The modern Sants station was built in the 1970s as part of construction of the second east-west regional line running under the centre of Barcelona. The first east-west railway to Estació de França terminus, more to the north,[3] was covered up and is now also in use as a railtunnel for the regional and long distance trains. Over the last 30 years, Estació de Sants has since eclipsed the earlier França terminus (Barcelona Estació de França), from the 1920s, as Barcelona's main railway station.
