Construction of sidings and manoeuvring areas at the Marne-la-Vallée Chessy station
Creation of manoeuvring areas, sidings and an improved electrical power system.

From summer 2016 through summer 2019, RATP is creating new sidings behind the Marne-la-Vallée Chessy station. This is the first phase of a project that will increase service to the stations at the far end of the Marne-la-Vallée branch. It will also help improve the regularity of the RER A.
