Metro and regional rail

Barcelona is served by an extensive local public transport network that includes a metro system, a bus network, a regional railway system, trams, funiculars, rack railways, a Gondola lift and aerial cable cars. These networks and lines are run by a number of different operators but they are integrated into a coordinated fare system, administered by the Autoritat del Transport Metropolità (ATM). The system is divided into fare zones (1 to 6) and various Integrated Travel Cards are available.

The Barcelona Metro network comprises twelve lines, identified by an "L" followed by the line number as well as by individual colours. The Metro largely runs underground; eight Metro lines are operated on dedicated track by the Transports Metropolitans de Barcelona (TMB), whilst four lines are operated by the Ferrocarrils de la Generalitat de Catalunya (FGC) and some of them share tracks with RENFE commuter lines.

In addition to the city Metro, several regional rail lines operated by RENFE's Rodalies de Catalunya run across the city, providing connections to outlying towns in the surrounding region.
