Inside the Tube: Going Underground S01E04 - The First Modern Tube Line

The Piccadilly Line is famed for its glamorous stops, which include Knightsbridge and the West End. Rob Bell discovers how the Piccadilly Line played an important part in saving the Tube from bankruptcy, as well as how it changed the face of public transport. He visits an abandoned station beneath Piccadilly Circus, where he discovers just what was needed to modernize this much-loved stop in the 1920s, when a surge in motorized buses drew passengers away.
