The first high-speed trains linkingBarcelonaandParistook off on Sunday (December 15), reducing the journey by nearly half the time to six hours and 25 minutes.
Two daily high-speedAVEtrains will cover the journey between Sants and La Gare, but three other routes will be offered too: Madrid -Marseillein seven hours,Barcelona- Toulouse in three andBarcelona-Lyonin five.
AVE- which means bird - connects 10 cities from north to south inSpainalready and will now link them to seven other cities in northern neighbourFrance.
The transport ministers ofSpainandFrancetravelled on the official opening journey at midday fromBarcelonatoPerpignan.
France's SNCF andSpain's Renfe will each provide 10 trains.
Prices will be between €59 (£49.78) and €170 (£143.43) and the rail network is expected to expand over 2014. SNCF says more than 30,000 tickets have already been sold forParis-Barcelona route.
The project, which was approved in 1992, will still have a slower track though betweenPerpignan and Nimes.
When that part is completed, the journey is expected to take 5 hours and 30 minutes, but that route was not expected to be covered by high-speed trains until 2030.
