CDG to Paris Auber
 

Does the RER A line run from CDG to Paris? I need to get to the Auber station which is served by the A line I believe but the CDG to Paris websites that I see only refer to the B line from CDG to Paris which doesn't stop at Auber.

there are frequent direct RER trains from CDG 1 and CDG 2 RER stations to Chatelet-les-Halles RER station and change there for RER a to Auber - being sure you follow signs that indication 'direction Auber' on the list of stations for that RER A entrance. Should take about 45 mins - at CDG be sure to board trains that say 'Paris sans Arret jusqu'a Gare du Nord or you may get on the much slower stopping trains that though they may leave earlier may arrive later.

At CDG RER stations look at the overhead signs on the platforms that will indicate exactly which Paris stations it will stop at (lights lit) - sometimes you may find it quicker to take an RER train to Gare du Nord then on the same platform or adjoining one change RER trains to get to Chatelet-les-Halles, where you follow transfer signs for 'RER A in a circle'.

Keep your ticket until you are out of the system as you may need it to not only put thru turnstiles when changing RER trains and to turn turnstiles to exit the system at Auber.

Super simple to transfer at Châtelet-Les Halles. Auber is only one RER stop away from there.

kerouac - by simple do you mean from an opposite platfform to your arriving train like I seem to recall? No long trek thru tunnels, etc.

???

merci

No trek at all.

However, thinking more about this, why not just take the Roissybus? It is direct to Auber/Opéra.

Is there room for luggage on the Roissy Bus?

Yes, it is designed for people taking planes and getting off them with all of the usual stuff.

And concerning the connection in Chatelet, the transfer is not as simple as remaining on the same platform. You have to go up to and cross the (very) wide connection zone to get to the other platform.

Thanks again.

"Very wide connection zone" is an exaggeration. When you arrive at Châtelet-Les Halles, you can see all of the parallel tracks. In the event of needing to change platforms, that means, wow, you might have to cross over two sets of train tracks, with escalators everywhere. This takes less than 60 seconds.

Seems like as seemless change at Chatelete as possible. I do know that at Chatlelet there are some changes to trains right across the platofrm but I think these must be trains like RER D perhaps or RER A trains going in the same direction as the train from CDG - you have to cross to the other side of the tracks like in any train station to catch trains going in the other direction.

The Rossiy bus is also easy to spot and board at CDG - at least in terminal 2 - at a sparesely used end of one appendage with the bus right out front - can take luggage carts to the bus itself.
