Early maps As London's early transport system was operated by a variety of independent companies, there were no complete maps of the network, just for the individual companies' routes. The maps were not typically schematic and were simply the line overlaid on a regular
city map. There was no integration of the companies' services or any co-operation in advertising. In 1907,
The Evening News commissioned a pocket map, The Evening News London "Tube Map". It was the first map to show all of the lines with equal weight being given to each line, and it was the first map to use a different colour for each line. Another early combined map was published in 1908 by the
Underground Electric Railways Company of London (UERL) in conjunction with four other underground railway companies that used the "Underground" brand as part of a common advertising factor. The map showed eight routes – four operated by the UERL and one from each of the other four companies: •
UERL lines: •
Bakerloo Railway – brown •
Hampstead Railway – indigo •
Piccadilly Railway – yellow •
District Railway – green •
Other lines: •
Central London Railway – blue •
City and South London Railway – black •
Great Northern and City Railway – orange •
Metropolitan Railway – red A geographical map presented restrictions since for sufficient clarity of detail in the crowded central area of the map required the extremities of the District and Metropolitan lines to be omitted and so a full network diagram was not provided. The problem of truncation remained for nearly half a century. Although all of the western branches of the District and Piccadilly lines were included for the first time in 1933 with
Harry Beck's first proper Tube map, the portion of the
Metropolitan line beyond did not appear until 1938, and the eastern end of the
District line did not appear until the mid-1950s. The route map continued to be developed and was issued in various formats and artistic styles until 1920, when, for the first time, the geographic background detail was omitted in a map designed by
MacDonald Gill. That freed the design to enable greater flexibility in the positioning of lines and stations. The routes became more stylised but the arrangement remained, largely, geographic in nature. The 1932 edition was the last geographic map to be published before Beck's diagrammatic map was introduced.
Beck's maps The first diagrammatic map of London's rapid transit network was designed by
Harry Beck in 1931. To that end, Beck devised a simplified map with stations, straight-line segments connecting them, and the
River Thames; and lines running only vertically, horizontally, or on 45° diagonals. To make the map clearer and to emphasise connections, Beck differentiated between ordinary stations, marked with short ticks, and
interchange stations, marked with diamonds. London Underground was initially sceptical of his proposal since it was an uncommissioned spare-time project and was tentatively introduced to the public in a small pamphlet in 1933. However, it immediately became popular, and the Underground has used
topological maps to illustrate the network ever since. Despite the complexity of making the map, Beck was paid just ten
guineas () for the artwork and design of the card edition, and another five guineas () for the poster. After its initial success, he continued to design the Tube map until 1960, a single (and unpopular) 1939 edition by
Hans Schleger being the only exception. Meanwhile, as well as accommodating new lines and stations, Beck continually altered the design, such as changing the interchange symbol from a diamond to a circle and altering the line colours of the
Central line from orange to red and of the Bakerloo line from red to brown. Beck's final design, in 1960, bears a strong resemblance to the current map. Beck lived in
Finchley,
North London, and one of his maps is still preserved on the southbound platform at
Finchley Central station, on the
Northern line. In 1997, Beck's importance was posthumously recognised, and as of 2022, this statement is printed on every Tube map: "This diagram is an evolution of the original design conceived in 1931 by Harry Beck".
After Beck that shows the approximate geographic locations of the stations and lines. Note that this was before the Northern Line extension to Battersea Power Station, and the Elizabeth Line. By 1960, Beck had fallen out with the Underground's publicity officer, Harold Hutchison, who was not a designer himself but drafted his own version of the Tube map that year. It removed the smoothed corners of Beck's design and created some highly cramped areas (most notably around
Liverpool Street station), and the lines were generally less straight. However, Hutchison also introduced interchange symbols (circles for Underground-only, squares for connections with
British Rail main line services) that were black and allowed multiple lines through them, as opposed to Beck, who used one circle for each line at an interchange, coloured according to the corresponding line. In 1964, the design of the map was taken over by Paul Garbutt, who, like Beck, had produced a map in his spare time because of his dislike of the Hutchison design. Garbutt's map restored curves and bends to the diagram but retained Hutchison's black interchange circles, although squares were replaced with circles with a dot inside. Garbutt continued to produce Underground maps for at least another 20 years. Tube maps stopped bearing their designer's name in 1986, when the elements of the map then had a very strong resemblance to today's map. While the standard Tube map avoided representing most mainline services, a new variant of the map issued in 1973, the "London's Railways" map, was the first to depict Tube and above-ground mainline rail services in a diagrammatic style that closely matched Beck's designs. That version was created by Tim Demuth of the London Transport publicity office and was jointly sponsored by British Rail and London Transport. Demuth's map did not replace the standard Tube map but continued to be published as a supplementary resource, later known as the "London Connections" map.
Recent years Some alterations have been made to the map over the years. More recent designs have incorporated changes to the network, such as the
Docklands Light Railway and the
extension to the
Jubilee line. The map has also been expanded to include routes brought under
Transport for London control such as
TfL Rail and to note the Tube stops that connect with
National Rail services, links to airports and
River Services. In some cases, stations within short walking distance are now shown, often with the distance between them, such as 's distance from (an evolution of the pedestrian route between
Bank and Monument stations, which was once prominently marked on the map). Further, step-free access notations are also incorporated in the current map. In addition, the
fare zones have been added to help passengers judge the cost of a journey. One of the major changes to be made to the revision of the Tube map put out in September 2009 was the removal of the
River Thames. The river had been omitted from official maps on several previous occasions (for example, according to David Leboff and Tim Demuth's book, in 1907, 1908 and 1919), and from 1921 it was absent for several years on pocket maps designed by
MacDonald Gill. The Thames-free 2009 version was the first time that the river did not appear on the Tube map since the Stingemore pocket map of 1926. The latest removal resulted in widespread international media attention, and general disapproval from most Londoners as well as from the then
Mayor of London,
Boris Johnson. Based on the reaction, the following edition of the diagram in December 2009 reinstated both the river and fare zones. In more recent years, TfL has expanded its rail services, notably with the expansion of the
London Overground network, which has taken over a number of National Rail lines and brought them into the TfL network, each of them being converted lines being added to the Tube map. Further additions have been made such as the London Cable Car and the boundaries of fare zones. Some commentators have suggested that Beck's design should be replaced with a new design that can incorporate the new lines more comfortably.
Pocket map covers Since 2004,
Art on the Underground has commissioned various British and international artists to create a cover for the pocket map. These free maps are one of the largest public art commissions in the UK, with millions of copies printed. Over 40 different designs have been produced, from a wide variety of British and international artists such as
Rachel Whiteread,
Yayoi Kusama,
Tracey Emin and
Daniel Buren. ==Technical aspects==
