Toulouse Metro: TBMs Lise Enjalbert and Berthe de Puybusque Resume Tunneling Operations

A major milestone has been reached in the construction of the future Line C of the Toulouse Metro.

Last month, the Tunnel Boring Machine (TBM) Lise Enjalbert completed its second breakthrough at the future Blagnac station, after tunneling more than 2,000 meters from the Ponts Jumeaux starting shaft. It will now begin excavating the remaining 1,867 meters between Blagnac station and the Laporte exit shaft.

In parallel, the TBM Berthe de Puybusque is starting the second section of its journey, between the La Vache Gare–Le Grand Marché and Raisin stations. This phase includes passing through the Lycée Toulouse-Lautrec station, with a final 2,122 meters scheduled for completion.

Our third TBM, Jeanne Marvig, which is operating on the section between Fontaine Lumineuse and Saint-Martin-du-Touch stations, has also resumed its advance toward its final destination, the Laporte shaft.

Congratulations to our teams mobilized on these key operations!
