Perfectly safe, as far as I am concerned.

Some more info on the RER B:

The Express trains from CDG are generally listed as KROL (This is the 4-letter "name" of the train). Starts around 9 a.m.

The trains to CDG start with the letter E -- EKLI trains are expresses (as well as a few others). Earliest exprees leaves Chatalet around 9:30 a.m.

This is a good site (Paris By Train) for details:

Here is the schedule to CDG from the Paris By Train site:

ooops...

That link I just gave is to an older schedule to CDG, but I have one from Dec 2008 and it's not much different, so it probably hasn't changed much since then.

One thing I don't recall anyone else mentioning on this thread concerning the RER *to* CDG is this -- the RER B line has TWO terminal points! (Actually four, as the south end also has two terminal points.)

B3 terminates at CDG; B5 terminates at Mitry-Claye. If you realize somehow that you've boarded the wrong one before the Aulnay sous-Bois stop, you can change to the right one; otherwise you'll end up in the wrong place.

Reading the destination boards can be rather confusing until you get the hang of it. Each train has the terminal station indicated on the front of the first car -- but unless you see the train entering the station, there is no indication of where it's headed other than that destination board overhead.

bookmarking, thanks.

I don't think reading the destination boards is all that confusing. If the destination is not "Aéroport Charles de Gaulle" and you want to go to the airport DO NOT get on that train!

astute advice, kerouac! I've never found the destination boards to be a problem...guess I followed kerouac's advice.

Excellent, excellent, MOST excellent thread! Too bad Fodor's doesn't have some way to "pin" or "sticky" detailed instructional threads such as this one.

Bookmarking, thank you for the helpful info!

I appreciate your sharing knowledge of Paris with us. I always arrive at Terminal 2E (Delta). I pick up my luggage at the baggage caroussel and take the Roissybus in. I would like to renew my Navigo 1-5 without having to walk to the RER station and then back to 2E. Questions: Is there a place to renew the Navigo near the baggage caroussel for 2E? If I must go to the RER station to renew Navigo, is there a Roissybus station near there? Thanks, Kerouac, for all your past help.

I'm pretty sure that you would have to go to an RATP or SNCF desk to renew your Navigo, but maybe not -- and that's why the general airport information counters exist.

Frankly, 2E and the RER station are not very far apart, though.

I have a question. Are the pay phones at the CDG airport like the ones in the FRA airport and they take Euros so I can call to the States. (It has like a pink box on the top with a "T"). I have a ATT prepaid phone card to. Can I just that?

Jennifer, might be best to Start a New Topic with this question instead of replying to an old thread from last year that has nothing to do with your new question.

The phones I found in CDG do not take coins. I had to buy a card to make calls.

I think there are a few coin phones lurking in obscure corners, unless they were finally removed due to lack of use.
