The Cincinnati Subway is the largest abandoned rapid transit system in the United States, a network of tunnels and ghost stations stretching over two miles under the Queen City. Construction began in 1920 and stopped in 1927. No track was ever laid. No train ever ran. The bonds were finally paid off in 1966, at a total cost of $13,019,982.45, for a subway that carried exactly zero passengers. Most Cincinnatians today have no idea it exists.

Cincinnati Subway: Ghost Engineering

Photo credit Jonathan Warren, CC BY-SA 3.0. What makes the Cincinnati Subway haunting is how ready it was. The double-tracked tunnels run north and south, each half a generous width and height, separated by a concrete wall with openings for cross-passage. The curves are banked to accommodate trains at speed, with outside s...
