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.

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.
