Description of works

The works consisted of the renovation of the existing trackbed and the quadrupling of the tracks on a 2.7 km section. In addition, a 4.7 km tunnel was built and two new stations (Fuente de la Mora and Valdebebas) were constructed, while two other existing stations (Hortaleza and Barajas) were refurbished. The construction of a cut-and-cover tunnel was also completed.

Underground section

The underground section of the railway access to Madrid-Barajas Airport is 4.7 km long. Two solutions have been used for its construction: 2.9 km of underground tunnel and 1.8 km of cut-and-cover tunnel between screens.

The tunnel in mine was built using the so-called Belgian method, or the traditional Madrid method, which consists of excavating its section in 2.5 m long advances. The excavation of the tunnel is carried out by manual procedures, in phases of reduced section, so that as the tunnel is excavated, the shoring is carried out.
