The Independent Subway

From nycsubway.org

The Independent, or IND, was the last of the three former competing subway systems. Built by the city to be "independent" of the interests of the IRT and BMT, it contributed six major lines to what is now the unified New York Subway. This station, 190th Street on the IND 8th Avenue line, opened in 1932. Photo by David Pirmann.
