QUOTE: One problem with the Fastrack geometry is that the "O36" straights should be 12.73" long, the 90 degree crossings should be 10.54" across, and the 45 degree crossings should be 14.91" across. If this were the case, you wouldn't need so many small "fitter" sections for standard track layout configurations.
