Abstract

Characteristics of track situation and loading for urban, suburban and regional rail transport are pointed out. Short description of the advantage of the continuous welded rail track is presented. The elastic-plastic model of the continuous welded rail track structure with the effect of the vertical load on longitudinal resistance is applied. Train braking/traction forces as well as homogeneous and non-homogeneous thermal loading are considered. Applications of the model for analysis of the continuous welded rail track behaviour in sharp curves, high gradients and turnouts are presented. Calculations are carried out for track and load parameters typical for the urban, suburban and regional rail transport. The possibilities of application of the model fo
