Date Closed: 1958
The Sedgwick Ave station opened in 1918 as an extension of the 9th Ave El, New York City's first elevated railway famous for its 90-degree "Suicide Curve" at 110th St. Located near the Harlem River in the Bronx, the station was built as a point of transfer from the El to Metro-North predecessor, the New York Central Railroad. It was also an important stop along the shuttle between the old Polo Grounds and Yankee Stadium, a train service beloved by baseball fans -- which gave rise to the term "Subway Series." The shuttle was discontinued in 1958 when the New York Giants jumped ship to San Francisco and the Sedgwick Ave station became obsolete. Its elevated steel structure was removed, but the platform and tunnel remain. Take the 4, B, or D train to 161 St, and walk across the footbridge over Sedgwick Ave and the Major Deegan Expressway. There you'll be able to make out the ground-level portions of the old station hiding under the highway.

Most of the city’s abandoned subway stations sport at least a minor air of mystery, but this one’s very existence has been hotly debated for years. “The station cannot be found on any map, however, nor can it be reached by any train,” the New York Times wrote in 2003. “If it exists, in fact, it is nothing more than a dark four-track IND subway station with blue tiles, on the A line near Ozone Park, Queens.” The station is rumored to be part of a plan to extend the A line to 229th St in the Cambria Heights area of Queens and to lie behind a tunnel that was sealed off in 1952 -- meaning that even if it does exist, it’s near-impossible to access. There is next to no visual documentation of the station, though the daredevil urban photographer known as Dark Cyanide recently snapped some pics of a concrete wall he believes it’s hiding behind.
