SEAT lets the train take the strain

SEAT by Train from the Martorell Factory to the Port of Barcelona The building of this project started in 2005 -  a joint venture between SEAT and Autometro – as an innovative way to transport cars from the factory to the port, and has made a big difference to the traffic on Catalan roads in that time, taking more than 20,000 lorries off the roads and racking up a big saving in SEAT’s carbon footprint. Throughout 2008 the rail link transported cars on twice daily runs on double-decker carriages over 400 metres long, carrying more than 170 cars at a time. Try doing that on the roads!
