Formulas are proposed for calculating rail depression under wheel load rolling on supports one after another on track where rails are supported on equi-distant springs with equal stiffness and where some gaps exist between rails and springs; assuming that gaps are distributed in magnitude of exponential random digits whose mean value is 1 mm and rail supporting springs are spaced at equidistance of 60 cm and stiffness is equal to 20 ton/cm, rail depression at 120 successive supported points is calculated by means of computer for Japanese National Railroad rail types of 30 kg, 40 N, 50 N, 50 T, and 60 kg.
