Ineco has begun technical studies to modify the alignment and infrastructure of the line 5 track of the Madrid Metro. Specifically, the works –which were tendered within the Framework Agreement signed by both companies– refer to the section between the stations of Eugenia de Montijo and Aluche. The studies have the objective of increasing the speed in this section. The modification requires actions on foundations and structures, land treatment, soil-structure interaction, a study on filtration, alignment and the superstructure of the track, mapping, installations and environmental integration.
