El Adolfo Suárez Madrid-Barajas Airport will take a qualitative leap in its connectivity by fully integrating into the Spanish high-speed network in 2026.
This ambitious initiative, which has an investment of 63 million euros from the Ministry through Adif, seeks to promote a more sustainable transport model and strengthen the intermodality The country's main airport terminal, which already has connections to commuter trains and buses, will significantly optimize travel times and increase comfort for medium- and long-distance passengers, boosting the efficiency and competitiveness of air and rail travel.
The project includes the construction of a new 3,5-kilometer standard gauge line that will connect the northern terminus of the station Madrid-Chamartín-Clara Campoamor with the airport access tunnel. In addition, a section of the existing commuter line to Terminal 4, which was already designed to accommodate high-speed trains along part of its route, will be used.
The highly complex works, as the commuter line remains operational, include adapting the track inside the airport's north tunnel to fully implement the triple wire system, as well as deploying advanced signaling systems. Currently, work is focused on constructing the subballast layer, laying foundations, laying the track, and installing the first switches.
During his visit, Minister Puente and Commissioner Tzitzikostas toured the airport facilities, listed as the third international hub of the European Union and the main gateway to Spain, with 66 million passengers registered in 2024. They had the opportunity to see the Airport Management Center up close, from where all air and ground operations are monitored and controlled in real time.
In addition, Aena's plans for the improving the capacity of the Spanish airport network and the strategies underway to achieve carbon neutrality by 2026 and zero emissions by 2030, within the framework of the Aena Climate Action Plan, which has an investment of 750 million euros.
The construction of the standard gauge access to Terminal 4 of Adolfo Suárez Madrid-Barajas Airport has been funded by European funding through the Recovery, Transformation and Resilience Plan, which underlines the strategic importance of this project for the cohesion and development of the European Union.
