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

Named Éole, for East-West Express Link, the RER E began operating in 1999 and is now the smallest line on the Île-de-France regional express network, covering a 52-km route. It has 23 stops and crosses several departments in the Île-de-France region as well as Paris: Val-de-Marne, Seine-Saint-Denis and Seine-et-Marne.

Starting from Gare Saint-Lazare, the RER E has two other stations in Paris: Magenta (where Gare du Nord is located) and Rosa-Parks in the 19th arrondissement of the capital. It then heads out to the suburbs, serving, among other places, the Rosny 2 regional shopping center in Rosny-Sous-Bois, in Seine-Saint-Denis. In terms of connections, the RER E links up with several metro lines. From the RER E, on the Paris section, passengers can connect to metro lines 2, 3, 4, 5, 7, 9, 12, 13 and 14, as well as the RER A, B and D.
