With its famous hotel, St Pancras is now the London terminus of the Eurostar, with a high speed rail link to the Kent coast and the Channel Tunnel. But it was not always so. Once nearly redundant and threatened with demolition, the station was the London terminus of the Midland Railway, and could proclaim at its opening the largest single span roof in the world. Over GBP800 million saw St Pancras restored and rebuilt for the modern day. Described now as the 'world's most wonderful railway station', St Pancras is a paragon of Gothic architecture. The St Pancras Renaissance London Hotel utilised large parts of the Midland Grand Hotel and opened in 2011, exactly 138 years after the original was opened. John Christopher tells the story of the rise, decline and rise again of St Pancras as London's international station.
