In 1965 the WAGR acquired 12 flat top wagons from Commonwealth Railways as part of a job lot of 64 wagons. These had been R 48, R 64, R 65, R 68, R 356, R 369, F 884 (was R 43), G 241 (was R 241), G 247 (was R 247), TD 262 (was R 262), TD 280 (was R 280), SA 308. They became WSF 30601-30612.

In 1967 two wagons were converted to WSG. Six were sold to Goldsworthy Mining in 1971 and the remainder became class WSE in 1973.

A new WSF class appeared in 1979 when WSF 30163 was "converted from R" to became a rail winch wagon. Again presumably an ex CR wagon. In this case it would have been one of the ex Commonwealth Railways wagons bought in 1978 from ANR listed here. WAGR official view of WSF 30163 (RHWA collection)
