COPYRIGHT © AREMA : 26 of 44 Turnout Size and Speed Turnout size is ratio of length to spread measured at the frog: Number 9 The higher the ratio, the smaller the angle, thus the higher the speed. General rule of thumb: Double the size and round off to get the speed through the turnout (straight move speed is not affected on a tangential turnout) 2”3” 9”
