New York City Subway

The New York City Subway system is the largest in the United States and one of the largest in the world. It has roughly 450 stations and 26 different train services. Truthfully, it's a bit confusing, not only inside but also outside; since most stations can be entered from each sidewalk and lead to a different side. That is, one side of the street will be an uptown direction and the other runs down town, but inside there could be a platform change. In others, there is an interior change. Regular fares are about $2, but are only available if you go often. You can get 6 for the price of 5, but you can only use four straight.
