Client: SNCF Transilien
The Tram Express Ouest project is composed of two phases: a first one going from “Saint-Cyr RER” to “Saint-Germain RER” (19 km infrastructure) and a second one splitting up at “Saint-Germain Grande Ceinture” (station located on the first part of the project) to “Achères RER” (10 km infrastructure).
Each branch will have a 10 minutes headway, meaning a 5 minutes headway between the stations “Saint-Cyr RER” et “Saint-Germain Grande Ceinture”.
This line project is based on the reactivation of some section of the wide railway belt around Paris. It also integrates the planning of new urban track section in order to connect better the urban area.
SNCF Transilien has commissioned TTK to realise an operational study of each phases to:
