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.
PS: If you know where this is, don’t comment. To the guy that called us dickheads for not approving your tell all comment, sorry but not sorry. Instead of proving your knowledge you just proved you’re an insolent little derp that can’t keep his mouth shut.
