Award-winning – some award, she won the big one, the Guide of the Year Award – guide Fiona does a weekly tour for London Walks that explores the Tube. Called The Lure of the Underground, it explores the Tube above and below ground. Drawn from Fiona’s tour of the Underground, this fascinating Podcast “takes us down in there”, sheds a great deal of light on the Tube. Not least the big question: how in the world did they do it, how did the world’s first underground transport system come into existence? The Tube is something we all take for granted. I guarantee you, you’ll never do so again after listening to what Fiona’s got to say here.
