Realistic like real track gravel! Ballast and stones play a very important role in the realistic design of model landscapes. Track gravel is usually mined regionally, reflecting the color of the rocks and stones from that area. With the new gravel varieties from NOCH, you can ballast your track beds extremely realistically. The gravel is available in four different colors and two different grain sizes for the H0, TT, N, and Z scales. The varieties mix well with each other, creating entirely new, individual colors. Additionally, new coal is available for detailing locomotives and depots. This coal is made from a material that closely resembles real coal!.
