Grand Paris Express project promoter Société du Grand Paris has announced that assembly of the third tunnel boring machine (TBM) for Line 15 South has started to be assembled at Bagneux.
The name for the TBM, wchosen by pupils at the Henri Wallon B School, is expected to be revealed at a special community event on 1 December.
Société du Grand Paris has said that Bagneux TBM will start driving the 4km tunnel from the site to Issy-Vanves-Clamart Fort station in January next year and is expected to complete the drive in 2020. Before the TBM can bore the full length of the tunnel, grouting work of former mines in the Bagneux and Malakoff districts must be completed.
The first TBM to be launched, Steffie Orbival, was launched in April and is currently achieving advances of 10m to 12m per day and is scheduled to make its first breakthrough in spring next year.
The second TBM is named Malala and was launched in August. The TBM has driven the first 100m of its 4.9km drive to Bry - Villiers - Champigny station where it is expected to breakthrough in summer 2020.
According to Société du Grand Paris, 16 TBMs out of 21 machines planned for the project will be operating on the project by the end of 2019.
