Overview

Line 5 (L5), commonly called Línia Blava or the Blue Line, is one of the core lines of the Barcelona Metro. Operated by Transports Metropolitans de Barcelona (TMB), it runs between the termini Cornellà Centre and Vall d'Hebron and is included in the Autoritat del Transport Metropolità (ATM) integrated fare system. The line serves both central Barcelona and adjoining suburbs, providing frequent urban rapid-transit service.

Characteristics

L5 is represented in blue on official maps and station signage. It is a conventional metro line designed for high-capacity, short-interval operation and is primarily underground through the dense urban core. Stations vary in size and layout, and many have been upgraded to improve accessibility and passenger information.

History and development

The line was built and extended in phases, reflecting Barcelona's post-war growth and later suburban expansion. Over decades it has been modernized to accommodate increasing ridership and to integrate with newer sections of the city's transit network. Refurbishment programs have targeted signalling, platform facilities and accessibility features.

Route, interchanges and services

L5 provides important cross-city connections and links with other metro lines, tram services and regional rail. Key interchange stations allow passengers to transfer across the network and to commuter lines. As part of the broader Barcelona Metro system passengers can consult the network map and service updates via the official Barcelona Metro network information channels.

Uses and importance

The line carries commuters, students, shoppers and visitors, supporting daily mobility for residents in both central districts and neighboring municipalities. Its role in easing road congestion and connecting residential areas to employment, education and leisure sites makes it a vital element of the city's public-transport offer.
