Bachmann OO 38-778 National Benzol Class A 14T Anchor-Mounted Tank Wagon

Cylindrical tanks were mounted to railway wagon chassis by several methods, the mounting becoming steadily more robust as designs were developed. The anchor mounting uses strong central brackets to connect the tank section with the chassis solebars in the central portion of the chassis between the axles. This design was introduced in the 1930s and a large numbee of these anchor mounted oil tanks were built before and during WW2 for the air ministry. After WW2 these wagons were sold to the oil companies, so this design of tank wagon formed the primary post-war oil wagon fleet until larger 35 and 45 ton designs appeared in the 1960s.
