RER A, service disrupted this summer: what are the alternatives to reach Disneyland Paris?

Because of scheduled works on the RER A this summer, service on this RER line is suspended between Vincennes and Noisy-le-Grand Mont d'Est for the entire day from August 8 to August 23, 2026 inclusive. A setback for regular commuters on the line, but also for visitors heading to Disneyland Paris during this period.

In practical terms, no trains will run between Vincennes and Noisy-le-Grand Mont d'Est for the full 16 days of works. Meanwhile, Marne-la-Vallée Chessy, the station that serves the famous Parc Disneyland Paris, is the terminus on this RER A branch. So how can you reach this station if service is suspended?

The journey won’t be easy. But the RATP announces the deployment of substitute buses between Vincennes and Noisy-le-Grand Mont d’Est. Commuters can notably opt for the omnibus shuttle circulating between Château de Vincennes (line 1 of the metro) and Noisy-le-Grand – Mont d’Est, with an estimated travel time of 55 minutes. Alternatively, choose the shuttle between Nogent-sur-Marne (RER A) and Noisy-le-Grand – Mont d’Est, a direct route with an estimated 40-minute journey. Once in Noisy-le-Grand Mont d'Est, it will then be possible to reach Marne-la-Vallée Chessy again by boarding the RER A. Stay tuned for the schedules of these shuttles set up for the occasion.
