Early maps

What is now a single network of lines controlled by a single organisation began as a collection of independent underground railway companies that constructed lines in the 19th and early 20th centuries. These companies published route maps of their own services but did not, generally, co-operate in advertising their services collectively. Early maps were based on standard geographic city map

After Beck

By 1960, Beck had fallen out with the Underground's publicity officer, Harold Hutchinson. Hutchinson, though not a designer himself, 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
Liverpool Street station
Liverpool Street railway station, also known as London Liverpool Street or simply Liverpool Street, is both a central London railway terminus and a connected London Underground station in the north-eastern corner of the City of London, England...

); in addition, lines were generally less straight. However, Hutchinson also introduced interchange symbols (circles for Underground-only, squares for connections with British Rail
British Rail
British Railways , which from 1965 traded as British Rail, was the operator of most of the rail transport in Great Britain between 1948 and 1997.

) 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 due to his dislike of the Hutchinson design. Garbutt's map restored curves and bends to the diagram, but retained Hutchinson's black interchange circles (the squares however were replaced with circles with a dot inside). Garbutt continued to produce Underground maps for at least another twenty years — Tube maps stopped bearing the designer's name in 1986, by which time the elements of the map bore a very strong resemblance to today's map. Today, the Tube map bears the legend, "This diagram is an evolution of the original design conceived in 1931 by Harry Beck" in the lower right-hand corner.

While the standard Tube map mostly avoided representing mainline rail services, a new variant of the map issued in 1973, the 'London's Railways' map, was the first to depict Tube and surface rail services in a diagrammatic style closely matched to Beck's designs. This 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.

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

 routes, and Tube stops with connections to National Rail services, rail links to airports, and river boats. Stations that can be walked between are now shown, often with the distance between them (this is 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 map.

In addition, since 2002 the fare zones have been added, to better help passengers judge the cost of a journey. Nevertheless the map remains true to Beck's original scheme, and many other transport systems use schematic maps to represent their services, likely inspired by Beck.

Despite there having been many versions over the years, somehow the perception of many users is that the current map actually is, more or less, Beck's original version from the 1930s — a testament to the effectiveness of his design. Beck did actually draw versions with other formats, 22½ degrees rather than 45 (the Paris Métro

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

. Although historically the river was not present on several official maps (for example, according to David Leboff and Tim Demuth's book; in 1907, 1908, and 1919), 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 has not appeared on the Tube map since the Stringemore pocket map of 1926. This latest removal resulted in widespread international media attention, and general disapproval from most Londoners as well as from mayor

Technical aspects

The designers of the map have tackled a variety of problems in showing information as clearly as possible and have sometimes adopted different solutions.

After Beck

By 1960, Beck had fallen out with the Underground's publicity officer, Harold Hutchinson. Hutchinson, though not a designer himself, 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
Liverpool Street station

); in addition, lines were generally less straight. However, Hutchinson also introduced interchange symbols (circles for Underground-only, squares for connections with British Rail
British Rail

) 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 due to his dislike of the Hutchinson design. Garbutt's map restored curves and bends to the diagram, but retained Hutchinson's black interchange circles (the squares however were replaced with circles with a dot inside). Garbutt continued to produce Underground maps for at least another twenty years — Tube maps stopped bearing the designer's name in 1986, by which time the elements of the map bore a very strong resemblance to today's map. Today, the Tube map bears the legend, "This diagram is an evolution of the original design conceived in 1931 by Harry Beck" in the lower right-hand corner.

While the standard Tube map mostly avoided representing mainline rail services, a new variant of the map issued in 1973, the 'London's Railways' map, was the first to depict Tube and surface rail services in a diagrammatic style closely matched to Beck's designs. This 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.

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

 routes, and Tube stops with connections to National Rail services, rail links to airports, and river boats. Stations that can be walked between are now shown, often with the distance between them (this is 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 map.

In addition, since 2002 the fare zones have been added, to better help passengers judge the cost of a journey. Nevertheless the map remains true to Beck's original scheme, and many other transport systems use schematic maps to represent their services, likely inspired by Beck.

