The period between the late 1800s and the late 1920s was the heyday of the road steam traction engine. Prior to that, 'portable' steam engines were pulled by horses from farm to farm to provide the power unit for belting to machinery for tasks such as the annual threshing. The invention of the self-moving traction engine brought many advances, always staying one jump ahead of amendments to the Locomotive Acts. Fairground operators hauled their huge road train of rides to the next fair; ploughing engines and threshing engines travelled from farm to farm; road hauliers carried huge loads; and steam rollers laid and mended the roads. The availability of cheap surplus First World War petrol vehicles saw road hauliers and fairground showmen dispense with the 'hassle' of operating steam vehicles, yet there were still manufacturers making steam wagons until the late 1930s and several councils carried on operating true steam rollers right into the 1960s.

Colin Tyson presents a vibrant selection of images celebrating traction engines in all their many and varied forms when 'steam ruled the roads'.
