ALLOWABLE GROSS LOADS ON VARIOUS RAIL SECTIONS

File name is RAILSTR. Computer Program. Application: Used as a one-time guide for determining the maximum allowable loading on various rail sections. Contains many assumptions and some "retrofit" based on actual loadings previously known to have been carried. This program computes the maximum allowable total gross weight for any type rail equipment with identical axle loads on 15 different rail sections. The theory and formulas are based on the rail acting as a continuous beam on a continuous elastic base (AREA proceedings of 1918, Vol. 19, pages 875-1058). Two moduli of elasticity of rail support are assumed for each rail section, one for "good roadbed and one for "poor" roadbed. Input consists of all information required about the axle configuration of the equipment being considered. Output includes documentation of the input, a listing of each rail weight and the assumed impact for each, and the allowable gross weight for good and poor roadbed for each rail section. This program makes many assumptions having to do with roadbed, impact, and unit stresses which may or may not be justified.
