Most were built as Class A wagons for highly flammable products like petrol and aviation fuel, using the standard RCH 17'6" long 10' wheelbase chassis equipped with either side brakes and oil axleboxes. The 4275 gallon cylindrical tank was saddle mounted on transverse timber baulks and usually platforms were provided either side of a central filler hatch.
Tankers for less volatile class B products (eg tar) were usually fitted with heating tubes to raise the temperature of heavy oil products and persuade it to flow more easily and bottom discharge valves, were not permitted for class A products.
