Grand Paris Express Line 18: a major milestone reached!

The project has reached a new milestone with its handover to technical operations to Île-de-France Mobilités and RATP-GI (RATPgroup), in the presence of Keolis Compagnie du Métro du Grand Paris – Ligne 18, the future operator, and our partner Alstom.

After ten years of studies, works and testing, this milestone marks the culmination of a considerable collective effort: construction of tunnels and France’s longest railway viaduct, building four stations, and integrating all systems.

JFS Architectes, the project architect, is proud to have contributed to this major Grand Paris Express operation as part of the ICARE design team led by Ingérop.

A new phase now begins with trial running, ahead of the arrival of the first passengers between Massy-Palaiseau and Christ-de-Saclay.

Congratulations to all teams for the work accomplished!
