A Primitive Hyperloop: New York City's First Subway
Abandoned/Secret New York Subway Station - City Hall Station
We Smuggled Ourselves Into New York's Abandoned City Hall Station
The Beach Pneumatic Transit was the first attempt to build an underground public transit system in New York City. It was developed by Alfred Ely Beach in 1869 as a demonstration subway line running on pneumatic power. As the subway line had one stop and a one-car shuttle going back and forth, it was not a regular mode of transport. It lasted from 1870 until 1873.
