Steam wagons steam engines that carry goods on the roads developed considerably later than traction engines and steam rollers, which had started to appear in the mid 1860s. This book tells the story of steam wagons from the earliest designs through to the last models. It explains how they worked and what they did. An informative text is combined with a selection of photographs to illustrate steam wagons both at work in their heyday in the early twentieth century and in action more recently in the period in which they have become valued historical artefacts.
