Bit outside my usual UAP stuff but this caught my eye. I've been down a rabbit hole on this lately and yeah, the clustering around old rail corridors is hard to ignore once you start mapping the reports.
My theory, for what it's worth - old rail lines follow natural contours, valleys, ridge lines, that sort of thing. So they'd naturally overlap with whatever habitat these things supposedly use. Could be correlation not causation basically.
But then some of the older lines have been abandoned for decades and are basically dense woodland corridors now. Perfect cover if something large wanted to move around without being seen. Seen a few BFRO-adjacent reports from the US rust belt that specifically mention the treelines along disused tracks.
Anyone actually done a proper map overlay with the sighting databases? Would be interesting to see if theres a statistically significant pattern or if we're just connecting dots that aren't really there.
