Lesson learned in a subway tunnel - Thread - Urban Exploration Resource

Several years earlier, I was able to get into a subway tunnel under construction in the very early stages. My original entrances were sealed as construction progressed.

Then I was contacted by a new guy here about subway tunnel access. I was guarded about it of course, but it inspired me to trace the subway route to see if I could find any entrances. I did, some pretty disturbingly wide-open ones.

My first visit last week, here's what I saw:

1. Subway station entrance under construction.

2. The subway tunnel itself was looking pretty complete.

3. I'd never seen a platform like this in the middle.

4. Looking back toward the station.

5. In the other direction, the tunnel curves sharply downward.

I met up with the new guy, as well as two more experienced friends, and we went back in.

7. But this time, there was a very obvious warning sign blocking our way. It's so obvious that there's no chance I missed it last time.

8. Clearly marked, if you understand Korean, which the new guy did not.

9. Not a very big station.

10. This is what it looked like down on the tracks. Most existing subways here get their electricity from an overhead wire, so I have no clue what a third rail looks like. I just didn't touch anything, even when I went out the previous day into the tunnel -- which I wouldn't have done if I'd seen such urgent warnings.

11. Anyway, more fun to be had.

12.

13.

14.

15. We all made it out alive.

The whole thing has gotten me to commit further to preventing information leaks and being careful to vet newcomers, at a time when I've been getting more requests and facing more challenges to stay quiet. This guy seemed to have his head together, but who knows about the next one.
