Madrid Metro Line 6 to close for automated train testing

Madrid Metro's Line 6, the network's most heavily used line, will undergo service interruptions on the weekends of October 17–18 and October 24–25. The closures will affect the section between Cuatro Caminos and Lucero to facilitate safety testing for new driverless, automated trains.

The service disruption will impact eight stations: Guzmán el Bueno, Vicente Aleixandre, Ciudad Universitaria, Moncloa, Argüelles, Príncipe Pío, Puerta del Ángel, and Alto de Extremadura. During these periods, Cuatro Caminos and Lucero will remain operational as terminal stations.

To assist commuters, Metro will provide a free special bus service to cover the affected route. Passengers can also use connections with Lines 1, 2, 3, 4, 7, and 10, as well as the Ramal, to navigate the network. Regional authorities noted that the list of affected stations for the second weekend may change depending on the results of the initial tests.
