The railway from Paris to Bordeaux is an important French 584-kilometre long railway line, that connects Paris to the southwestern port city Bordeaux via Orléans and Tours. The railway was opened in several stages between 1840 and 1853, when the section from Poitiers to Angoulême was finished. 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 LGV Atlantique is a high-speed rail line running from Gare Montparnasse in Paris towards the Atlantic coast of France. It opened in 1989–1990 and has two intermediate stations: Massy TGV station and Vendôme-Villiers-sur-Loir TGV station. It divides into two parts at Courtalain, one going westward to Le Mans, the second one going southwestward to Tours. Both branches have been extended, by the LGV Bretagne-Pays de la Loire and the LGV Sud Europe Atlantique.
