The first link is located in the museum referenced in the second link. Within that museum you will find (hope I don't forget anybody) :
1 "N" scale club w/layout.
2 "HO" scale clubs with a really big layout.
1 Two rail "O" club w/layout.
1 Three rail "O" club w/layout.
I am a member of the 3rail club and it is a great running layout.

I was in Philadelphia for business last week and found this article. I didn't have the time to visit, but next time I will. They are in O and HO scales.
