High Quality Content by WIKIPEDIA articles! The RER station Val de Fontenay is a station in the Paris suburb Fontenay-sous-Bois and is an important correspondence between the lines A and E. The station is named for a neighborhood of Fontenay-sous-Bois. It is served by both line A (branch A4) and line E (branch E4). Starting 4 February 2008 RATP changed the number of trains running on the RER A. In off-peak hours, there are now 12 trains per hour instead of 6. Of those 12 trains going to Marne-la-Vallée, 6 are direct between Val de Fontenay and Noisy-le-Grand (the stations of Neuilly-Plaisance and Bry-sur-Marne are skipped).
