I have applied a base coat of paint to the ground and track. I also filled in the foam core roadbed sides with Sculptamold. I like to add some earth-colored latex paint to the water before I add the dry Sculptamold. Adding this color tones down the stark white of the Sculptamold. I used a palette knife to mix, apply, and smooth the Sculptamold.
The road through the scene was made with a foam core base and Woodland Scenics' Smooth-It applied over it. I applied the Smooth-It with a palette knife. I used an old freight truck, screwdriver, and Bright Boy track cleaner to keep the flangeways and rail tops clear of the plaster.
