TRACK LOADING FUNDAMENTALS--7 VARIOUS SPEED EFFECT FORMULA

This document discusses some formulae which are used to determine the permitted rail speed. Included are AAR, Indian Railways and Petersen formulae. The author suggests that rail speed is "a computed value, deduced by the elastic theory of the primary flexural stress at the base of the rail not exceeding the allowable stress value for the rail steel." The resultant value also includes an allowance for impact or speed effect.
