About
Línea 11 (L11) refers to Line 11 of the Metro de Madrid. It is newsworthy due to its ongoing expansion project, which aims to extend the line to areas including Valdebebas and Cuatro Vientos, and eventually connect to the central part of the city. The activation of the tunnel boring machine named 'Mayrit' marks a significant step in this expansion. Mayrit is currently drilling the connection between Comillas and Conde de Casal, a process expected to take 13-14 months. The machine is progressing at a rate of approximately 15 meters per day, aiming to advance 500 meters each month. The expansion of Línea 11 is relevant as it will improve transportation infrastructure and connectivity within Madrid, potentially impacting commuting patterns and accessibility to different parts of the city.
