Andén 0 (Platform 0) is the name of the old Chamberí metro station and the Pacific Engine Shed. Since it opened in March 2008, visitors have been able to travel back in time right in the centre of Madrid. Redevelopment work on these two sites has meant that you can now visit the central ""ghost"" station of Chamberí and the Engine Shed to learn about the development and history of the metro through audiovisual presentations, activities and workshops.
