Right so this is something I've been chewing on for a while. The rail connection makes a lot of sense to me from a ley line perspective - old Victorian rail routes often followed pre-existing trackways and ancient paths, basically the same corridors people and animals have moved through for centuries.
I've been mapping reported Dogman sightings in the north of England and there's a noticeable clustering near disused lines, particularly around embankments and old cuttings. Those spaces are interesting because they're liminal in a very literal sense - they're corridors that don't quite belong to the surrounding landscape, kind of carved out of it.
My theory is its less about the rail lines themselves and more about what the railways were built on top of. Would love to know if anyone else has done any mapping work on this. Has anyone cross-referenced sighting locations with old Ordnance Survey maps to check for pre-railway trackways underneath?
