Reply to "New Atlas Turntable"

I spent considerable time on smoothing/leveling the layout table surface prior to positioning the TT.  All effort for naught.  Same problem I had with the earlier model: weight of engine causes the platter to sag which results in derailment.  All of my motive power units are scale, but the problem occurred using the lightest engine I have, an 0-8-0 steam switcher.  Since there seems to be a number of members here that have had success with the new model, don't be discouraged by my experience.  I may not have the right touch to fix the problem.
