26 COPYRIGHT © AREMA 2012 7: 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”

27 COPYRIGHT © AREMA 2012 7: 27 of 44 Purpose of the Guard Rail Not all turnouts require guard rails: self-guarded frogs, moveable point frogs
