Where is Punchestown ?!

[Wacom]

Hello.
Excuse my poor english.

I search "Punchestown" in Google Maps and I find a "mini-town" near Naas, here a screen capture:


Is this city? i can't find the circuit, where is it ?!
I search on "irish railway webpage" and i don't find a train to Naas or Punchestown, do you know if exist this train? or any way to arrive.

Thanks.
