Hi arc,

I posted in my thread as well....you can also check out the transit authority website (in english) here:

They have a pretty cool feature where you put in your flight info and it'll tell you when you should arrive by and what trains will help you. I did say it's the S8 (s-bahn) but you can also get some RB trains with different numbers.
