I uncovered NYC's hidden mail tubes 📬

Beneath the streets of New York City lies a 27-mile pneumatic mail network that once transported 100,000 letters a day using air pressure. Operational from 1897 to 1953, this system shot steel canisters through underground tubes at speeds of 35 miles per hour, linking 23 post offices across Manhattan and Brooklyn. In this episode, we explore the rise and fall of New York’s pneumatic mail system, discussing its innovative features, ceremonial cat launches, same-day Wall Street contracts, disastrous tube explosions, and sandwich delivery mishaps. We also examine what remnants of this once-thriving system still exist today. #PneumaticMail #NewYorkHistory #UrbanDecay Learn more about your ad choices. Visit megaphone.fm/adchoices
