Madrid and Buenos Aires subway lines mirror each other in design and goals

Madrid's Line 11 and Buenos Aires' Line F subway projects share a core objective: optimizing passenger travel times through innovative transversal routes. Miguel Núñez Fernández, Director General of Collective Transport Infrastructure for the Community of Madrid, highlighted this parallel during a conference in Buenos Aires, noting that both lines aim to break away from purely radial network designs.

Núñez Fernández explained that traditional radial networks, where lines converge centrally and extend to peripheries, often force passengers into lengthy and inefficient journeys. "These radial networks sometimes need to be broken by a transversal layout that makes them more efficient," he stated. Both the Madrid and Buenos Aires projects incorporate north-south axes designed to cut across existing lines, significantly reducing travel distances and improving overall network efficiency.

A secondary, yet equally crucial, goal for both lines is to alleviate congestion on the busiest existing routes. In Madrid, Line 11 is intended to ease the burden on Line 6, the city's primary circular line. Similarly, Buenos Aires' Line F will serve to decompress Line C, which currently handles high passenger volumes between Constitución and Retiro.

Further commonalities include the integration of these new lines with the existing subway systems and their connections to major transport hubs. Madrid's Line 11 will link to Atocha station and Barajas Airport, while Buenos Aires' Line F will connect Constitución, a key railway terminal, with the Palermo area and the San Martín railway line. Núñez Fernández stressed that this focus on connectivity, rather than simply adding kilometers of track, should guide future urban transit expansion.
