CJACK - Detecting a derailment that doesn't trip the breaker is a challenge. How to differentiate this from a normal current load. It might have to be a dynamic check looking for a sudden change in current? Maybe use a video camera with derailment recognition software.
I was thinking maybe a short piece of rail outside each of the two outside rails for the wheel that's off the outside rail to bump against and trigger the shutdown...
