Line 18 will connect Orly airport to Versailles by 2030, serving along the way the Innovation and Research clusters of the Saclay Plateau, as well as large residential areas and labour pools in the Yvelines and Essonne “départements”. The line will offer interconnection points with RER lines B and C, and with the extended Line 14 at Orly airport. In 2024, the Line 18 will serve Orly airport / CEA Saint-Aubin, while in 2030 the extension to Versailles Chantiers will be operational.
