Sheffield

Tim visits Sheffield station, the centre point of the industrial revolution, which has gone through decades of despair and been reinvented for the 21st century. Tim lends a hand to restore the Bennerley Viaduct in the Erewash valley and he also enjoys the marvels of the futuristic Estacio do Oriente in Portugal. This other worldly station was designed for Lisbon's Word Expo by the "starchitect" Santiago Calatrava.
