I recall you recommended 6 legs. I wanted to try to minimize the toe stubbers to a minimum. I may beef up the longitudinal joists prior to adding more legs. The issue I have adding more legs is the floors in the basement are not very flat. The more legs there are, I may introduce wobbling of the table. I am intending on putting levelers on the legs, but don't want to have to readjust 6 every time I move the table.Mike is correct that foam sands well. 1/8" deflection when weight is applied probably won't be an issue, as trains weigh a whole lot less than your pushing. Eventually, depending on your layout room conditions, the wood could sag on its own. Note that I recommended that you start with 6 legs in post # 50; it looks like you do have a place to anchor them if you do add them. Cheap insurance.
I am sure that will address the deflection, but wanted to minimize the weight if possible during construction. I did add cross supports above the leg when I built it to accommodate longitudinal joists if required.
