context_page_description: RER E is one of the five lines in the Réseau Express Régional, a hybrid suburban commuter/rapid transit system serving Paris, France and its suburbs. The 52.3 km RER E line travels between Paris and eastern suburbs, with all trains serving the stations in central Paris, before branching out towards the ends of the line.
  The line runs from the western terminus Haussmann–Saint-Lazare to the eastern termini Chelles–Gournay and Tournan. It is operated by SNCF.
  Originally referred to as the Est Ouest Liaison Express or EOLE, RER E is the newest line in the system opening in 1999, with the extension in 2003, and further extensions to the west currently under construction.
