On 20/07/20 the TBM Koumba arrived at the future Europa service facility in Orly on the extension of line 14 south: click here for the video.  The TBM will resume excavation in about two weeks' time, after an overhaul. The TBM will then tunnel towards Pont de Rungis station for another 800 m, from where it will be extracted. The Koumba TBM, which started in June 2019 from the Morangis well, has completed 3.2 km of the 4 km long South section between the Morangis depot/maintenance site and Pont de Rungis station, of the extension of line 14 south which is part of the Grand Paris Express project.
