Barcelona Metro line 8
Overview. The pink line, mostly underground, links Plaça Espanya, in Barcelona proper, with Sant Boi de Llobregat, through L'Hospitalet de Llobregat. It opened in 1912 as a narrow gauge train line (hence predating the first metro Line 3 by 12 years), and was known as "S3" until 2003, hence the name of its suburban extended line ("S33"). It's also part of the Llobregat-Anoia and Metro del Baix Llobregat railway networks run by FGC, from which trains continue from Molí Nou-Ciutat Cooperativa onwards. There is also a freight-only branch line before Sant Boi  station that connects to the Port of Barcelona. The line first took on its current form between 1985 and 1987 when the section Cornellà-Riera – Sant Josep was first moved underground, followed by the section Sant Josep – Espanya. In 1997 Magòria-La Campana station opened, followed by Molí Nou – Ciutat Cooperativa station in 2000. An extension of the line further into central Barcelona, with a new station in Plaça Francesc Macià, has been discussed since May 1999. It would link both the metro line and the Baix Llobregat line with Trambaix routes T1, T2 and T3 and the Vallès line . The line is also projected to extend into Besòs Parc station in the Sant Martí district of Barcelona, and a branch line is also projected to link the (future) Cristòfol de Moura station with the Autonomous University of Barcelona campus via the "Horta tunnel".
