The Community of Madrid is to begin work next August on the extension of Metro line 11 as it passes through Atocha. This infrastructure will connect the north and south of the capital, distributing the passengers who currently travel on line 6 more evenly.

Likewise, the Regional Minister for Housing, Transport and Infrastructure, Jorge Rodrigo, pointed out that the construction of this new installation "entails the dismantling of the monument in homage to the victims of 11M located in the lobby of Atocha station".

For this reason, Rodrigo has held a meeting at the Regional Ministry with the victims' associations based in Madrid to explain the characteristics of this work, assuring them that the regional government "will create a working group to inform them on a regular basis of the status of these actions and incorporate their ideas and contributions to the final project".

Given the connection of Atocha station with Metro line 1, this point of the underground will benefit the most from this extension. Once the works have been completed, this infrastructure will become one of the busiest of the 249 in the Metro network, together with those of Sol, Moncloa, Nuevos Ministerios and Príncipe Pío.
