This is related to the nomenclature thread I started today: In real yards, do they use signs to indicate track names/numbers/IDs? What I'm looking for is some sort of example of a sign to show which track is which. Ya know, like at an airport, there are these white-on-black signs pointing the way to runway 18R or something. I want to add some small signs to my layout, so that operators can see which track is which. Is there a prototype for this?
