The Line 1 of Madrid's Metro system will undergo a significant change by becoming the first line with a double terminus. Instead of ending solely at Pinar de Chamartín, trains will split at Plaza de Castilla, with some heading toward Pinar de Chamartín and others continuing northward to new developments in Madrid Nuevo Norte. This decision follows complaints from residents of Pinar de Chamartín who opposed plans to connect the segment between Plaza de Castilla and Pinar de Chamartín to Line 4. The new design includes three new stations: Centro de Negocios, Fuencarral Sur, and Fuencarral Norte, with the latter serving as the northern terminus. The implementation of this change is expected to take years and is tied to the development of Madrid Nuevo Norte.
