I'm impressed! The subway's a big system.. I can imagine some stations everyone's been to, and some are on a "Why Would Anyone Go THERE?" list. Do you have a favorite, or a candidate for a hidden gem?
What, I can only name one?
The subway is very large and diverse and there is a lot of interesting infrastructure out there.
- 190th Street on the A and 174th-175th Streets on the B/D share an interesting quirk: both are completely underground stations where you can get off the train and go physically down to get to the street!
- Wilson Avenue on the L is underground in one direction and above ground in the other.
- Broad Channel on the A is in the middle of a swamp.
- Ditmars Boulevard on the N/Q is elevated above the street but also directly below another elevated structure: the approach to the Hell Gate Bridge
- Mets-Willets Point on the 7 has a lot of gates that open and close and pedestrian traffic flows in and out of the station completely differently depending on if there's an event at one of the local stadiums or not.
- 168th Street and 181st Street on the 1 are among the deepest stations in the system and have beautiful barrel vaulted ceilings. Unfortunately, they've been covered with scaffolding since some masonry collapsed onto the tracks at 181st a few years ago.
- Essex Street on the J/M/Z is next to an abandoned underground trolley terminal which is visible from the eastern half of the outbound platform.
- there is a completely abandoned City Hall station at the south end of the 6 train, which you can see if you stay on a downtown train past the end of the line at Brooklyn Bridge (the track makes a loop from downtown, through City Hall, back to uptown).
Really, there is a lot to see!
