Class QA Rail and timber wagons and QM class flat wagons

Westralia Ironworks turned built the first one hundred members of class QA in 1913 (9350-9440) and 1914 (9441-9). In 1929 9350 and 9384 were temporarily reclassified as class QD and fitted for the conveyance of oil tanks. A final batch of six (10064-10069) were built at Midland Workshops some years later in 1931.	QA9421
In 1934 QA 9370 was modified by the addition of strengthening beams outside the solebars in order to provide a wagon capable of carrying a power shovel. In 1942 it became a QM along with most of the rest of the QA class but returned to class QA in 1947. At some point it was reclassified QAS and was finally written off in 1979. The only wagon not converted to class QM in 1942 was QA9403.	QM9360

Re-conversion of QM class wagons to class QA was slow and some twenty wagons were written off as class QM. From 1962 QM9360, 9402, 9410 and 9434 were used for pick-a-back traffic. Class QM ceased to exist in 1983. In 1955 four QA class wagons were fitted with special bolsters for pipes and reclassified QAP. These four wagons were not in service in this form for very long as they were all reconverted to QA standard in 1957. In 1969 ten QA class wagons had their bolster removed and were fitted to carry four nickel ore containers each as class QAN. These were the last conversion of QA class wagons.
