Anyone that can confirm?
Sorry for the delay in responding - I had to get some drawings from the vault and scan them.
I'm not going to confirm or deny the location of any operable access points. If I post current information, I get complaints due to security concerns. However, as a result of an agreement about that, I can
post anything that's in a historical document, no matter how rare.
With that in mind, I present some scans of parts of Haskin's original drawings, which were loaned to Burr for his 1885 book, Tunneling Under the Hudson River
You can click on each of those for a larger picture (warning: 2048-pixel-wide JPEGs).
There aren't any street names on that part of those drawings, but the pier locations are shown in detail.
By the way, for a shaft you can see, walk south along the waterfront from the Exchange Place station. Just at the waterline (depending on tide), you'll see a large round iron cylinder sticking out of the shore, with a concrete cap on it. You're actually looking at the outside of a vertical shaft formed with the same type of ring segments used for the downtown tunnels (except smaller). That was where they removed all of the material excavated to build the Exchange Place station. Since the Pennsylvania already had a terminal on top, they couldn't just dig down right there. If you look at the wall of the Exchange Place station (WTC-bound platform, near the east end, on the far wall) you'll see a pair of stainless steel doors. That's the other end of that shaft (it runs roughly horizontal until it meets the vertical shaft outside).
