 The opening of the LGV Atlantique high speed line from Paris to Tours in 1989 has decreased the importance of this section of the line for passenger traffic; the opening of the LGV Sud Europe Atlantique in 2017 has seen all long distance passenger trains migrating to that line and leaving space for more regional and local trains, as well as freight trains.The Paris–Bordeaux railway leaves the Gare d'Austerlitz in Paris in southeastern direction.It follows the left Seine bank upstream until Juvisy-sur-Orge, where it starts following the small river Orge upstream.
