The tall brick R&H Pelletizing Cooling Tower building at the back right-hand corner of my model train layout was made to cover a triangular wood support brace which connects the back of the structure with the main body.
The fake building was constructed from foam core art board and covered with printed brick paper. The windows and doors are printed paper as well. Ten years of storing, moving and setting up the layout have taken their toll on the building, leaving it with dents and creases near the top.
To cover up some of the damage, I fabricated a removable capstone surround from basswood which I painted a light gray concrete color to resemble real coping.
