Paris Austerlitz is one of the six large terminus railway stations in Paris. It is situated on the left bank of the Seine in the southeastern part of the city, in the 13th arrondissement. It is the start of the Paris–Bordeaux railway; the line to Toulouse is connected to this line.
Since the introduction of the TGV Atlantique — using Gare Montparnasse — Austerlitz has lost most of its long-distance southwestern services. It is used by some 30 million passengers annually, about half the number passing through Montparnasse.
The Elipsos Train Hotels (Trenhotel) operated jointly between RENFE and SNCF operated from here to Madrid and Barcelona. They would leave in the early evening and arrive next morning. With the start of a direct TGV from Paris to Barcelona, on 15 December 2013, the Trenhotel services finished.
