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.

[5][1][6] The original at-grade station for the Llobregat–Anoia Line was opened in 1912 by the company Camino de Hierro del Nordeste ("Northeastern 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.

It served as the L1's southern terminus until 1989, when that line was extended to Hospital de Bellvitge station.

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.
