In Barcelona, the metro gets most of the attention, but once you need the airport, the coast, Sant Cugat or Montserrat, you are on the suburban rail network. The two systems to know are Rodalies and FGC, and both are useful if you live in or around Barcelona.
Rodalies de Catalunya is the regional commuter network run by Renfe on behalf of the Generalitat. Its lines use R numbers, such as R1, R2, R3 and R4, and they fan out from central Barcelona stations, mainly Sants and Passeig de Gracia, towards the coast and inland towns.
FGC, Ferrocarrils de la Generalitat de Catalunya, is the Catalan government’s own railway. It runs two suburban networks into Barcelona that do not physically meet, the Barcelona-Vallès line from Placa Catalunya and the Llobregat-Anoia line from Placa Espanya. Its inner services are numbered like metro lines, including L6, L7, L8 and L12, while longer-distance services use S and R numbers.
For most people, a few lines do most of the work. On Rodalies, R1 goes up the coast through Badalona and Mataro to the Maresme beach towns, including Arenys de Mar, Calella and Blanes. R2 Nord is the key airport line, serving Barcelona-El Prat Airport every half hour and stopping at Sants and Passeig de Gracia. R2 Sud heads south-west to Sant Vicenc de Calders and the Garraf coast, including Sitges and Vilanova i la Geltru. R3 and R4 go inland and north, while R7 and R8 are short orbital links, mainly useful for Universitat Autonoma at Cerdanyola.
FGC is simpler once you separate the metro-style lines from the outer ones. L6 goes to Sarria, L7 to Avinguda Tibidabo, where the funicular to Tibidabo starts, L12 runs from Placa Catalunya, and L8 runs from Placa Espanya. These all sit inside Zone 1, so any integrated ticket that works on the metro also works here. S1 goes to Terrassa and S2 to Sabadell, with stops including Sant Cugat and the Universitat Internacional. From Placa Espanya, S3, S4, S8 and S9 serve the inner Baix Llobregat suburbs. The longer interurban FGC lines are R5 and R50 to Manresa, and R6 and R60 to Igualada, with the R5 also used for Montserrat connections.
The fare system is integrated, and that is what saves money. Barcelona’s public transport uses the ATM zonal system, with the city in Zone 1. The same ticket can work on the metro, buses, the tram, FGC and Rodalies, as long as your journey stays within the zones covered by the ticket. You do not need a separate Rodalies ticket for a Zone 1 trip. The main travel titles are now loaded onto the contactless T-mobilitat card, which is replacing the old paper tickets.
The airport is the main exception to remember. The fastest rail link from the city centre is the R2 Nord Rodalies train from Sants or Passeig de Gracia. For official journey planning, use Rodalies de Catalunya and FGC. If you want the fare rules and zone map, the ATM site is the source to check before you travel.
