The layout of the commuter tracks is depressed at the entrance of the station and returns to ascend to the initial level at the exit of it, while the High Speed line would have a substantially horizontal layout.
Railway connection of the Mediterranean Corridor, Madrid-Barcelona-French high-speed line. The section considered has a length of 65.2 km in double track for circulation at 220 km / hour. The works include, among other actions, the extension of sub-ballast, expansion of the platform in the station of L'Hospitalet del Infant, expansion of the platforms in the mouths of the Los Rojales tunnel, construction of two dual-width changers and one provisional one, placement of acoustic screens, etc.
Railway arterial network of Valladolid. Variant East. Platform. It has a total length of 17.5 km, with 2 branches in the initial section and two provisional links with the current route at the beginning and end of the section. A variant in Iberian gauge will be developed, mainly for the transport of merchandise, on which will be located a New Railway Complex, which will have access in international gauge. The layout in plan with design speed of 160 km / h, runs on the surface along its entire length except in 2 km in which the ground runs underground, being mostly false tunnel. The type section of the platform is suitable for a double track of Iberian gauge with an entree of 4.0 m, although in a zone of 6 km the platform is extended to accommodate a third track in UIC gauge, to be installed in the future. As for the structures, the variant has 1 viaduct, 5 underpasses, 8 overpasses and a pedestrian walkway. The most unique structure is the viaduct of "Los Tramposos", on the N-601 road, with a total length of 1,130.5 meters.
Track assembly of the High Velocity Line between León – Asturias. Track: La Robla-Campomanes. Phase I. The contract includes the assembly of 41,4 km of track, comprising tunnels, viaducts and stretches in the cut or embankment. The main actions to be carried out include the replacement of polyvalent sleeper by mixed-width sleeper in a section of 3.9 km, change of width 1668 mm to width 1435 mm in a length of 2.7 km and assembly of track in mixed width in a total length of 52.1 km.
Track renewal on the Ciudad Real-Badajoz line. Section: Cabeza del Buey-Castuera. The superstructure will be renewed and there will be a rationalization of the stations, with the renovation of several railway tracks and the withdrawal of others currently in disuse. Improvements will be made to drainage works and security and communication facilities, as well as to ensure compliance with clearance regulations.
> Metro and Metropolitan Infrastructures
Riyadh Metro. Lines 4, 5 and 6 (Saudi Arabia). The project includes the design and construction of lines 4 (yellow), 5 (green) and 6 (purple), which will have 25 stations for which 64.6 kilometers of subway tracks will be required, 29.8 kilometers of viaducts , 26.6 kilometers of underground roads and 8.2 kilometers of surface roads. For the construction of the three lines, two Tunnel Boring Machines of the type TBM (tunnel boring machine), of 9.77 meters in diameter, were used to excavate complete section tunnels. Dhafrah was the first tunnel boring machine to start operations and Sanah was the first to reach a station. Currently, 80% of the project's progress has been achieved, obtaining constructive milestones that are relevant to the proper development of the infrastructure.
Lima Metro. Line 2 and branch line 4 (Peru). The project includes the design, construction, financing, operation and maintenance of Line 2 of the Lima Metro and a branch of Line 4, which will reach the airport, for an amount of 3,900 million euros.
