It is very odd to me that states do this very thing for trucking, but apparently do not do it for rail.

They did. It was ignored. IIRC, the exact wording from dispatch was "If it's still alerting at the next sensor it's a problem."

I'm astonished that they treat those alarms like I treated the check-engine light as a poor kid who reasoned that the car seems to still be running fine.

Thanks for the clarification.
