In 1988, 50 hoppers (originally coded PIA, then KPA) were built for Tiphook Rail in response to growth in the construction industry. They saw service around the network with Tarmac, RMC and Foster Yeoman, among others. In the mid 1990’s, experimental discharge gear was fitted to enable them to operate in five-vehicle sets as Autoballasters, in place of ageing Seacow and Dogfish wagons. The success of the project saw further conversions, and the purchase by Railtrack and subsequently Network Rail of considerable numbers of new wagons to an almost identical design.
