The passenger areas are still largely the same layout, you just have to imagine what used to be over your head.
If you walk underneath where the trains are, there are some remnants of the original Penn Station, a large grandfather clock, some old signs stating where the original trains used to dock and something else, I am forgetting at the moment.
In what spurred on the early historic preservation movement, the original Penn Station (as shown in the photo) was torn down in the 1960s for a really ugly Madison Square Garden.
still waiting to be rescued by from Hurricane Katrina.
Notice the horsecart in center of photo, there are buildings what looks like below street level. Why did they do that? I'd hate to live in one of those buildings below street level.

I'd hazard a guess that they were a crew working on the roof and were taking a lunch break or something at the time the pciture was taken.

Are those people sitting on the roof?
Such a beautiful building.
