La Sagrera-Meridiana, simply known as La Sagrera, is an interchange complex underneath Avinguda Meridiana, in the Barcelona district of Sant Andreu, in Catalonia, Spain. It consists of a Rodalies de Catalunya station and three Barcelona Metro stations. The Rodalies de Catalunya station is located in the Meridiana Tunnel on the Lleida to Barcelona via Manresa railway, between Sant Andreu Arenal and Arc de Triomf, and is operated by Renfe Operadora. It is served by Barcelona commuter rail service lines R3 and R4, as well as regional rail line R12. The Barcelona Metro stations are on lines 1 (L1) and 5 (L5), as well as the northern section of line 9/10 (L9 Nord/L10), and are operated by Transports Metropolitans de Barcelona (TMB). On the L1, the station is between Navas and Fabra i Puig, on the L5 between Camp de l'Arpa and Congrés, and on the L9/L10 between Plaça Maragall (future) and Sagrera - TAV (under construction). The station is also projected to become the terminus of the L4 once the extension from La Pau opens. A number of interurban bus services stop near the station. From Wikipedia
