Editing London Underground (section)

===Disused and abandoned stations===
{{main|List of former and unopened London Underground stations}}
In the years since the first parts of the London Underground opened, many stations and routes have been closed. Some stations were closed because of low passenger numbers rendering them uneconomical; some became redundant after lines were re-routed or replacements were constructed; and others are no longer served by the Underground but remain open to [[National Rail]] main line services. In some cases, such as [[Aldwych tube station|Aldwych]] and [[Ongar railway station|Ongar]], the buildings remain and are used for other purposes. In others, such as [[British Museum tube station|British Museum]], all evidence of the station has been lost through demolition.

[[London Transport Museum]] runs guided tours of several disused stations including [[Down Street tube station|Down Street]] and Aldwych through its "Hidden London" programme. The tours look at the history of the network and feature historical details drawn from the museum's own archives and collections.<ref>{{Cite web |title=New Tickets Released for Hidden London tours |url=https://www.ltmuseum.co.uk/news/new-tickets-released-hidden-london-tours |access-date=15 February 2023 |website=London Transport Museum |date=25 January 2023 |language=en |archive-date=5 November 2023 |archive-url=https://web.archive.org/web/20231105190956/https://www.ltmuseum.co.uk/news/new-tickets-released-hidden-london-tours |url-status=live }}</ref>
