RER E: service disrupted or interrupted, real-time updates on the line

Named Éole for the East–West Liaison Express, the RER E has been in service since 1999 and today stands as the shortest line in the Île-de-France regional express network, stretching 52km. It features 23 stops and crosses several Île-de-France departments besides Paris: the Val-de-Marne, the Seine-Saint-Denis, and the Seine-et-Marne.

Starting from the Gare Saint-Lazare, the RER E has two other Paris stops, Magenta (where the Gare du Nord is located) and Rosa-Parks in the 19th arrondissement of the capital. It then heads into the suburbs, serving notably the regional shopping center Rosny 2 , located in Rosny-Sous-Bois in Seine-Saint-Denis. In terms of connections, the RER E connects to several metro lines. From the RER E, on the Parisian segment, one can reach lines 2, 3, 4, 5, 7, 9, 12, 13 and 14 of the metro, as well as the RER A, B and D.
