Overview
NOTE - Change of Identity messages are only sent for freight trains.
One or more Change of Identity messages may be sent for a freight train, after activation, where the class of the train is to change. This will happen if the train will run without wagons (i.e. a Class 6 service runs as a Class 0), or if the train is carrying a wagon with a defect and must run at a slower speed.
