The sections Paris–Orléans and Orléans–Bordeaux were built and exploited by two different companies, that became part of Chemin de Fer de Paris à Orléans in 1852. The first section that was opened in 1840 led from Paris to Juvisy-sur-Orge, a southern suburb. The line was extended to Orléans in 1843. Tours was reached in 1846, and Poitiers in 1851. In 1852 Bordeaux was connected with Angoulême. Finally in 1853 the section from Poitiers to Angoulême was opened. The Gare d'Austerlitz is the original terminus of the Paris–Bordeaux line. At the occasion of the 1900 Exposition Universelle the Gare d'Orsay was opened as the new terminus, with a more central location. The richly decorated Gare d'Orsay was only used by electric trains. After 1939 it was only used for suburban trains. Since 1986, the station building is a museum of 19th-century art.
