CAP is working on contract TC3 on Line 15, which is a new circular metro that formed part of 200km of new metro route planned to be in service by 2030 under the Grand Paris Express project.
The shaft at the Arcueil-Cachan station yard will be used to launch the Herrenknecht tunnel boring machines that will drive the 8.2km twin bore tunnel. The TBMs will drive through Villejuif Institut Gustave-Roussy station, where the new Line 15 intersects with an extension of Line 14, to emerge at Villejuif Louis-Aragon train station.
The TBMs are expected to arrive at the Arcueil-Chachan site in early 2019 and the tunnel drive is expected to take 16 months.
