Zugschlusssignal

The Zugschlusssignal ("end of train signal") must be mounted at the end of the last car of a train. It is made from metal and there are usually two such markers at the end of the train. Station agents and operators along the tracks observe passing trains and note the complete passing once they see the Zugschlusssignal.

This marker is commonly used on freight trains, while passenger cars usually have lighted red end of train markers.

Wouldn't it be interesting to include proper placement of such signal in the operations scheme of our model railroads?
