I have two model railroads in my basement, both built on Mianne benchwork, and I have asked myself the same question for years. But, in my opinion, the Mianne benchwork (legs and beams) is the quickest, easiest way to build a strong, lightweight train table that is durable and looks like it was built by a professional. One layout is 12’-by-8’ (assembled in 1999) and the other is 10’-by-5’ (assembled in 2014).
The legs and beams are assembled with "camlock" fasteners that tighten (or loosen) with just a screwdriver. So those parts of the table go together and should come apart easily. The question is how you fasten the plywood table top to the benchwork. That can make the disassembly difficult if you use strong fasteners that become inaccessible once the table top is covered with track, structures and scenery.
On my 12'-by-8' layout, I used fasteners supplied by Mianne that connect the underside of the plywood to the table frame so the fasteners are not visible or accessible from the top of the table. That layout would now be difficult for me to take apart.
On my 10'-by-5' layout, I didn't fasten the plywood to the benchwork at all. The two 5'-by-5' plywood pieces just lay on top of the frame. Once they were in place, I glued two wood blocks (3 inches by 3 inches by 1/2 inch thick) to the underside of each piece of plywood and positioned them against the inside corners of the frame at the ends of the table (see photo of table underside). These blocks lock the plywood into position on the frame but allow each 5'-by-5' section of the plywood to be lifted off the layout individually and without damage if it has to be moved. Most of the seam between the plywood pieces is covered by structures and is not visible. Thus, the layout is modular and can be disassembled easily. The Mianne beams and legs will be easy to disassemble. Just turn the “camlock” fastener ¼ turn counter-clockwise with a screwdriver. The pieces will come apart and the “camlock” fasteners can be reused for reassembly.
This method has worked well for me. The layout is solid but should easily come apart without damage and be transportable. My plywood table top is covered with extruded pink foam (up to five inches thick) glued to the plywood as a scenery base. I glued cork roadbed onto the pink foam and simply fastened the Atlas O track into the cork and pink foam with Atlas track screws. My 10’-by-5’ table was assembled in 2014 and after 8 years of operation, the track is still secure onto the cork roadbed.
I should also mention that on my layout, the plywood overhangs the frame by about 6 inches on each edge. The table is 10’-by-5’ and the benchwork is 9’ by 4’.
If I were to build another layout, the first thing I would do would be to order Mianne benchwork.
