I've just been looking into that.

I have some RI triggers on it but mainly restrictions on the deletion of other tables' recs for which the Infobase record has an FK (such as look-up values), and an Infobase rec can't be created unless there is a parent Route rec.

But none that should be fired if this field changes.

However, I'm checking on that now in debug
