I tested and what worked is to place the track on all 4 tabs but don’t use the slot in the tabs. What caught me off guard was that the specialty track itself has slots in it appropriately spaced. So I had to avoid those and just get the track resting on all four tabs. It was far enough away from the platform that I could eject milk jugs successfully.
My thought is that when I’m ready to set it on to the layout this Christmas after I fix tracks on both sides and screw them down it will be very stable.
I want to thank everybody again who pitched in an offered ideas.
as always, thanks – Walt
