Ballasting has started. Note that the first part to be ballasted is where a tunnels is. Ballast is shifted gravel from the soft shoulder of the road outside the house. This has a nice mixed texture and colour. When the ballast is in place a spray of water with detergent to "wet" the surface is followed by acrylic matt medium diluted with windshield washer fluid. This is put on with an eyedropper. The matt medium does not dry as hard as diluted white glue does. It can be peeled off plastic ties if you ever want to resuse the track. The pieces of the side walls are painted a cement colour.
