Load and stones play a very important role in the realistic design of model landscapes. Track gravel is usually mined regionally and therefore reflects the color of rocks and stones in the region. With the new PROFI Ballast types from NOCH, you can, among other things, load your rail beds extremely realistically. PROFI Ballast is available in four different color shades and two different grain sizes for gauges H0, TT, N and Z. The types look great when mixed with each other. This creates completely new, custom colors.
