It runs southwards from the Barcelona area to the town of Tortosa, passing through the Vallès Occidental, Baix Llobregat, Garraf, Baix Penedès, Camp de Tarragona, Baix Ebre and Montsià regions.

R16 trains run primarily on the Valencia−Sant Vicenç de Calders railway, using Tortosa and/or Ulldecona-Alcanar-La Sénia as their southernmost terminus, and Barcelona Estació de França as its northern one.

History
The current line scheme of the R16 started operating on January 1, 2010, after the transfer of the services from Media Distancia Renfe to the Generalitat of Catalonia. Earlier, all the regional rail services carrying out the line Barcelona-Tarragona-Tortosa-Ulldecona were branded as Ca1 for the Catalan rail division, and 32 in the nationwide regional rail network. Its initial alignment used the line close to the coast passing through Salou, Cambrils and L'Hospitalet de l'Infant. On 13 January 2020, the line's alignment was partially altered, 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. The coastal line segment from Tarragona to Port Aventura was taken over by, which came into service the same day.
