The OSE site does confirm the existence of that connection, though. I would, however, be a bit concerned about a connection of 5 minutes. You never know if trains will wait for each other if delayed (which they will be

)
Anyway, like you mentioned, perhaps driving is a better way to do this...
I guess that depends on how confident you would be with driving in Greece - in particular the Athenian end of your journey. Once out of the city you'll be out of most of the lunacy - just don't forget the golden rules in Greece: Expect the unexpected and however many lanes there are on a road, expect there to be one column of cars using it...
Would you say Meteora is worth all the time and effort to get to? I've heard great things about it and really wanted to see if I can fit it into my itinerary.
Oh yes

I've been itching to get up there since meeting my wife (Greek) 12 years ago. We finally made it there last Easter. Well worth the journey - absolutely breathtaking scenery... Visit as many of the monasteries/convents as you can - each is uniquely different and opens up different vistas.
Hope this helps,
Mark.
