The two platforms are linked by underground passageways.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.

Trinitat Vella is the name of a station in the Barcelona metro network, currently served by the TMB-operated L1. It's named after the neighbourhood Trinitat Vella, in the Sant Andreu district of Barcelona, and the park of the same name. It is quite unusual in being one of the few stations with an attached building overground, which lies on the Nus de la Trinitat and links the neighbourhood with Parc de la Trinitat. It was opened in 1983, when the line was extended from Torras i Bages towards Santa Coloma de Gramenet (Santa Coloma (Barcelona Metro)), and rebuilt in 1992. It can be accessed from Via Barcino and from the park.

Torras i Bages is a station of the Barcelona Metro, on L1 (red line). Opened in 1968, it serves the northern part of the Sant Andreu de Palomar neighbourhood in the Sant Andreu district. It was one of the termini of this subway line until 1983, when it was extended into Santa Coloma de Gramenet. The station does not include accessibility facilities as of 2008. It has two 107-metre-long platforms, and it is unusual for a subway station of this kind in having three railtracks as opposed to two, due to its former role as line terminus. The current railtrack leading to Fondo is actually a secondary one. The station is named after a road, Passeig de Torras i Bages (and ultimately after the 19th century bishop of Vic Josep Torras i Bages.

The Casa Bloc is a residential building built between 1932 and 1936 in the Sant Andreu district of the city of Barcelona (Catalonia, Spain). Its architects were Josep Lluís Sert (1902–1983), Josep Torres Clavé (1906–1939) and Joan Baptista Subirana (1904–1978), all members of GATCPAC (Catalan Group of Architects and Technicians for the Progress of Contemporary Architecture). Catalan architects of the Second Republic, brought together by the GATCPAC, proposed a new way of living that was just, accommodated co-existence and defended the collective identity. The creation of Casa Bloc was one of the first steps towards dignifying workers' living conditions. As a result of the Spanish Civil war, the project was cut short. In 2012, after a careful restoration by the Institut Català del Sòl and Institut de Cultura of Barcelona through the Disseny Hub Barcelona, the doors to apartment number 1/11 are open and furnished just as its creators had originally wanted.Today, the Casa Bloc is considered a symbol of the rationalist architecture in Barcelona promoted by the Catalan Government during the Second Spanish Republic, since it was once an innovative social project, integrated in the urban environment and housing functional accommodation designed as minimum standard for workers. In 1992, the Generalitat de Catalunya declared the building as a protected heritage in the category of Monuments.

Roquetes is a Barcelona Metro station, named after the nearby Roquetes neighbourhood, in the Nou Barris district of the city of Barcelona.

The single island platform is flanked by two tracks.The station was opened on 4 October 2008, when the section of line L3 from Canyelles station to Trinitat Nova station was inaugurated.The current Roquetes station should not be confused with Via Júlia station, on L4, which was known as Roquetes before 1999.

Torre Baró | Vallbona is a station on line 11 of the Barcelona Metro, serving the neighbourhoods Torre Baró and Vallbona of the Nou Barris district of Barcelona. While most of this short line is underground and single-track, Torre Baró-Vallbona is open and, as the middle station on the line, has a double track to permit trains to pass one another. Inaugurated in 2003 with the rest of the line, the station is located in hilly terrain, with the result that it has two accesses, one above and one below the station. The former is situated on Carrer Sant Feliu de Codines; the latter, on Avinguda de Vallbona, gives access to the Renfe main line station Torre Baró-Ciutat Meridiana-Vallbona, serving Rodalies Barcelona commuter lines R3, R4, and R7 and long-distance line Ca4.
