En tren por el nuevo continente: Estados Unidos

Michael braves the awesome power and drenching spray of Niagara Falls on the Maid of the Mist to share what artists, daredevils and millions of tourists have billed as one of the most spectacular experiences on the planet. Reaching Buffalo, he lunches on the city's famous Buffalo wings and discovers it was once the centre of the world's grain trade. Touring Silo City, Michael learns about the invention which propelled the port of Buffalo into its dominant position - the grain elevator - and how the railroads sealed the deal. Awe-inspiring engineering is revealed at the 12-acre Colonel Ward water-pumping station, the largest construction ever built on the Great Lakes, and capable of delivering 30 million gallons of water per day to the city of Buffalo.
