✉️ The Lost Pneumatic Tube System at the NYSE
Long before fiber optics and wireless networks, bursts of compressed air kept Wall Street moving.

So much was happening around the Grand Central Parade of Trains yesterday. Families reveled in “Kid Junction” at Vanderbilt Hall, historic railcars were on display on the tracks in Grand Central, 1950s and 60s vintage trains were running along the S train, and Untapped Cities had its “Secrets of Grand Central” tour which concluded with cocktails at The Campbell Apartment.
We rode the vintage trains twice, snapping photographs of the fun, vintage ads. Did you catch a ride on the trains? Submit to our Untapped Photo Pool by hashtagging #untappedcities on Instagram and Twitter!
