On the 7^th of February the shield for the fourth TBM, which will drive 3.4 km of the Line 15 South for the Grand Paris Express was lowered into place. The TBM will begin its journey at what will be the future station for Arcueil - Cachan. The TBM, whose name is not yet known, will begin to dig in April, it will tunnel through the future Villejuif Institut Gustave-Roussy station and exit from Villejuif Louis-Aragon station. Along the route the TBM will encounter several cavities that will be filled with mortar injections. 

Ellen, the third TBM working on the Grand Paris Express, began digging on February 14th from the entry pit at Robespierre in Bagneux. This work is under the supervision of the CAP group’s team, led by Vinci Construction, it will drive 4 km to Fort Issy - Vanves – Clamart station with a 10-15 m / day average. Once this section is finished, Ellen will excavate an additional 900 m to the future Arcueil – Cachan station, where construction works are underway.
