R8 trains started operating on 26 June 2011 (2011-06-26) after a service restructuring affecting the Barcelona commuter rail service. The R7, which had previously run between Martorell and L'Hospitalet de Llobregat stations via Vallès Occidental and Barcelona, was shortened and started operating between Cerdanyola Universitat and Barcelona Sant Andreu Arenal stations. The newly created R8 took over the former route of line R7 between Martorell and Cerdanyola Universitat stations, then continuing eastwards to Granollers Centre railway station, without entering Barcelona.[4][5]
