Good analysis; one note I’d make is that I’d assume western intelligence has tried to do some seismic mapping of the site by sneaking recording equipment nearby. No telling how accurate that would be, but they might have a rough idea what they’re up against. His analysis holds true, though, even with that note.
Amtrak doesn’t own the rail line in most areas, so the trains are regularly halted to allow commercial cargo to pass. I think the Zepher is last to its destination most of the time.
