The exclusive use of the reserved platform by the tram is meant to provide greater regularity, speed and safety, and it only has contact with other vehicles at several existing at-grade intersections with the local street system.

The rolling stock operated on the network is composed of 18 Citadis 302 low-floor trams built in its variation "Barcelona" (teal and white colors) by Alstom at its manufacturing plant in Santa Perpètua de Mogoda.

[10] Tram units are parked and maintained at the only depot of Trambesòs located next to Central Tèrmica del Besòs stop, on a triangular piece of land between the Ronda Litoral coastal beltway and the Barcelona–Mataró–Maçanet-Massanes railway.

[26] In 2008, the Mayor of Barcelona Jordi Hereu announced the refurbishment of Avinguda Diagonal, which included the construction of the new tram line.

[30] The development of the referendum was marked by fierce controversy from day one, and specially because of continuous technical faults involving the electronic voting system.

After the failed referendum, there was a political crisis of the Barcelona City Council which resulted with the resignation of two politicians from the local government team, and the linking of the two tram networks appeared to have stagnated.

[31] The succeeding local government, headed by Xavier Trias in 2011, dismissed the proposal of connecting Trambaix and Trambesòs through Avinguda Diagonal, though it has been agreed to reactivate the linkage project with the Generalitat.

Mayor Ada Colau continued promoting the connection of the TRAM along the Avinguda Diagonal, however was defeated by opposition parties when she presented the proposal to the city council in 2018.

[36] Incumbent mayor Jaume Collboni was initially hesitant about the final swift connection, voicing his concerns with the current L8 extension works at Plaça de Francesc Macià, Avinguda Diagonal, with Catalan Minister of Territory Ester Capella coming out denying any sort of incompatibility.

[38] On 13 November, 3 days after the public opening of the new tram extension from Glòries to Verdaguer it was reported that Mayor Collboni planned to split the final 2 km in two stages: the first up to Passeig de Gràcia (1 station) and the second to Francesc Macià (3 remaining stations), with the City Council government focusing "in the first stage for now" and "not the latter".

[39] The Infrastructure Master Plan (PDI) 2011–2020 by the Autoritat del Transport Metropolità (ATM) for Barcelona metropolitan area includes various proposals to extend the existing tram network.

Trambesòs is one of the public transport networks in Barcelona metropolitan area with one of the highest rates of fraud, incivility and vandalism This results in €275,000 per year in added expenses for TRAM.

[46][47] After this controversial aggression, TRAM decided to strengthen security on the network, mainly at Gorg, Estació de Sant Adrià and Ciutadella – Vila Olímpica stops.

[48] It was also decided to rely on popular mediators who are natives from the affected area and selected by the Federation of Gypsy Associations in Catalonia (Fagic) to minimize vandalism, making possible to solve several conflicts.
