Wow on some of these shelves, I feel like the Beverly Hillbillies in comparison. Here are the basic ideas I used. I think I stole the shelves on the side of the layout from @stangtrain. Otherwise on the wall, we have the standard 1x4 with simple standards and the cabinets are Ikea book shelves with extra shelves added. They are not great for display obviously but a lot better than storage under the layout in tubs. At least you can easily get to what you want, like the caboose you want to run.
