Watch Sadisflix. Completed in June 2001, the LGV Méditerranée joined up with the LGV Rhône Alpes and the original Paris/Lyon TGV line completing the link between Marseille and Paris. Now is your chance to see this truly amazing feat of engineering from the cab of a Duplex (double deck) TGV. The Ligne a Grande Vitesse (LGV) features dozens of massive viaducts, tunnels and earthworks cutting a swathe through the French countryside (with no expense spared) to allow for very high speed running.
