3,375 m of excavation was carried out with a 9.44-m diameter EPB tunnel boring machine, and 1,925 m were excavated by conventional means using the Belgian method.
ACCIONA's experience in the construction of suburban lines is backed by a long and successful history of project execution in major Spanish and foreign cities, where it has carried out different large-scale projects in recent years.
Two stations were built, one of which was the new Nuevos Ministerios interchange.
