Change of Identity: Difference between revisions

Revision as of 14:50, 12 December 2018

Overview

One or more Change of Identity messages may be sent for a non-passenger (freight or engineering) 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.
