All the great steam locomotives of yesteryear are here, the 1815 'Steam Elephant' and Stephenson's 'Rocket'  through to the precious preserved locos. The programme includes 'City of Truro' (the first steam engine to exceed 100 mph), 'Flying Scotsman' (the world's most famous steam locomotive), 'Mallard' (world speed record holder for a steam locomotive) and 'Evening Star' (the last ever steam engine built for British Railways).
