They will include an infrastructure maintenance base to service the line’s equipment, a maintenance base and depot for the automatic metro line’s trains with lengths of 45 to 60 metres, a central control room to coordinate, supervise and regulate traffic and technical facilities such as the Tour en Fosse building, electrical utility rooms and security post.
During this construction of the operation and maintenance centre, 10% of the hours worked will be set aside for people on social integration programmes. Vinci will also involve its endowment fund, Chantiers et Territoires Solidaires, which supports non-profits’ initiatives to create jobs and foster community life in the towns and cities surrounding Grand Paris Express projects.
The new Line 18 will connect Orly Airport and Versailles Chantiers within 32 minutes. The ten stations will serve south west Paris’ most strategic hubs. The line will have 35 km of which 21 km underground and 14 km of elevated crossing Plateau de Saclay.
