I wonder, though, if the issues mentiioned here can be attributed to wood movement. I understand wood movement well as I am a woodworker as well. Wood does expand as humidity and heat rises. However, everyone here tells how the track bulged during the summer. If it were wood expansion, the track should be pulled apart rather than bulging. Also, since most everyone works with primarily plywood, expansion should not be an issue as plywood is dimensionally stable.

Ah, well, track bulging occurs when the table contracts, Gaps also appear between the sections, but the track remains operational.
Plywood is EXPENSIVE. LIONS do not use plywood. LION builded tqables from used 1x4s salvaged from buildings that we have torn down, the track deck is made of 1/2" Celotex, a sort of Celotex that has not been commercially available since the introduction of fire codes, but I had ten sheets of the stuff left over from a remodling job. Makes an excellent foundation for railroad tracks, lighter and more stable that homosote.
But alas, I used up the last ten sheets that were availavle on the planet Earth.
