This Class B Tank Wagon model embodies virtually all the detail and features of the actual wagon and has been designed to fit on standard 00/H0 track.
Following publication of the British Railways Modernisation Plan in 1955, it became clear that future passenger and freight schedules would be revised and speeded up with the introduction of high-speed Diesel, Electro Diesel and all Electric locomotives.
Railway rolling stock would therefore be redesigned and constructed to operate within the conditions envisaged under the new modernisation programme. Whilst future railway planning covered the design and construction of all stock, including passenger and freight, no general provision had been made for railway tank wagons carrying petroleum products which normally did not operate at speeds in excess of 45 m.p.h. and were subject to frequent examinations during transit.
In 1956 British Railways designed a new tank wagon capable of maximum capacity on four wheels within the 35-ton gross weight permitted under high-speed conditions.
Three prototype wagons were designed and constructed. Following certain trials and shunting tests, British Railways approved the Mark 1.
Subsequently over 800 of this type of wagon were ordered from various builders. Two classes of vehicle were built, Class A for carrying petrol and highly inflammable products and Class B for carrying fuel oils, diesel oils and kerosenes.
The Class B type barrel is fitted with steam coils to assist the off-loading of heavy fuel oils. Discharge of the load is controlled by internal rod and plug, operated by the hand wheel located at the top of the tank barrel.
