The report first reviews the methods presented in the literature for the stress analysis of the railroad track components and the results of a variety of validation tests. It was found that the equation El(w to the iv power) + kw = g yields deflections and bending stresses in the rails of lingitudinal-tie and cross-tie tracks that agree sufficiently (for design purposes) with corresponding track test results, provided the coefficients that enter the analyses are properly chosen. This is followed by a review of discussion of the methods for determining the coefficient that enter these analyses. The report concludes with recommended analyses and test methods for the determination of stresses in the rail-tie structure. (Kursetz)
