Hi,
I am looking for some tips on how to reach Gare d' Austerlitz station from CDG by train. If I reach Notre Dame Station by RER B and switch to RER C to reach Austerlitz station, will this entire journey be covered by the single ticket purchased for RER B at CDG? Alternatively, if I were to take Metro to Austerlitz, which station should I get off RER B at? Will RER + Metro journey get covered by single RER ticket?
Thanks!
Raksha
