The Trambaix (Catalan pronunciation: [tm'ba?]) is one of Barcelona's three tram systems. It is operated by TRAMMET connecting the Baix Llobregat area with the city of Barcelona, Catalonia, Spain. It opened to the public on 5 April 2004 after a weekend when the tram could be used free of charge.
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 Tram T3 opened on 8 December 2006, as far as Consell Comarcal in Sant Feliu de Llobregat. The yearly ridership of all of its lines combined is of 15,057,318 passengers as of 2008.
Tram connection proposed
Since the modern tram system started in 2004, the possibility was envisaged to connect Trambaix and Trambesòs. In September 2008 the mayor of Barcelona, Jordi Hereu, said in a TV programme that in the near future (2011-2012) both trams will be connect over the Diagonal Avenue. Recently, the Generalitat de Catalunya (Catalonia's government) was planning that project, but it is now on hold. But in January 2019, Barcelona's mayoress, Ada Colau approved the project.
