What is this indication
Today on Green Line of Athens Metro at Kiffisia Station I noticed this in Vehicle Indication:
And I was wandering what the D8L19A means. It is shown when the rail starts a new route on the Green line just after the operator starts the locomotive. I have no Idea what system is used or what model the Green Line uses but it is rather old.
Please keep in mind that in Kifisia station is the Begining of the line.
