After years of uncertainty, the high-speed line between Bordeaux and Toulouse takes a decisive step forward. The government confirms its commitment and is concretely launching the project. The LGV project is progressing, but not at high speed.

On May 7, 2026, in Toulouse, Prime Minister Sébastien Lecornu signed a protocol marking an “irreversible commitment” of the State for the LGV Bordeaux-Toulouse, with an initial budget of 500 million euros to kick off the works and calls for tenders.

A Journey Filled with Challenges Resumed

The South-West LGV is entering its operational phase. Calls for tenders are to be launched by the end of 2026, following the validation of the financial setup expected in the coming weeks. Preliminary works have already begun in certain areas, and the service launch is anticipated around 2032-2033, although a slight delay towards 2035 remains possible.

A 220 km Line Between Bordeaux and Toulouse

The project plans for the construction of 220 kilometers of new line between Bordeaux and Toulouse, integrating...

Several new stations are planned, particularly around Agen, Montauban, and potentially Mont-de-Marsan (on the branch towards Dax). The level of service (direct TGVs or intermediate stops) is still to be decided, which is a key point for the concerned regions.

A major challenge for the Southwest at 14 billion euros

The total cost is estimated at 14 billion euros, with a 40% contribution from the State, 40% from local authorities.cute; locations and 20% for the European Union. An initial envelope of 500 million euros is unlocked immediately to kick off the procedures and secure the timeline.

After nearly 40 years of discussions, the project is finally entering a concrete phase. Now, it's time to turn the political commitment into visible construction... and then into a service line.
