The Brooklyn Eagle and the Associated Press ran a story today about how the NYPD is protecting the subway system from terrorists. It mentions a super-secret subway exit disguised as a brownstone in Brooklyn Heights. They don’t reveal the location but the piece claims many Heights residents know where this mysterious exit is located.
Brooklyn Eagle: Brooklyn Heights, in fact, is home to many secret emergency stairways leading to track lines that climb from under the East River to stations in Brooklyn. These emergency exits are sealed, unmarked and rarely, if ever used.
Since Brooklyn Heights and Downtown Brooklyn are where many lines converge before fanning out to the rest of the borough.
Located in the tunnel just east of the river, the exit disguised as a brownstone leads to a grimy-lit set of metal stairs that ascend past utility boxes and ventilation shafts into a windowless room with a door. If you opened the door, you would find yourself on a stoop, which is just part of the façade.
