Tracks of the New York City Subway

The best source of information on the New York City subway system.

Joe Brennan's Abandoned Stations pages. Likely the most comprehensive listing of abandoned Subway stations, and a constant reference source for the book.

Joe Korman's Web site, in which many interesting and fascingating bits of Subway Lore are found. Joe was kind enough to provide the Chaining Codes found in the book, and that information is presented through this site.
