Alstom has been selected by Société du Grand Paris, in agreement with Île-de-France Mobilités, to supply the rolling stock for Line 18 of the Grand Paris Express network. The contract also includes solutions for driverless automated systems, data transmission, centralised supervision controls and the overall integration of the transport system. The contract is worth approximately 230 million euro1. The contract is co-financed by Société du Grand Paris and Île-de-France Mobilités, which is responsible for the rolling stock and on-board equipment. Line 18 is a 35-kilometre automatic metro line, including 14 kilometres of overhead lines, which will eventually link Versailles to Orly airport in 30 minutes, passing through the Saclay plateau, well-known for its major education and research centres. Alstom is deploying a complete signalling system for Line 18 of the Île-de-France network, comprising three types of technology: Urbalis Fluence automatic train control, an innovative solution based on direct train-to-train communication, brings the intelligence of the system on-board the trains and improves the line’s overall performance by reducing intervals between trains. Iconis centralised controls allow for automated traffic management with a high level of operational flexibility, enabling operators to develop advanced regulation scenarios. The data transmission system, based on robust, proven products, offers very high availability. For Line 18, Alstom will also act as general integrator, which includes the verification of the tests for the different sub-assemblies and the organisation of the overall system tests, including the functional realisation of the overall tests and the verification of the entire transport system’s performance.
