Cercanías San Sebastián (Basque: Donostiako Renfe Aldiriak) is a commuter railway service provided by Renfe serving the city of San Sebastián and towns in the interior of Gipuzkoa[2] in the Basque Country, Spain. It serves around six million passengers a year.
This railway service uses the Madrid–Hendaye railway line, serving 30 stations. Dual gauge is being installed in the section between Astigarraga and Irun.[3] When completed, it will be possible to extend the commuter rail service to Bayonne in France.[4] Despite running parallel to Euskotren's suburban service between San Sebastián and Irun, the lines lack a proper interchange station, with only out of station interchanges available. The construction of a new station at Riberas de Loiola has been proposed, this station would add a direct connection between the two networks.[5]
