map update

The Tube map (sometimes called the London Underground map) is a schematic transport map of the lines, stations and services of the London Underground, known colloquially as "the Tube", hence the map's name. The first schematic Tube map was designed by Harry Beck in 1931. Since then, it has been expanded to include more of London's public transport systems, including the Docklands Light Railway, London Overground, the Elizabeth line, Tramlink, the London Cable Car and Thameslink.
As a schematic diagram, it shows not the geographic locations but the relative positions of the stations, lines, the stations' connective relations and fare zones. The basic design concepts have been widely adopted for other such maps around the world and for maps of other sorts of transport networks and even conceptual schematics.
A regularly updated version of the map is available from the official Transport for London website. In 2006, the Tube map was voted one of Britain's top 10 design icons which included Concorde, Mini, Supermarine Spitfire, K2 telephone box, World Wide Web and the AEC Routemaster bus. Since 2004, Art on the Underground has been commissioning artists to create covers for the pocket Tube map.
