They were united by an extraordinary ambition to construct a brand new steam engine and to bring back to life the Peppercorn class A1 Pacific steam engine.

After 18 years of incredible effort and teamwork, their dream became a reality when locomotive No. 60163 Tornado, moved under its own power for the first time.

This BBC programme tells the story of the construction of a steam engine called Tornado, an amazing tale of cooperation, skill and sheer hard graft by men who defied the critics, who had said it could never be done.

Such an achievement did not go unnoticed and Tornado soon became a celebrity in its own right, taking Britain completely by storm.

Wherever it has ventured, it has attracted crowds of people. Thousands turn out to wave and cheer. Children are hoisted aloft. Men hang from bridges and stand on car roofs. Enthusiasts wait hours in muddy fields for a fleeting view.

At King's Cross, throngs blocked the platforms and when it blew a cloud of steam over the Duchess of Cornwall in York, the Prince of Wales burst out laughing.

Indeed, in its short life, Tornado, the first mainline steam engine built in Britain for almost 50 years, has been a film star, splashed across newspaper pages and filmed in action by the thousands who contributed to her £3 million cost and waited almost 20 years to see a Peppercorn class A1 Pacific running on Britain's main lines again.

It was the star of an episode of 'Top Gear', taking part in a classic challenge race from London to Edinburgh with Jeremy Clarkson on the shovel.

This beautifully shot DVD takes the story on, with new extra footage never before seen on TV. A delight, not only for fans of steam trains, but for anyone who admires a skill and determination that is steeped in the great British tradition.

DVD Extras: Speech from Prince Charles at the Royal naming ceremony. Robert Hall BBC News Interview. The first run to London. Extended interview with the team.
