THE EFFECT OF LONGITUDINAL FORCES ON CONTINUOUSLY WELDED TRACK AND ON TRACK BALLAST

The properties of the ballast under the influence of longitudinal forces or longitudinal stresses in continuously welded track are discussed. The first part of the paper deals with the different causes of longitudinal stresses. The second part is concerned with research on the mechanical properties of the ballast. From theoretical considerations and on the strength of test results, characteristic data for the resistance to longitudinal displacement are obtained. The third part deals with measurements of rail stresses encountered in tracks under traffic. A description is given of investigations based on train braking tests on continuously welded track.
