During your New York City subway commute, you probably keep your headphones securely in place and your eyes glued to your phone or your nose buried in a book, but if you happen to glance out the windows into the dark subway tunnels, you might see something intriguing: The remains of an empty, abandoned subway station. These ghostly sites might make Batman fans think of the Bat Cave, or Oswald “Oz” Cobb’s secret base in HBO’s “The Penguin.” The robust New York City subway system is the pride of the city, but in Gotham, NYC’s dark mirror, the corrupt powers that be stopped funding their public transportation: TheGotham City Trolley. Both Batman and The Penguin have made use of these disused stations and tunnels as thematic lairs.
