Subject: Re: Paris: Train from CDG to Gare du Nord?
Hello,

CDG1 and CDG2 are two different stations on the same RER line. All trains stops at both and CDG2 is the end of the line. Be aware that getting to/from CDG2 station requires either a long walk or going outside the terminal and catching the free shuttle bus. There are plenty of signs though.
