    They will get dirty very fast, either from dirt thrown around by passing trains, or by the brake dust.

      It shouldn’t be too hard to clean them with something running on the tracks, but it does seem less than ideal.

        A chain or wire hanging off a train car and dragging along will “clean” them real quick…
