This is quite possibly the most unknown, undocumented section of subway tunnel currently available.
What we have here is a provisional tunnel, built with the intent of connecting it to a whole new subway route which unfortunately was never built.
It’s almost impossible to find, and for the moment we’re not going to give any real clues. Mysteries like this one keep people exploring. Not everything needs to be detailed online. The best finds are the ones you come across in person or are introduced to via peers (whose trust you’ve earned)
Indeed, we’d never have known about it if it wasn’t for the amazing persistence of some of the older cats out there. As I like to say, if we seem large sometimes, it’s because it’s on the shoulders of giants.

Angling for that shoe sponsorship…

Water gets through any hole down here…

Would be a good place to play with lights – there’s no light at all down here.
A Note on ‘Gatekeeping’
Most of the subway content on this site was written twenty years ago and purposely left with vague information. No one was seriously exploring subway tunnels at the time (literally, no one other than us).
These posts were literally designed to get people get out exploring, and to find places on their own, like we did before the open-book test of the internet and social media even existed.
Fast forward twenty five years (2026 present day) and there are hundreds (thousands?) of people exploring in NYC. ALL of this information is now online elsewhere. That wouldn’t have happened if the mystery of posts like this one didn’t get more people exploring. NYC wouldn’t have so many amazing explorers today finding things we never did if it wasn’t for that mindset.
It’s not gatekeeping, it’s inspiration. And if you’re too lazy to be bothered doing it then go back to watching TV.
The mindset is simple: Go. Find the doors, find the access points. Do you. And don’t ask for hand outs.
Congrats on finding the origin story, and if you figure out where this spot is, congrats on passing the open book test known as the internet. Now strap on some boots and find something no one has seen before.
