Editing Tube map (section)

==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.

The font for the map, including station names, is [[Johnston (typeface)|Johnston]], which uses perfect circles for the letter 'O'. That is historic and the generic font for all TfL uses from station facades to bus destination blinds.<ref>{{cite web |url=http://www.tfl.gov.uk/tfl/corporate/media/fonts/ |title=Font requests &#124; Transport for London |publisher=Tfl.gov.uk |access-date=18 April 2013 |archive-date=13 April 2013 |archive-url=https://web.archive.org/web/20130413030020/http://www.tfl.gov.uk/tfl/corporate/media/fonts/ |url-status=dead }}</ref>

===Line colours===
The table below shows the changing use of colours since Beck's first map. The current colours are taken from Transport for London's colour standards guide,<ref name="ColourStandardNov24">{{cite web |author1=Transport for London |author1-link=Transport for London |title=Colour standard |url=https://content.tfl.gov.uk/tfl-colour-standard.pdf |website=Transport for London |access-date=18 March 2025 |archive-url=https://web.archive.org/web/20250311200745/https://content.tfl.gov.uk/tfl-colour-standard.pdf |archive-date=11 March 2025 |version=Issue 9 |date=November 2024 |url-status=live}}</ref> which defines the precise colours from the [[Pantone]] palette and also a colour naming scheme that is particular to TfL. Earlier maps were limited by the number of colours available that could be clearly distinguished in print. Improvements in [[colour printing]] technology have reduced that problem and the map has coped with the identification of new lines without great difficulty.

Pecked lines have at various times indicated construction, limited service, or sections closed for renovation.

===Station marks===
From the start, interchange stations were given a special mark to indicate their importance, but its shape has changed over the years. In addition, since 1960, marks were used to identify stations that offered connections with [[British Rail]] (now [[National Rail]]). The following shapes have been used:
* Circle (one for each line or station, where convenient)&nbsp;– standard default mark
* Circle (one for each station)&nbsp;– 1938 experimental map
* Diamond (one for each line)&nbsp;– early 1930s
* Square&nbsp;– interchange with British Railways, 1960–1964
* Circle with a dot inside&nbsp;– interchange with British Rail, 1964–1970

Since 1970 the map has used a reversed (red on white) British Rail "double arrow" beside the station name to indicate main line interchanges. Where the main line station has a different name from the Underground station that it connects with, since 1977 this has been shown in a box. The distance between the Tube station and the main line station is now shown.

Contemporary maps have marked stations offering step-free access with a blue circle containing a wheelchair symbol in white.

Stations with links to airports ([[Heathrow Terminals 2 & 3 tube station|Heathrow Terminals 2 & 3]], [[Heathrow Terminal 4 tube station|Terminal 4]], and [[Heathrow Terminal 5 station|Terminal 5]] for [[Heathrow Airport]] and the [[London City Airport DLR station|DLR station at City Airport]]) are shown with a black aeroplane symbol.

Since 2000, stations with a nearby interchange to river bus piers on the Thames have been marked with a small boat symbol to promote [[London River Services]].

When [[Eurostar]] services used {{Stnlnk|Waterloo International}}, the Eurostar logo was shown next to [[London Waterloo station|Waterloo station]]. In November 2007, the terminus was transferred to [[St Pancras railway station|St Pancras International]].

===Lines or services===
The Tube map aims to make the complicated network of services easy to understand, but it is not possible to have complete information about the services that operate on each line.

Limited-service routes have sometimes been identified with hatched lines, with some complications added to the map to show where peak-only services ran through to branches such as that to [[Chesham tube station|Chesham]] on the Metropolitan line. The number of routes with a limited service has declined in recent years, as patronage has recovered from its early-1980s low. As there are now fewer restrictions to show, most of the remaining ones are now indicated in the accompanying text, rather than by special line markings.

