ANALYSIS OF LATERAL RAIL RESTRAINT

D. Y. Jeong, M Coltman

Abstract

This report deals with the analysis of lateral rail strength using the results of experimental investigations and a nonlinear rail response model. Part of the analysis involves the parametric study of the influence of track parameters on lateral rail restraint. These parameters include rail size, rail support characteristics, and wheel versus truck loading. Based on these results, safety limits on allowable rail restraint degradation for low speed track are presented.
