The Old City Hall Subway Stop
General info: This stop closed in 1945 due to its inability to be modernized, along with the low amount of traffic it received. Tours are sometimes available. There's actually a number of other closed stops throughout the city. You can catch a glimpse of the station as the 6 train passes the last stop and loops around.
Accessibility: Closed to the public.
The Freedom Tunnel, Riverside Park Tunnel
General info: The Freedom Tunnel was a once abandoned train tunnel running by Riverside Park that housed a homeless shanty town. Today it is used by Amtrak, but it is one of the prime areas for urban exploration and graffiti work in the city. To get there, follow this guide.
Accessibility: This is open to the public.
Warning: This is still an active train track.
