The €14 billion project is part of plans to improve public transport services in the south-west

The new ligne à grande vitesse (LGV) is the first step in a project that will include 220km of track, two new stations (in Agen and Montauban), intervening stops, and connections between the train and local metro, bus, and bike systems.

The line is set to enter service in 2032.

The project - which will cost €8 billion for the Bordeaux-Toulouse section alone - will also see a €4 billion line between Bordeaux and Dax.
