The **MRWA P class** was a class of [steam locomotives](/source/Steam_locomotive) operated by the [Western Australian Government Railways](/source/Western_Australian_Government_Railways) (WAGR) and later the [Midland Railway of Western Australia](/source/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](/source/James_Martin_%26_Co), [Gawler, South Australia](/source/Gawler%2C_South_Australia). They were basically a [4-4-0](/source/4-4-0) version of the WAGR's 4-6-0 [G class](/source/WAGR_G_class), and identical to the [South Australian Railways Z class](/source/South_Australian_Railways_Z_class), save for a bogie tender in place of the SAR six wheel tender.[1] They entered service on the [Eastern Goldfields Railway](/source/Eastern_Goldfields_Railway) with P63 hauling the inaugural service from [Coolgardie](/source/Coolgardie) to [Kalgoorlie](/source/Kalgoorlie_railway_station) in September 1896.[2]

Both were sold in 1912 to the MRWA, however they were underpowered and after the delivery of its five new [C class locomotives](/source/MRWA_C_class), were relegated to shunting duties at [Midland Junction](/source/Midland_Junction_railway_station). In 1913, P62 commenced a 12-month lease to the [Public Works Department](/source/Public_Works_Department_(Western_Australia)). When it returned it was withdrawn and became a parts source for P63 which had been renumbered P12. Both were scrapped in 1929.[1][2][3]