===Official versions===
The Tube map exists to help passengers navigate the London rapid transit network, and whether it should play a wider role in helping people navigate London itself has been questioned. The question has been raised as to whether mainline railways should be shown on the map, particularly those in [[Inner London]]. The Underground has largely resisted adding additional services to the standard Tube map and instead produces separate maps with different information, including:
* [http://content.tfl.gov.uk/standard-tube-map.pdf Standard Tube map]: Shows all Underground, London Overground, DLR, [[Elizabeth line]], Tramlink and Thameslink routes and stations, and fare zones.
* [http://content.tfl.gov.uk/bw-large-print-map.pdf Large print Tube map] {{Webarchive|url=https://web.archive.org/web/20161130173136/http://content.tfl.gov.uk/bw-large-print-map.pdf |date=30 November 2016 }}: As above but with larger print.
* [http://content.tfl.gov.uk/walking-tube-map.pdf Walking distance map]: Shows walking times between stations in the central London area.

* London Connections map: Produced by the [[Association of Train Operating Companies]] (ATOC), this provided the same information as TfL's Travelcard Zones map but extended further beyond [[List of stations in London fare zones 7–9, G and W|fare zones 7–9]]. National Rail lines were emphasised by thicker lines and coloured according to their [[train operating company]] (TOC). This map was replaced by the Oyster Rail Services map.<ref>{{cite web |url=http://www.nationalrail.co.uk/passenger_services/maps/ |title=National Rail Enquiries – Maps |publisher=Nationalrail.co.uk |access-date=9 January 2013 |archive-date=6 January 2013 |archive-url=https://web.archive.org/web/20130106054927/http://nationalrail.co.uk/passenger_services/maps/ |url-status=live }}</ref>

Maps are produced in different sizes, the most common being Quad Royal (40 × 50&nbsp;inches<ref>{{cite web |url=http://www.ltmcollection.org/posters/results/results.html?IXsearchformat=Quad%20royal |title=Search Results: Quad royal – Poster and poster artwork collection, London Transport Museum |work=ltmcollection.org |access-date=10 October 2009 |archive-date=11 September 2012 |archive-url=https://web.archive.org/web/20120911084826/http://www.ltmcollection.org/posters/results/results.html?IXsearchformat=Quad%20royal |url-status=dead }}</ref>) poster size and Journey Planner pocket size. The maps showing all the National Rail routes provide useful additional information at the expense of considerably increased complexity, as they contain almost 700 stations.

