Barcelona is a hub for RENFE , the Spanish state railway network, and its main suburban train station is Sants Estació (which is under renovation and enlargement at present in order to prepare for the arrival of the AVE system). The AVE high-speed rail system was recently extended from Madrid to Lleida in western Catalonia, and is expected to reach Barcelona by 2007. Renfe and the Ferrocarrils de la Generalitat de Catalunya (FGC) run Barcelona's widespread commuter train service. Barcelona's transit company, Transports Metropolitans de Barcelona (TMB), runs the Barcelona Metro system and city bus . See List of Barcelona metro stations . Barcelona has recently adopted another transport option with two new tram lines known as Trambaix and Trambesòs .
