Flag stops?

Lee Bishop

I have all the books on the ET&WNC, but I don't recall ever seeing anything about the use of flag stops along the route. Were there any flag stops? If so, what color flag did they ever use to signal the crew to stop?
I'm asking as I was thinking of adding a flag at a small depot on my ET-themed layout and would like to get the color of the flag correct if they ever did this.
