Most of us struggle to find enough space in our layout rooms to store all of our trains, kits, scenery supplies, etc. The best solution can be some sort of cabinets but good cabinets can be quite expensive. When I remodeled our kitchen years ago almost half the budget went to new cabinets and those were no where near top of the line.
What I have been using for my train room are un-assembled cabinet kits that I buy at Ikea. They are well designed and easy to assemble. I mount them above the layout and mount layout lighting under them.
The east end of the Wesso section can be seen at the right of this photo. The layout will be continuing under these new cabinets.
Led lighting for the layout and lighting valance will be mounted along the bottom of the cabinets.
Wheels have been installed under them and they are now used as base cabinets and working surfaces. The one in this photo supports the paint booth. Paints and scenery materials are stored in this cabinet. The other one serves as a shipping table and holds shipping boxes and packaging material. These cabinets are about 15 years old now and have held up well despite being at the low end of the price range for cabinets.
