The consortium includes Revenga Ingenieros and FCC Industrial e Infraestructuras Energéticas.

The contract involves the Tarragona - Vandellós section of the Mediterranean Corridor and its connection with the Madrid-Barcelona-Perpignan high-speed line and covers installation of ERTMS Level 2 signalling using CAF's Auriga system, fixed telecommunication systems, centralised traffic control, and auxiliary safety and protection systems.

Construction of the Tarragona – Vandellós high-speed line started in 2000, but work was halted for nearly a decade, and the line has still not been completed. It was originally intended to install standard-gauge track but Adif has now decided to lay dual-gauge track, as the rest of the Mediterranean Corridor will be dual-gauge. The line will be electrified at 25kV ac and will be equipped with both ERTMS Level 2 and Spain's Afsa signalling system. Main infrastructure highlights include the 1.9km Rojales tunnel and the 1.2km Francolí viaduct together with the L'Hospitalet de l'Infant station.
