The majority of these tank wagons were built between 1939 and 1944 as Class A wagons for aviation fuel using the 17ft-6inch long RCH chassis with a 10ft wheelbase, either side braking and split oil axle boxes. The tank was 7ft 2in diameter with a capacity of 4275 gallons saddle mounted to the underframe with two small platforms on the top of the tank. After the war as government control of oil distribution ended these tank wagons were distributed among the oil companies. Many were converted for carrying less flammable Class B products and fitted with bottom discharge valves and heating coils to help discharge of viscous oil products like bitumen.
All of the Class A tanks had gone out of service by 1971 with the last B Class tank following in 1973.
