Editing Tube map (section)

===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>
* Tramlink, shown in 2016 as London Trams, was included on the map from June 2016.
* The [[Elizabeth line]] was added to the map in May 2022.<ref>{{Cite web |date=2022-05-19 |title=The Elizabeth line unveiled on latest London Tube map |url=https://tfl.gov.uk/info-for/media/press-releases/2022/may/the-elizabeth-line-unveiled-on-latest-london-tube-map |access-date=2023-02-01 |publisher=Transport for London|archive-date=1 February 2023 |archive-url=https://web.archive.org/web/20230201001403/https://tfl.gov.uk/info-for/media/press-releases/2022/may/the-elizabeth-line-unveiled-on-latest-london-tube-map |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.
