As we’ve mentioned before, New York City’s original pneumatic tube mail network has a fairly interesting history, transporting mail–and once, even a cat–throughout the city from 1897 to 1953. There are some remnants of the 27-mile postal system (which linked 23 post offices) still viewable to the intrepid, but images like this early-twentieth-century map reveal the extent of the unique delivery system and the promise it once held, as well as how some destinations on the network have evolved.

It’s hard to imagine NYC without its current sewer systems, but before the advent of remotely monitored sewer systems, the city not only directly monitored its sewers, but it was also considered perfectly acceptable to dump raw waste into the ocean before the Ocean Dumping Act was enforced in 1991.

Even with these modern-day waste issues, however, the city sewer system has improved a great deal since the turn of the 20th century. Before modern sewage, New York once had piles of trash lined up on the streets, creating a strong fecal odor composed of horse manure and urine.

Untapped Cities Twitter follower, @justinr592, submitted this photograph he snapped of a pneumatic tube system from his office on 86th Street and Lexington Avenue. He also tweeted, “From the pneumatic tube map you have up, it seems like the Gracie [Mansion] area. Hmm…”

We’ve been so pleased with the fact that the Hyperloop plan has brought our favorite forgotten technology to light: the pneumatic tube system in NYC. Gizmodo and Curbed gave Untapped some great shoutouts to our pieces on the tube system and where to find the remnants today. The pneumatic tube system was used for a covert, secret construction of a subway in 1870 by fantastical inventor Alfred Ely Beach. It worked, but was shut down by Boss Tweed three years later. Pneumatic technology is also used in the New York Public Library stacks and for trash under Roosevelt Island.

Earlier this year, we looked into the pneumatic tube system that used to carry mail between post offices in New York City. The system was 27 miles long and connected 23 post offices, and included tubes over the Brooklyn Bridge to connect the General Post Office in Brooklyn to Church Street in Manhattan. The USPS stopped using the system fully in 1953. Last week, Untapped reader @Charlesinist asked us “Anyone know where I can see remnants of the old US mail pneumatic tubes in NYC?”

Today, we’ll show you where some remnants of the system are and where pneumatic tubes are still used in the city.

Untapped Cities writer Brian Orce sent us this photo of a quirky lighthouse atop a building in the Bronx, which he noticed while stuck in traffic along the Major Deegan Expressway. How did a beacon of the sea come to guide the commuters of New York City?

The building at 945 Summit Avenue was once the headquarters of H.W. Wilson, a publishing company, known for its Readers Guide to Periodical Literature. The lighthouse was part of the company logo, symbolizing the mission of H.W. Wilson: “To give guidance to those seeking their way through the maze of books and periodicals, without which they would be lost.”

The interior of the building still made use of pneumatic tubes, the once ubiquitous means of delivering mail in New York City, but is unclear if those details were kept after its conversion into the headquarters of Tuck-it-Away storage, who painted the lighthouse orange. H.W. Wilson merged into EBSCO Publishing in 2012, while Tuck-it-Away lost the famous eminent domain battle with Columbia University in West Harlem, forcing the move to the Bronx. The Bronx Times reports that Tuck-it-Away is considering a business incubator in the space as well.
