Steam Wagons, as roads became better the need for faster and effective transport became apparent.  While the Traction Engine was able to haul heavy loads the need for a more versatile method of transport was recognised by firms such as, Foden and Sentinel, both justly famed for the quality of their Steam Wagons. When fitted with pneumatic rubber tyres these vehicles transformed load hauling.  For the first time, fast long distance and local transport was a reality. Many of the Sentinel Wagons were capable of 60 m.p.h. this at a time when internal combustion powered lorry's were lucky to achieve 35 m.p.h. made the Steam Wagon "King of the Road" During the 1930's the method of calculating the Road Fund Licence was altered and was based on the wetted area of the boiler to the detriment of the Steam Vehicle.  Operating costs escalated, and the combination of improvements to the internal combustion powered vehicles together with their lower running costs resulted in the gradual disappearance of the Steam Wagon from our roads.
