Seoul Station

Following the path.

Taking the escalator.

Another look at the surfaces.

Another hole in the wall.

Going further than I had before, I reached this plunge down a significant distance.

This was at the bottom. I'd like to say elevator shaft, but those doors are pretty small.

At the bottom, I found this opening into a much larger cavern, where there was a lot of noise from dripping water.

Here's the actual GTX tunnel.

And looking in the other direction. Not sure how this layout works.

Time to start heading up.

This was most of the way up.

That cabin at the top is my exit point.

Okay, I'll be safe, banner.

The last push up to the top.
