Guy Martin: Industrial Wonders

Birmingham Botanical Gardens may seem an unlikely place to explore the wonders of the Industrial Revolution, but hidden behind its fragrant borders Guy Martin finds a hidden world of hi-tech Victorian engineering, show-off architecture, intrepid plant-hunters scouring the furthest corners of the Empire, and city fathers terrified of the 'degenerate' urban poor. As Guy helps to get the gardens back into shape, he tries to learn one of the Industrial Revolution's most skilful and dangerous jobs: blowing glass for the gardens' enormous greenhouses.

Guy helps restore the oldest surviving Brixham sailing trawler, the boat that launched the modern fishing industry and transformed the way a nation ate. Guy learns how the trawler's radical design saw off the competition, tries his hand at the precision joinery that made that design possible, tests his own version of an Industrial Revolution life jacket by jumping into the sea, and makes rope using the original machines that wove the ropes for Nelson's HMS Victory.

In this edition Guy's project is the first piston engine ever built. The Newcomen Beam Engine was the first practical device to harness the power of steam and kick-started the Industrial Revolution by allowing coal mining to operate on an industrial scale.

Guy visits Llandudno to help get this Queen of Victorian resorts up to scratch in time for the summer season. The great British seaside holiday was a largely Victorian invention.

Guy works to get a Yorkshire saw mill up and running again, and then use it to make a replica of one of the less-celebrated inventions of the Victorian era: the first pedal-powered bicycle. Using his engineering skills, Guy helps the restoration team repair the ingenious water turbine that's needed to power the whole of Gayle Mill in Wensleydale, but which is currently leaking 43 litres of water a second.

Guy helps to overhaul a steam locomotive used on the popular Severn Valley Railway, a 16-mile stretch of track in Shropshire preserved to look just as it did in the 19th century. He joins a team of volunteers, some as young as 17, to help repair its boiler, safety valves and one of its two-tonne wheels.
