Once you have bought your ticket for the RER Line B trains from Paris-Charles de Gaulle Airport to central Paris, look for the electric signboard that shows the trains:

Mission is the four-letter code identifying the train (more...). (The codes for the 12:18 and 12:33 trains are both PEPE. The codes for the 12:25 and 12:40 departures have not yet been posted.)

Voie is the number of the track from which it departs.

The lines of dots show the stations at which each train stops (white means it stops; black means it doesn't stop). So the trains departing at 12:18 and 12:33 are locals, stopping at every station. The trains departing at 12:25 and 12:40 are express, making only two stops before reaching central Paris (Gare du Nord).

It's good to remember that you can board any RER train at CDG Airport's Aérogare 2 and it will take you to central Paris. But you'll get there faster and more comfortably, with less chance of crowding, on a train that makes fewer stops.

Having chosen your train, look for the doors marked:

PARIS PAR TRAIN
PARIS BY TRAIN
PARIS VIA TRENO

(See the photo on the right—>).

(Don't go to the TGV tracks or you may end up in some other part of France, or even in Brussels!)

Descend by escalator, stairs or elevator to the tracks, check the track number (Voie) and the four-letter code for your train, check the clock for the departure time, board your train and ride. Many RER train cars have baggage compartments for bicycles at one end. If you have lots of luggage, you can put it in the bicycle compartment and ride in seats nearby. Look for this logo to find the bicycle compartment —>

The RER Line B train stations in central Paris are:

—Gare du Nord (called PARIS NORD on the signs in the RER station at that stop), a major SNCF intercity train station (more...).

—Châtelet Les Halles, on the Right Bank near the Louvre, Hôtel de Ville and Le Marais.

—St-Michel Notre Dame, the very heart of Paris on the Left Bank near Île de la Cité, Notre Dame, the Latin Quarter and the Sorbonne.

—Luxembourg, near the Jardin du Luxembourg, Église de St-Sulpice and Panthéon in the Latin Quarter.

—Denfert Rochereau, intersection of major boulevards in the southern part of Paris.

If your hotel or apartment is in the center of Paris, you'll probably want Châtelet Les Halles or St-Michel Notre Dame, but from any of these stations you can transfer to the Métro (no additional fare) or a taxi (minimum fare 5.40€) to reach your final destination.

Remember: All RER trains from CDG Airport go to central Paris, and hold on to your ticket. You'll need it to exit the station in central Paris.
