The stations on Line 9 of Barcelona’s underground were built under the formula of the public-private concession. They were divided into four sections for this tender, with three finally adjudicated to different operating companies. Ineco was the technical advisor to the banks of the concession of each of the three sections awarded.
This metro line is the longest suburban automatic train operation line in Europe and it is the first non-radial line of the metropolitan railway of Barcelona. It has a total length of 47.8 kilometres, mostly with circulation of trains at two levels. The line will boast a total of 52 stations, some of which will be located 60 metres below ground. These stations will serve as connection points with the rest of the underground lines, regional railways (FGC and Renfe) and the tram. The line will travel around the centre of Barcelona, thus notably enhancing the efficiency of the current metropolitan transport network.
