The London Underground system – popularly known as the Tube – is the oldest in the world (it opened in 1863) and the second largest in the world (only Shanghai is larger).
Today I made one of the longest tube journeys of my life by travelling from Sudbury Hill on the Piccadilly Line to Hornchurch on the District Line – a journey of 39 stops. I was visiting the organisation Wavelength – which provides free radio and television sets to needy individuals – as part of my new role as the Chair of the Digital Consumer Expect Group. It took me two hours door to door.
I could have made a longer journey on the Underground – which in fact is overground in the suburbs – since the London system has an incredible 270 stops and has around 250 miles of track.
