Subways Of New York

My grandfather worked in the New York Undergrounds... He worked for the telephone company and on many occasions while in New York he would take a short cut.

Through a locked door, into a dark hallway and a few minutes later... destination.  His knowledge of the tunnels, passages, subways, and all the other features of the New York underground was amazing.

New York Subways

The New York City Subway is a rapid transit system owned by the City of New York and leased to the New York City Transit Authority, an affiliate of the Metropolitan Transportation Authority as MTA New York City Transit. Together with its bus operations, it is the most extensive public transportation system in the world, with 468 reported passenger stations, (or 422 if stations connected by transfers are counted as one). 656 miles (1056 km) of revenue track, and a total of 842 miles (1355 km) including non-revenue trackage. The subway is also notable for being among the few rapid transit systems in the world to run 24 hours a day, 365 days a year. Among the ten busiest systems in the world in terms of annual passenger traffic, it is the only one to hold such a distinction, setting it apart from cities such as London, Paris, Tokyo, and Moscow.

Though it is known as "the subway", implying underground operations, about 40% of the system runs on above-ground right-of-way (the system is almost entirely underground in Manhattan, as well as portions in the other boroughs), including steel or cast iron elevated structures, concrete viaducts, embankments, open cuts and surface routes. All of these construction methods are completely grade-separated from road and pedestrian crossings, and most crossings of two subway tracks are grade-separated with flying junctions.
