Comprehensive project to build three new metro stations.
The expansion of Line 5 of the Barcelona metro involves 2.6 km of new tracks and three new stations: Carmel, Teixonera-Coll, and Valle Hebrón. This links to Line 3 and the Sant Genis train depot with an electrical substation and the Valle Hebrón shunting area. This meant an investment of 320 million Euros, and currently it services 30,000 users per day.
The facilities pass through the 3 km of tunnel. The new section of metro runs 25 kW and 6 kW and is cabled and powered from the tunnel itself, containing fibre optics and radiant cables, among other facilities.
A noteworthy feature of these facilities is their extensive communications network, each station being equipped with two communications rooms (main and auxiliary). During this project we also provided services related to HVAC, plumbing, fire detection and extinguishing, remote control of fixed facilities, rate and toll system, video surveillance, access doors, and controlled access.
