Best ways to change ballast colour

[Tom]

I had that problem once before, and found that the best way (cheapest, easiest and less messy) to do this was to simply wait until the glue had fully dried and then go back later with a dry medium bristle toothbrush and scrub in the direction of the track. I scrub between the rails and then do the sides. Something in the ballast comes up and weathers it REALLY nicely. I tehn clean the rails really god and call it done. It'll definitely darken your ballast and weather it and doesn't cost anything (unless you have to go purchase a new toothbrush, and what does an cheap toothbrush cost anyway, $3, $4 bucks?). Minimal amount of work too, you really don't have to scrub too hard or too much to accomplish the results you want.
