Double track system with ballasted tracks, Length: 450 m, Short and long distance railway traffic

Construction of 3 structures under double track railway line, one for road traffic and the other two for pedestrians. The main caisson was cast-in-place and pushed under the existing railway, the pedestrian caissons built using two prefabricated caissons and pushed and the tracks with slurry walls coming out under crossing.

Other works include access roads, urban infrastructures around the level crossing, lighting infrastructures and improvements in the local drainage.

More detailed track works may include:

Updating of sleepers

Installation and retrieval of temporary beams  and trac supports

Excavation under tracks

Instalation of ballast

Installation and retrieval of track supports

First Levelling

Alignment and profiling os track

Second Levelling

Dynamic stabilization

The section Nudo de Bobadilla (Antequera), Phase II, has a length of 6.15 km and runs through the town of Antequera, in Málaga province. The proposed works involve the implementation of the platform of the High Speed Line Antequera-Granada. In this section there are junctions that allow the connection of Málaga and Granada at high speed. The project includes the necessary actions for the implementation of infrastructure works such as earthworks, drainage, structures, replacement of services and easements, and construction of cross connections to ensure patency of the line road. The new layout has been designed for high speed double track standard gauge and for exclusive passengers traffic. It´s worth mentioning, as unique elements, the 74m. pergola on the Córdoba-Málaga High Speed Line and the 258 m. Viaduct over the Arroyo de Las Lomas, box section post-tensioned panel executed in situ. The Bobadilla Node is the key point of connection between the future Andalusian cross passage at high speed, to which the High Speed Line Antequera-Granada belongs, and the High Speed Line Madrid-Córdoba-Málaga. It also represents an essential core at the joint of the rail network in Andalusia to the rest of the peninsula.
