You can get some pretty sustained events since the current in the motor coils can stay charged longer than the make and break of sparking wheels in a derailment. This is rare but can happen when like the train derails but sparks a lot, rocks a bit, unshorts, shudders, shorts again , and repeat....  You just need some secondary clamp that works in forward bias mode.
