Fitting of Q class flat wagons with special bolsters to carry pipes started in 1955. The converted wagons were reclassified QP. There were eventually 43 QP class wagons. The QPS class was created by the conversion of twenty QP class pipe bolster wagons in 1965. These were temporary and had all been reconverted to class QP by 1967. The WAGR outline diagram for class QP is shown below.

QPS 4480

After a period where wagons were written off, conversion from class QP to class QPS started again and class QP ceased to exist by 1976. A total of 36 wagons became class QPS. At least one of the QPS's seems to have run in its later years with no bolsters (3224 below).

The changes in and between the two classes are listed below
