The WA class cold storage vans were the first new bogie cold storage wagons to be built for the W.A.G.R. since the W class of 1897. The were similar in design to the smaller EB class four-wheelers and a total of twenty-four were built (WA 23451- 23474). In 1963 two WA class wagons (23452, 23470) were modified to use mechanical refrigeration and reclassified WAR. The body was shortened in this process and the equipment mounted on a platform at one end. Four more new wagons of this type (23401-4) were built in 1965. The WAGR outline diagram for the WAR class is shown below. Three of the WAR class wagons became VT class filter vans (23401, 23452 in 1978 and 23403 in 1980). The rest were written off in 1986. WAR23470 was written back as class SC in 1988.
