RT2 (Rodalies de Catalunya)

The RT2 is a line of Rodalies de Catalunya's Tarragona commuter rail service, operated by Renfe Operadora. It links Port Aventura railway station in the Costa Daurada area with L'Arboç railway station, in Baix Penedès, through the city of Tarragona. The RT2 shares tracks for most of its length with regional rail lines, and , as well as Barcelona commuter rail service line.

RT2 services started operating in 2014, initially running between L'Hospitalet de l'Infant and L'Arboç stations, again through Tarragona. It became the first commuter service to use the Valencia-Sant Vicenç de Calders railway, originally designed to serve regional as well as inter-city rail. On 13 January 2020, the RT2 was shortened, so that it began to operate in its current configuration. This shortening came up as a result of the opening of a new inland line between Tarragona and L'Ametlla de Mar, and the closure of the coastal line beyond Port Aventura.
