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.
