This UK video reveals how traction engines were developed from Cornish steam engines of the 1700s. It shows the world's largest beam engine in action, and explains in detail how it works. Going through the early attempts at mobilising agricultural engines, the programme arrives at the traction engine we all recognise.
Gary Wragg of the Hampshire County Museum Services explains how simple and compound engines work and shows how they are driven and used. A traditional boiler-maker shows how he continues to build and repair steam boilers.
