|Choosing an RER B Train to Paris|
|All RER Line B trains from Paris-Charles de Gaulle Airport go to central Paris, but some go more quickly than others. Here's how to choose a fast one.|
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. (See the list of central Paris stations below.) But you'll get there faster and more comfortably, with less chance of crowding, on a train that makes fewer stops.
Reading from left to right, first comes "RER"(for Réseau Express Régional), then "B" for Line B, then the 4-letter route code identifying the train's route and stops.
The fastest trains from CDG to central Paris have route codes beginning with KA (KALE, KALI, KAPE, KARE, etc.) or JA (JAMI, JANO). Other trains make more stops.
(For your return to CDG airport from central Paris, look for trains beginning with E. The express trains are ERIC, EROC, ERIO, ERSE, EDME OR EDDY.)
Then comes the departure time (in 24-hour time), the destination and perhaps some station information, and finally the track number (11 or 12).
The fastest trains, with codes beginning with KA or JA, depart Aérogare 2 and stop only at Aérogare 1 (Roissypôle) and the Parc des Expositions before entering central Paris at the Gare du Nord (Paris-Nord RER). Here's an example, a KARI train:
Other trains may be more crowded, and make a half-dozen other stops between Parc des Expositions and Paris Nord, making the trip slower.
If several trains are scheduled to depart within a few minutes of one another, I prefer to wait for the KA ot JA express train making fewer stops. The other stations are not particularly attractive, so there's no reason to take the slower train for the view. But if there are no KA or JA trains shown on the monitor, take any train.
Boarding Your Train
Having chosen your train, look for the doors marked:
PARIS PAR TRAIN
(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 some other European country!)
Insert your ticket in the turnstile, retrieve it when it pops up on top, keep it with you, and descend by stairs or elevator to the tracks.
Check the monitor for the track number (Voie) and the 4-letter route code for your train, check the clock for the departure time, board your train and ride.
RER Line B Central Paris Stations
Châtelet Les Halles
On the Right Bank of the River Seine in the very center of Paris near the Louvre, Hôtel de Ville and Le Marais, this station is the heart of the Paris Métro system. It's the largest Metro station in Europe—vast and confusing.
St-Michel Notre Dame
This intersection of major boulevards in the southern part of Paris is an important transport nexus, with connections to Paris-Orly Airport.
Which Station to Choose
If your hotel or apartment is in the center of Paris, you'll probably want Châtelet Les Halles, St-Michel Notre Dame, but from any of these stations you can transfer to the Métro or a taxi (minimum fare 7€) to reach your final destination.
