Madrid Metro to invest €400 million in Line 1 expansion

The Madrid Metro has confirmed the final design for the extension of Line 1, part of the Madrid Nuevo Norte urban development project. The expansion involves a €400 million investment and will introduce a historic first for the network: a line with two terminal stations, or a “double head.”

The project will extend Line 1 via a branch starting from the Chamartín station, adding three new stations: Centro de Negocios, Fuencarral Sur, and Fuencarral Norte. Fuencarral Norte will serve as one of the two starting points for the line, alongside Pinar de Chamartín. This configuration means passengers traveling north must distinguish between trains destined for Pinar de Chamartín and those for Fuencarral Norte.

The expansion is designed to support the Madrid Nuevo Norte redevelopment, which includes the creation of a new park and 10,500 homes. Authorities rejected an alternative plan that would have merged Line 4 into Line 1, as it would have required southern-bound passengers to transfer after only two stops.
