: What coarseness ballast should I use for my OO scale
Ballast comes in varying degrees in coarseness, fine medium and coarse. For OO scale the most realistic would have to be medium . OO gauge is 1/76 scale so measure a few ballast stones and multiply the size by 76 to check whether it would be correct in real life. Although there is nothing to say that you cannot use any of the others on your layout. You could use coarse ballast in your
