Not really my area but I'll bite. I'm mostly into hauntings and location-based weirdness so I don't follow train incidents closely, but the cell tower angle is interesting if true. Do you have any actual documentation of the outages - timestamps, carrier reports, anything like that? Because "went dark" could mean a lot of things and that detail matters quite a bit before drawing any conclusions.
I'll be honest I'm skeptical of the framing here. Correlation around major incidents gets picked up and amplified fast online and half the time it doesnt hold up when you actually dig into it. Not saying you're wrong, just that I'd want to see the evidence laid out properly before connecting dots.
What source are you working from on this?
