The A/AA/AB classes have been used around the Westrail network, primarily on freight services, but with the occasional passenger work. Examples of their use include bauxite from Jarrahdale and iron ore from Westmine. Western Mining Corporation funded A1513-1514 for use on the latter service.
Most of the A class and one AB class have been bought by TranzRail to be used in Tasmania. As well, one A class, all of the AA class, and one AB class have been sold to Chile.
