The base of the roadbed is made out of 1/2-inch ceiling tile glued to the MDF sub-roadbed (see my Ceiling Tile Roadbed article). Before I installed the MDF sub-roadbed on the layout, I used it as a template to trace the shape onto the ceiling tiles. These were then cut and glued to the MDF after it was installed.

Ceiling tile generates a lot of dust. To cut down on that dust and to avoid seeing the white through the ballast, I decided to paint the tops of the tile with an earth-tone color. I will cut the slope of the roadbed later on, and I will then paint the rest of the ceiling tile and the MDF sub-roadbed to protect it from moisture and to avoid generating more dust.
