Alstom completes Recoletos Tunnel Project in a record

Alstom has completed, the record time of five months, the project to modernize the signalling of the Recoletos Tunnel, in the section of the tunnel between Atocha and Chamartín, in Maddrid, Spain. The project has included the complete renovation of the signalling and protection systems (ASFA Digital), the installation of new fixed communications systems, as well as the coordination and synchronization with the other works being carried out in the infrastructure at the same time (roads and catenary).

Over seven kilometres in length, the Recoletos Tunnel is a key infrastructure for the Spanish railway network. This is the tunnel that supports more traffic in the entire network, with about 3,290 weekly circulations (98% are suburban trains).