===Non-London Underground lines on standard map===
Some non-Underground lines have appeared on the standard tube map:
* On the early maps that used a geographic background, mainline railways were shown as part of the background detail.
* Prior to its transfer to the London Underground in 1994, the [[Waterloo & City line]] was operated by [[British Rail]] and its mainline predecessors but has appeared on most Tube maps since the mid-1930s.
* For a short period in the late 1930s to 1940, the section of the [[West London line]] linking [[Willesden Junction station|Willesden Junction]] to the Metropolitan line's [[Middle Circle]] route at [[Uxbridge Road tube station|Uxbridge Road]] was shown as a service operated by the [[Great Western Railway]] and the [[London, Midland and Scottish Railway]]. The service was removed when the line closed to passengers in 1940.<ref name="1939 map"/> This section of the line is today shown as part of the [[London Overground]].
* The [[North London line]] was added to the map in 1977.<ref name="1977 map">[http://www.clarksbury.com/cdl/maps/tube77.jpg 1977 map] {{Webarchive|url=https://web.archive.org/web/20070709205905/http://www.clarksbury.com/cdl/maps/tube77.jpg |date=9 July 2007 }} from {{cite web |title=The London Tube Map Archive |url=http://www.clarksbury.com/cdl/maps.html |access-date=7 February 2009 |archive-date=11 August 2007 |archive-url=https://web.archive.org/web/20070811163253/http://www.clarksbury.com/cdl/maps.html |url-status=live }}</ref> Although run by [[British Rail]] and later by [[Silverlink]], it was shown in British Rail/National Rail colours, but its appearance was intermittent and was omitted from some map editions over the years. In November 2007, the line was taken over by London Overground and changed to an orange double stripe. The semi-orbital route originally ran from [[Richmond station (London)|Richmond]] to [[Broad Street railway station (England)|Broad Street]] and later Richmond to [[North Woolwich railway station|North Woolwich]]. The line runs now from Richmond to [[Stratford station|Stratford]].
* The [[West London line]], [[Watford DC line]] and [[Gospel Oak to Barking line]] (former British Rail/Silverlink lines) were all added to the standard map in 2007, when they were taken over by London Overground, and all are shown as an orange double stripe.
* The [[Northern City Line]] appeared on the original 1908 map as the Great Northern and City Railway. It later appeared as the Great Northern and City section of the Metropolitan Railway and then, from the late 1930s as part of the Northern line. The service was transferred to [[British Rail]] in 1975 and continued to appear until recently.
* [[Thameslink]] reopened in 1988 after it had been closed for many years. It offers some relief to the Northern line, as it connects King's Cross St Pancras to London Bridge. Only the central sections between Kentish Town and London Bridge/Elephant & Castle were shown. Its appearance on Tube maps had been intermittent since it had been omitted from some map editions over the years, before it was re-added to the official tube map in December 2020.
* The [[Docklands Light Railway]], the automatic light rail system in the [[London Docklands]] area.
* The [[London Cable Car]], linking [[Greenwich Peninsula]] and [[Royal Docks]] across the Thames, was added in December 2011.
* The first section of the [[Crossrail]] franchise, [[TfL Rail]], was added in May 2015.
* Also in May 2015, the [[Chingford branch line|Chingford line]], [[Lea Valley lines|Enfield & Cheshunt line]], and [[Romford–Upminster line]] were added to the London Overground network on the tube map.<ref name='overground2015'>{{cite news|last=Gwyn|first=Topham|title=Clean, reliable and integrated: all change for neglected rail services in London|newspaper=The Guardian|date=2015-05-29|access-date=2019-06-25|url=https://www.theguardian.com/uk-news/2015/may/29/neglected-rail-services-london-tfl-overground|archive-date=23 August 2017|archive-url=https://web.archive.org/web/20170823022954/https://www.theguardian.com/uk-news/2015/may/29/neglected-rail-services-london-tfl-overground|url-status=live}}</ref>

When Transport for London expanded its [[London Overground]] service to include the [[East London line]] in 2010, the East London line, extended to Croydon, changed from a solid orange line to a double orange stripe. According to 2007 proposals, the addition of the [[South London line]] to London Overground was supposed to cause the southern loop to be added to future Tube maps in late 2010,<ref name="2010 tube map">{{cite web |url=http://www.tfl.gov.uk/resources/corporate/media/pressimages/rez-high/h-tube-map-2010.jpg |title=The Tube in 2010 |author=Transport for London |year=2006 |access-date=3 November 2007 |archive-date=15 July 2011 |archive-url=http://webarchive.nationalarchives.gov.uk/20110715111749/http://www.tfl.gov.uk/resources/corporate/media/pressimages/rez-high/h-tube-map-2010.jpg |url-status=dead }} (map illustrating future development phases as proposed by TfL in 2006, subject to change)</ref> and, as of May 2013, it is up and running.

Transport for London formerly published several bus maps that depicted the approximate paths of tube routes relative to major streets and [[London buses|London bus routes]].<ref>{{cite web |title=Central London Bus Map |publisher=TfL |url=http://www.tfl.gov.uk/assets/downloads/Central-London-Day-Bus-Map.pdf |access-date=7 February 2009 |archive-date=17 January 2009 |archive-url=https://web.archive.org/web/20090117151552/http://tfl.gov.uk/assets/downloads/Central-London-Day-Bus-Map.pdf |url-status=dead }}</ref> The maps also show locations of certain cultural attractions and geographic landmarks.

Internet mapping services such as [[Google Maps]] offer a "Transit Layer" showing actual routes superimposed on the standard street map. A map shows Underground, London Overground, Elizabeth line, DLR lines and National Rail stations within Zone 1–2.<ref>{{cite web |url=http://www.innerlondontubemap.blogspot.com/ |title=Inner London Tube Map |work=innerlondontubemap.blogspot.com |access-date=1 July 2013 |archive-date=29 October 2013 |archive-url=https://web.archive.org/web/20131029204228/http://www.innerlondontubemap.blogspot.com/ |url-status=live }}</ref>
