Some closed station buildings are still standing, converted for other uses or abandoned, while others have been demolished and their sites redeveloped.
The interiors and platforms of a few closed stations are among parts of the London Underground available for filming purposes, such as those at Aldwych.
The tours look at the history of the network and feature historical details drawn from the museum's own archives and collections.
Many are permanently closed, but some continue to be served by National Rail main line train operators.
Subsequent changes of plans or shortages of funds led to these stations being cancelled before they opened, and, in most cases, before any construction work was carried out.
