The FGC (Ferrocarrils de la Generalitat de Catalunya) trains largely provide transport to suburban areas, leaving from 2 important hubs: Plaça de Catalunya & Plaça de Espanya. They may, however, be convenient for traveling around the city center as well.
Prices increase depending on the zone, 1 being the center, progressing outwards to 6. Note that you may use integrated passes by zone valid for the metro, bus and FGC.
