The machine has now excavated over 1,650 meters of the 3,854 meters planned from its starting point at the Colomiers Gare shaft.

The TBM is now advancing towards the Saint-Martin du Touch station, with the final objective of reaching the Laporte shaft.

We wish the Jeanne Marvig TBM and its crew continued success for the remainder of their journey.
