An excellent model from Dapol of the iron bodied gunpowder van, complete with red cross hazard marking to warning staff that the contents may be dangerous and the van should be shunted carefully. Due to the robust construction some of these vans remained in service safely moving explosives until replaced in the 1980's.
Gunpowder vans were used for the transport of many types of explosives, ranging from early powders to later dynamite and the more stable gelignite. The vans were also used for military traffic, including the delivery of small consignments of ammunition, live and practice, for the use of Territorial Army, reserve units and Army/Navy/Air Force cadet units. A good reason for one single wagon of 'explosives' to arrive at any railway station from time to time.
