H17 entered in service in May 1890 to operate construction trains, but by then the number 17 had been allocated to a G class locomotive, so it was renumbered H22.

[1] H22 was sold on 20 March 1907 to the Goldfields Water Supply Administration to operate the Mundaring Weir branch railway.

After the Marble Bar Railway closed on 31 October 1951, it was transferred to the Public Works Department for use as a shunter at Port Hedland.

[1][2] H18 transferred to the Goldfields Water Supply Administration in September 1904 for use on the Mundaring Weir branch railway hauling firewood and passenger trains.

In November 1911, it was transferred to the Public Works Department for use at Fremantle Harbour North Quay and later Esperance, and from 1926 on Bunbury breakwater construction and maintenance trains until it was withdrawn in the late 1950s.
