Tank wagons of this type were used extensively during the Second World War, some 6,500 vehicles passing to the Petroleum Board in September 1939 apart from over 3,000 in the Air Ministry Fleet. These first wagons were all class A vehicles, which were designed to carry 14 tons of liquids with a flashpoint less than 75 F, i.e. petrol and aviation spirit. Due to the Railway Clearing House regulations, discharge was by means of a siphon tube on the top of the barrel, as bottom discharge was prohibited at that time due to poor valve design. The tank has a capacity of 4,275 gallons.
