Apart from the transport links to the airport, the town of El Prat is served by a railway station on the coast line from Barcelona to Valencia.

After this, the installation of a ferry to cross the river and, later, the construction of the Ferran Puig bridge, the arrival of the railroad and the discovery of underground water improved the communication of El Prat and consequently doubled its population.

In 1917, the installation on the town of La Papelera Espanola, a factory producing paper and derivatives, started the industrial years of El Prat.

That was the beginning of the connection between El Prat and the world of aviation, that would end up creating Barcelona International Airport after the unification of the three aerodromes in 1948.

In 1926, another company, this time of the textile sector, called "La Seda de Barcelona", built a factory in the town.
