The Bikers begin their tour of industrial restoration projects by joining some ex-miners who are meticulously restoring Pleasley Colliery in Derbyshire. There is personal passion for Si as he helps to restore a steam winding engine, as his grandfather was a winder. Dave helps to celebrate 150 years of the London Underground by by putting Met 1, the tube's oldest working steam train, through its paces as it prepares to carry passengers a century after it went out of service. The Bikers also help fire up a barn engine on a Hampshire farm for the first time in 60 years and discover that the fairground was the last word in Victorian fun.
