What you drew there is a rough scratch paper version of a major Amtrak hub map
Take a look.
Specifically passenger /people mover lines.

Thos points are also near freight line hubs.
I'm curious now to see how many of those accidents happened on through way lines.

This is where people are getting the idea that it's unions working together to do this shit. Maybe not union sanctioned, but connected

Ride the Amtrak free and undocumented, go to hub, ride down railway, set up the spot, ride back, hop on next Amtrak.
