This article's factual accuracy may be compromised due to out-of-date information. The reason given is: L4 and L11 no longer share an island platform: L11 now has their own (narrow) island platform. Please help update this article to reflect recent events or newly available information.(April 2022)
Lines L4 and L11 share a single island platform, which is located underneath Carrer Aiguablava. Trains on line L4 enter and leave from the south end of the platform and normally terminate on the eastern side of the platform, whilst trains on line L11 enter and leave from the other end and terminate on the other side of the platform. Line L3 uses a separate 100-metre (330 ft) island platform, situated between Carrer Aiguablava and Carrer Chafarinas. The two platforms are linked by underground passageways.[3][4][5]
The first section of the station was opened in 1999, with the extension of L4 from what is now Via Júlia station. Line L11 was opened in 2003, as a light rail extension to line L4, towards Can Cuiàs station and sharing line L4's platforms. Line L3 arrived at Trinitat Nova on 4 October 2008, with its own platforms.[2][4]
