The Railroads have their “Bulls” and — trust me — if they don’t want the bodies found, the bodies won’t be found. Even working the “drag freight” you’d see crew aboard with open-carried sidearms. Saw one Conductor walking a flatcar with a Western style .45 revolver once. And, because the rails are federal territory, local PD don’t get to say jack crap.
The old Southern Pacific was pretty lax, but when the Union Pacific bought them out, all the old ‘boes moved on; UP Bulls don’t take no s@#+.
Or, at least, they didn’t used to; now it looks like the UP has lost its mojo. Sounds like the UP needs to staff up and mount up. Maybe with MP5’s.
Those trains DO go through some mighty empty places in the desert. Far from prying eyes along any roads.
