The Barcelona tram system consists of six lines divided in two networks - Trambaix and Trambesòs.
The Trambaix network comprises lines T1, T2 and T3 and connects Plaça Francesc Macià with towns to the south of Barcelona, such as L’Hospitalet de Llobregat, Esplugues de Llobregat, Cornellà de Llobregat, Sant Joan Despí, Sant Just Desvern i Sant Feliu de Llobregat
Trambesòs connects Glòries with the coast north of Barcelona with lines T4 and T6 going to Sant Adrià de Besòs and T5 going to Badalona.
There are plans to connect the Trambaix and Trambesòs networks by building a new line along Avinguda Diagonal.
The tram network is operated by Tramvia Metropolità, SA better known
as TramMet, and forms part of the Barcelona Metropolitan Transport
system - TMB - so regular tickets are valid from Barcelona tram
At the time of writing, a single journey in Zone 1 will cost €2 and a ten-journey T10 ticket will cost €10.20.
An excellent option for a tourist spending a few days in Barcelona is a 2-Day, 3-Day or 4-Day Barcelona Card, which not only includes tram, metro, bus and local train journeys but also free or discount entrance to many of Barcelona's most popular sights.
The Trambaix includes three different routes - T1, T2 and T3.
The tram route starts at Plaça Francesc Macià in Barcelona to the west of the city and extends west, passing L'Hospitalet de Llobregat, Esplugues de Llobregat, Cornellà de Llobregat, Sant Joan Despí and Sant Just Desvern.
An extension of T3 opened on December 8, 2006, as far as Consell Comarcal in Sant Feliu de Llobregat.
The yearly ridership of all the Trambaix lines combined was 15,057,318 passengers in 2008.
The network consists of three routes that connect the district of Sant Martí in Barcelona to Badalona and Sant Adrià de Besòs municipalities.
The first section of Trambesòs was opened on 8 May 2004 as part of route T4 and since its opening it has undergone several extensions, the last of which took place on 15 June 2008 with the creation of route T6 between Sant Adrià de Besòs railway station and Gorg metro station in Badalona.
The yearly ridership of all the Trambesòs lines combined was 7,985,513 passengers in 2010.
