The bus station in Barcelona is next to Estacio del Nord http://www.barcelonanord.com/ (which is no longer a train station and is now an exhibition centre). The nearest Metro station is Arc del Triomf on red Metro line 1 exit Carrer de Nàpols.

There is also a bus service between Lleida and Pobla/Tremp.

If you do intend to use the Spanish railways network and are over 60 years of age then it is worth purchasing a Tarjeta Dorada (which is a Spanish over sixties rail card) as savings can be from 25-40% off train ticket prices. The Tarjeta Dorada only costs about 5 Euros per person for a year and can be bought from the main railway stations prior to buying the tickets. All that is needed is a proof of identity and age with a passport or identity card. You do not need to be a resident. This card is also valid on the AVE
