London Transport Museum. This old map of the Underground train system is a more geographical representative. That approach was replaced by the schematic Tube map, designed by Harry Beck in 1931, (Wikipedia) As a schematic diagram, [the new map] does not show the geographic locations but rather the relative positions of the stations, lines, the stations' connective relations, and fare zones.

The London Transport Museum, or LT Museum based in Covent Garden, London, seeks to conserve and explain the transport heritage of Britain's capital city. The majority of the museum's exhibits originated in the collection of London Transport, but, since the creation of Transport for London (TfL) in 2000, the remit of the museum has expanded to cover all aspects of transportation in the city.
