Great shelves, everyone.
My design criteria for shelving: nothing fancy, use readily available lumber, and retrofit them under the layout overhang - just hold the trains, mainly items that are a PITA to get in and out of their boxes, for easy swapping out. Long passenger cars mainly, of which I own 7-8 sets, and usually run one or two at a time. So, I built custom-style extra-deep shelves that hold two trains in depth. The shelves turned out very sturdy, and can hold heavy die-cast engines as well. So far, I've built 3 custom units - each with varying width to fit under my layout, and have at least one more to go. As seen in picture, below, I limited each to 30" high with a theoretical idea that someday I would retrofit a subway line, which would need to travel on top of the shelves in those areas where shelving was installed. I am pleased with the results.
