Jim Robinson with Bridgeboss built my platform and also an Engine Shed. Great work. If you are travelling over 2 line curves, consider bridging both with the legs on the outside for the columns. If your legs on the columns are between the 2 lines, you can go nuts trying to get around the curves. I suggest a Bigboy or something articulated to help in the planning.
Also, pay attention to the overhang on 21" cars.
