotives]], were relegated to shunting duties at [[Midland Junction railway station|Midland Junction]]. In 1913, P62 commenced a 12-month lease to the [[Public Works Department (Western Australia)|Public Works Department]]. When it returned it was withdrawn and became a parts source for P63 which had been renumbered P12. Both were scrapped in 1929.<ref name=gunzburg/><ref name=Turner/>{{sfnp|Gunzburg|1989|pages=22, 49}}
