POLT Line Renewal (Paris–Orléans–Toulouse) is a rail upgrade project in France, currently under construction.
Modernizing the 700 km axis between Paris, Limoges, and Toulouse, this €3 billion program replaces aging infrastructure dating back to World War II. SNCF Réseau is upgrading power supplies and signaling to increase speeds to 160 km/h and improve reliability for 2.6 million annual passengers. The renewal project targets full deployment of new "Oxygène" trainsets by late 2027.
Construction began in 2018, with completion expected in 2027.
The project has an estimated investment of €3.00B.
