History

Between October 1893 and August 1898, the WAGR took delivery of 24 K class locomotives from Neilson & Co. They entered service on the Eastern Railway between Midland Junction and Northam. In 1902, they were displaced from this work by the F class. They then mainly operated freight services on the Collie line and within Perth, although they did operate Royal Perth Show and raceday special passenger services.

In 1915, two were repowered with superheated boilers. A further three followed, but all were converted back by 1937. Further reboilerings increased power output by a quarter.

Six examples originally intended for the WAGR were purchased by the British Government and sent to South Africa to ease a shortage being encountered by the Imperial Military Railways as a result of the Boer War where they became the C class.
