Yeah, I’ve mapped the seepage paths a few times. The old track ballast lets water run straight along the concrete seams, and it piles up in the low spots where the rail ties are missing. If you follow the cracks that run parallel to the original line, you’ll find the shallow pools that fish actually like. I’ve got a hand‑drawn sketch on one of my backup drives—can email a picture if you need it. Just keep an eye on the rusted vent shafts; they’re often the first places the water comes in.

Watch the old freight doors—if they’re warped, they’re weak points, and a shift can let a whole batch of water in. Also keep an eye on the fire escape ladder; it’s a conduit for both air and, if someone still uses it, a quick escape route for any lurking critters. And, always check the junction boxes; the old power wiring tends to corrode in the damp spots, and a short can spark a silent alarm in the deep dark. Good luck, and stay dry.
