A Tube map is a simplified diagram representing the underground train system in London, known as the London Underground. It shows the various train lines, stations, and connections in a clear and easy-to-read format, allowing passengers to navigate the network efficiently. The map uses different colors for each line and is not drawn to scale, focusing instead on clarity. The original Tube map was designed by Harry Beck in 1931. His innovative approach transformed how transit maps are created, emphasizing simplicity over geographical accuracy. Today, the Tube map is an iconic symbol of London and is widely recognized around the world.
