The gritty subterranean world of the subway is very much a part of the city. Like graffiti, the subway is not unique to New York but, it is an intrinsic part of the mystique that makes up the city of New York. The Subway is only underground in Manhattan, the trains pop-up and run on elevated tracks in the other four boroughs. The subway system is made up of 421 stations, 656 miles of revenue track and delivers over 1.5 billion rides a year. The Subway is a great and fast way to get around the city. It is a world in of itself, complete with art, entertainment, folklore, and mysteries. With millions of riders a day it is a busy place, people coming and going, bustling crowds become a faceless blur and the only constants are the station fixtures and posters. Crowds flow like waters of a river and pity the man going the wrong way. With so many people crowding their personal space, people tend to isolate themselves with diverted eye contact and perceived indifference. To visitors the subway seems intimidating and even a little scary, but with a little understanding it is easy to navigate. Come with me on a short excursion into a fascinating world waiting to be explored.
