As part of a new layout in my attic I am starting with a terrain for trains Smokey Hollow and thinking about extending it with wire shelving materials from Home Depot or Lowes covered wth pink foam. I feel that you could use the wall brackets to put the backdrop on with magnets and raise or lower part of the shelf to put bridges along the wall. Will have a turnaround at the end and back to the terrain-for-trains starter module and a hollow core door for a yard. My question is has anyone used this type of support for the around the wall layout and what are the drawbacks. It would seem that you could find a way to hold the shelf support brackets down so that it would not fly up if accidentally hit.
