The first rapid transit railway service in Barcelona was founded in 1863 by the private company Ferrocarril de Sarrià a Barcelona ("Railway from Sarrià to Barcelona", after 1916 Sarrià joined the municipality of Barcelona).
Today the network consists of 12 lines managed by 2 different operators: Transports Metropolitans de Barcelona (TMB) and Ferrocarrils de la Generalitat de Catalunya (FGC, or Catalan Government Railways).
