My dad custom made my shelves. The shelves are 1x4s that he ran through a dado setup on his radial arm saw to produce slots spaced for the wheels. The backing is bead board and the edge trim is off-the-rack stock from Menards. The colors are standard paint colors from Lowes that match the original green and cream Lionel Hellgate bridge. I have four of these shelves (all of different sizes) on the available wall space in the train room.
