Platja de Castelldefels is a Rodalies de Catalunya railway station serving the beach district of Castelldefels, in Catalonia, Spain. It is located at about 2 kilometres (1.2 mi) south of the main town and less than 200 metres (660 ft) from the beach, making it very busy during the summer months but almost deserted in winter. It is served by some trains on Barcelona commuter rail service line R2 Sud. From Wikipedia