Despite there having been many versions over the years, somehow the perception of many users is that the current map actually is, more or less, Beck's original version from the 1930s — a testament to the effectiveness of his design. Beck did actually draw versions with other formats, 22½ degrees rather than 45 (the Paris Métro

The Thames-free 2009 version was the first time that the river has not appeared on the Tube map since the Stringemore pocket map of 1926.

Early maps

What is now a single network of lines controlled by a single organisation began as a collection of independent underground railway companies that constructed lines in the 19th and early 20th centuries. These companies published route maps of their own services but did not, generally, co-operate in advertising their services collectively. Early maps were based on standard geographic city map

Being geographically-based presented restrictions in this early map; to enable sufficient clarity of detail in the crowded central area of the map, the extremities of the District and Metropolitan lines were omitted, so a full network diagram was not provided.

's first map, the portion of the Metropolitan line beyond Rickmansworth did not appear until 1938 and the eastern end of the District line did not appear on the map 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. This 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 the diagrammatic map was introduced.

s). London Underground was initially sceptical of his proposal — it was an uncommissioned spare-time project, and it was tentatively introduced to the public in a small pamphlet in 1933. It immediately became popular, and the Underground has used topological maps to illustrate the network ever since.

Station marks

An important symbol that Beck introduced was the 'tick' mark to indicate stations. This allowed stations to be placed closer together while preserving clarity, because the tick was only on the side of the line nearer the station name (ideally centrally placed, though the arrangement of lines did not always allow this).

From the start, interchange stations were given a special mark to indicate their importance, though its shape has changed over the years. In addition, from 1960, marks were used to identify stations that offered connections with British Railways (now National Rail

). The following shapes have been used:
  • Circle (one for each line or station, where convenient) - standard default mark
  • Circle (one for each station) - 1938 experimental map
  • Diamond (one for each line) - early 1930s
  • Square - interchange with British Railways, 1960–1964
  • Circle with a dot inside - interchange with British Rail

Official versions of the Tube map

The Tube map exists to help passengers navigate the London rapid transit network and it has been questioned whether it should play a wider role in helping people navigate London itself. The question has been raised as to whether mainline railways should be shown on the map, in particular those in inner-London. The Underground has largely resisted adding additional services to the standard Tube map, instead producing separate maps with different information, including:
  • Standard Tube map: Shows all Underground, DLR and Overground lines and stations, and zone boundaries.
  • Central London map: A cropped and enlarged version of the standard map showing only the central London

Spin-offs and imitations

The success of the tube map as a piece of information design has led to many imitations of its format. In 2002 Transport for London launched a series of London Buses

 "spider diagrams" to display at bus stops around the city, conveying bus route information in a schematic style similar to Beck's design, with straight lines and 45° angles depicting geographically distorted bus routes, coloured lines and numbers to differentiate services, and graphical markers to show bus stops. Tube and rail lines are not included, but interchanges are denoted with appropriate symbols by bus stop names, such as the Tube roundel. Unlike the traditional Tube map, the bus maps display services appropriate to specific transport hubs rather than a full network. Each map also contains a central rectangle of a simple, geographically accurate street map to display the positions of bus stops; outside this rectangle, the only geographic feature to appear on the bus maps is the River Thames. These maps are also available for electronic download, with map collections ordered by London borough. The bus maps were designed for TfL by the cartographic design company T-Kartor group.

In June 2011, British Designer Mark Noad unveiled his vision for a more 'geographically accurate' London Underground map. The map is an attempt to see if it is possible to create a geographically-accurate representation of the underground system while still retaining some of the clarity of Beck's original diagram. It uses similar principles, fixed line angles – in this case 30 and 60 degrees instead of 45 – and shortens the extremities of the lines to make it more compact.

Cultural references

The design has become so widely known that it is now instantly recognisable as representing London. It has been featured on T-shirts, postcards, and other memorabilia. In 2006, the design came second in a televised search for the most well known British design icon. It is widely cited by academics and designers as a 'design classic' and it is due to these cultural associations that London Underground does not usually permit the design to be used or altered for any other purpose. This has only been officially sanctioned on a few occasions:
