Travel Information about France and Paris

(GMT)02 DEC 2016 G4CEQS:  Paris Metro vs. RER
Do you know the difference?
The Metro is a classic subway system: mostly underground, many stops, frequent service, short line distances, serving the urban city centre, non-scheduled train timings.
The RER (Réseau Express Régional) is a commuter train system that covers much of the greater metropolitan area of Paris (Ile-de-France ), much further out than that covered by the Metro, including specifically both Paris Airports: Paris Roissy-Charles de Gaulle (CDG) and Paris-Orly (ORY) , Disneyland® Paris, and Chateau Versailles.
The confusing part is that the RER traverses central Paris with a handful of stations, acting like an express Metro system with fewer stops, larger trains and faster movement. Paris fare zones apply to the RER train system, unlike the Metro and there are six of them. Using a Metro ticket, the Ticket t+, is permitted on the RER, but only to the limits of Zone 1, the true center of Paris, bordered by the ring road surrounding it, the Boulevard Periphérique.
