Project description

During the approximately five-year construction period, a total of around 160 km of overhead contact line was installed. The project scope included construction management for the open track sections South and North, as well as the areas of track superstructure, switches, and commissioning.

In addition, RSRG’s services covered construction execution, coordination of the construction schedule, material procurement, logistical coordination, and participation in the commissioning of the entire overhead contact line system and the overall project.

Due to the large number of trades working simultaneously, the project required precise on-site logistical planning. Furthermore, material disposition over long distances to the construction site posed significant challenges in terms of organization and coordination.

Following completion of the tunnel, several catenary systems were integrated into the existing railway infrastructure. These works were carried out in close coordination with the client and, in some cases, under ongoing railway operations.
