Prototype Railyard signs

[Santa Fe Jack]

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?

I've seen it, but heck if I'd remember where. They were white signs with black numbers on them, and an arrow pointing to the track. The switches were also set up the same, but they were black signs with white numbers & letters (I.E. A1, A2, B1, C1, ect).

Ah - yes, that's exactly what I'm after. I am imagining a little black sign with big white letters on it. Flat, or perhaps an acute "tent" shape... but I'm only imagining.

I surely would like to see a prototype photo.
