Avinguda Carrilet station

Avinguda Carrilet, also known as L'Hospitalet Avinguda Carrilet, is an interchange complex underneath Avinguda Carrilet, in the L'Hospitalet de Llobregat municipality, to the south-west of Barcelona, in Catalonia, Spain. It consists of a railway station on the Llobregat–Anoia Line and a Barcelona Metro line 1 (L1) station. The Llobregat–Anoia Line station is served by Barcelona Metro line 8 (L8), Baix Llobregat Metro lines S33, S4 and S8, and commuter rail lines R5, R6, R50 and R60. The services on the Llobregat–Anoia Line (including the L8) are operated by Ferrocarrils de la Generalitat de Catalunya (FGC), whilst the L1 is operated by Transports Metropolitans de Barcelona (TMB).

The original at-grade station for the Llobregat–Anoia Line was opened in 1912 by the company Camino de Hierro del Nordeste ("Notheastern Railway"). On 9 July 1985 (1985-07-09), the line's section between Sant Josep and Cornellà Riera stations was put underground and the current station started operating. The L1 station dates from 1987, when the line was extended southwards from Torrassa station. It served as the L1's southern terminus until 1989, when that line was extended to Hospital de Bellvitge station.

The platforms used by the Llobregat–Anoia Line are located between Rambla de la Marina and Plaça de la Mare de Déu de Montserrat. They comprise two island platforms, each flanked by a pair of tracks, with the two inner tracks on the main line and the outer tracks on loops off the main line. The L1 platforms are located underneath Rambla de la Marina, between Avinguda Carrilet and Carrer Prat de la Riba, comprising two 96-metre-long (315 ft) side platforms.
