Thanks Will for your feedback. Some good points. You didn’t mention height, but assume it depends on your overall scheme. In my case, I will raise it height enough for side materials.

Hi Gary. I always use sideboards (fascia) to protect anything soft that is above the plywood. I do not always cut the top edges of the sideboards straight, but make random waviness in the top edge that allows me to create some gently rolling landscaping that gives more irregularity in the scenery. By having an edge that projects above the track level, derailments may be less likely to end in a fall to the floor.. I hope this helps. Will
