South Australain Railways ordered the first 52 SHGX in 1969, being built by Mechanical Handling. These were painted yellow and placed on the standard gauge network in the north of the state. They were bogie exchanged to board gauge from early 1970's, and some were painted in SAR grey with the red piping shrike logo on the side. ( This is controversial, as there is also no photographic evidence released to suggest this, but the SAR rolling stock experts say some were painted grey, being seen at Mt Gambier and Wallaroo.)
When Australian National took over the SAR, they ordered another batch, 53-72. These were turned out in red. By the time the last batch was ordered. 73-108, their classification had changed to AHGX. These were painted in AN's new corporate green and yellow.
Auscision models produce a model of these wagons, in both discharge door styles, and as modified by ASR with roll tops. (As illustrated in the following photos)
