Been doing EVP work near the old Southern Pacific corridor outside Roseburg for about three years now and honestly the railroad correlation is something I've been sitting on for a while. The number of reported encounters that cluster around decommissioned rail lines is statistically hard to ignore if you actually map them out rather than just collecting individual reports like pokemon cards.
My working theory, and I stress theory, is that the cleared corridors and old right-of-way land just provides easy travel routes through terrain that would otherwise be dense and difficult. Nothing supernatural required. Animals use them, people use them, so why not something we haven't properly catalogued yet.
What I'd actually want to know from anyone posting sightings is whether the encounters were near active lines or abandoned ones, because that distinction matters quite a bit for ruling out mundane explanations. Also time of year. I've got maybe a dozen reports from this region I've cross referenced and theres a definite seasonal clustering I can't fully account for yet.
Anyone else actually doing systematic collection on this or is it mostly anecdotal?
