What Fred said. The minimum radius in a #4.5 (which is the Atlas "#4") is 20", so the layout limit will be the 18" radius curves, not the turnout. That's only for a short distance in the turnout, the overall substitution radius of a #4.5 is about 35" radius. My 4-8-4 will negotiate an Atlas #4 just fine, but not at 'warp' speed.
