Abandoned PATCO Franklin Square Station, Philadelphia

Not sure if this is the proper forum to post this question. Has anyone been down or know of someone who has been down into the abandoned PATCO Franklin Square Station, closed in 1979? I know that all the above-ground access points are sealed and that an underground concourse does not extend into the vicinity.

Any help would be appreciated.

I found this. Try googling PATCO Franklin Square Station.
