Underground art: London tube map designs

In Richard Long's work, Earth, the different colours of the Tube lines are separated by a black grid, which represents the Northern line. Its format is influenced by I Ching, a philosophy that underpins much of his art and which he hopes will encourage passengers to think beyond their fast-paced journeys Photograph: Courtesy the artist and Art on the Underground

Paul Noble's Troubadour Carrying a Cytiole. With a nod to the tube’s many buskers, a medieval troubadour is depicted carrying a strange instrument as he travels from court to court. The character is from a larger work exploring the fantastical, maze-like nature of the tube Photograph: PR
