SPAIN APPEARS AS ONE OF THE MAIN SUPPLIERS OF STATE-OF-THE-ART SUBURBAN AND LIGHT RAIL NETWORKS.
The implementation of this extensive diversity of urban systems has led to an extremely high degree of excellence. The combination of cutting-edge technology from Spanish infrastructure companies means that the country also appears as one of the main suppliers in state-of-the-art suburban and light-rail projects. Examples of this are important projects and works of extraordinary technical complexity, such as the Riyadh or Stockholm Metropolitan Railways, which include a deep tunnel in rock under the sea.
