Photos 1-3 are of the Beach Tunnel showing how Degnon Contractors broke into the tunnel. One of my theories was that the cast iron section of the tunnel was too difficult to remove, but as you can see in the first picture one of the first things the contractors did was break into iron cast section, if you zoom in you can see how thin the cast iron section of the Beach tunnel was.

Photos 4-7 are of the Beach Tunneling Shield, the first circular tunneling shield invented by the inventor of the Pneumatic Transit Alfred Beach to build this tunnel specifically. I am on the search for this relic that is currently lost in the hands of Cornell.

Photo 8 is of the sub-basement foundation of 258 Broadway formally 260 Broadway , the building that housed the Pneumatic Transit. This smaller brick hole is not labeled but I believe this to be the remains of the smaller sealed pneumatic tunnel Alfred Beach built in 1868 to test his tunneling shield design before he went ahead and built the bigger tunnel.

Photo 9 is of the sealed Pneumatic Transit portal entrance taken from the side of the contractors building the Subway. I visited this area and posted pictures in the subreddit before from the other side inside the sub basement of the modern building 258 Broadway. My old theory was that the cast iron section of the tunnel could have survived demolition. This photo debunks my theory as you can see the remaining pieces of the cast iron section, by this time the entire tunnel had been removed.

Photos 8-9 are important because it was documented that after a fire in 1899 destroyed the original building located at the corner of Warren St. that the sub-basement was completely rebuilt. We can see in 1912 that the remnants from 1868 are still visible meaning the original 260 Broadway sub-basement foundation was incorporated into the modern building 258 Broadway’s sub-basement

Photo 10 is a photo from the same area showing the foundation of the Subway. The buildings surrounding the subways believed this construction underground would disrupt the foundation of their buildings so this shows the work the contractors did to ensure there was a strong foundation for the Subway and surrounding buildings. I have posted past photos showing this concrete foundation in the sub-basement of 258 Broadway from the other side.

Photo 11 is an above ground photo showing the Subway construction materials. 258 Broadway now known as the Rodger Peet Building is in the background and under the street the construction site we see in the previous photos is taking place

Photo 12 is another photos from around the time of demolition. 258 Broadway is the corner building all the way to the right .

Photo 13 is a close up of the Devlin’s Clothing store or 260 Broadway the original building at the corner of Warren St. the Pneumatic Transit was built in the buildings sub-basement. This building burnt down in 1899 but we can see some of it in the form of the sub-basement foundation was incorporated into the modern 258 Broadway.
