As part of the Primavera Sound festival, the Trambesòs line T4 will run non-stop during the festival. On Thursday, Friday and Saturday of the first and second weekend the service will run non-stop. As a result, TRAM provides sustainable mobility for those attending this important music festival, which is mainly held in the Forum area.

The increase in the service comes as a result of a collaboration agreement, renewed for the fifth year with the organisers of the cultural event. Thanks to this agreement, there will be trams running without interruption for two weekends on the T4 line that runs from Estació de Sant Adrià to Ciutadella | Villa Olímpica.

The timetables for this line will be as usual and from midnight on Thursday night and 2 am on Friday and Saturday, running every 20 minutes. At specific times, such as at the end of the headline concerts, there will be double trams running to facilitate the departure of music festival-goers.
