LIMIT OF TRAFFIC LOAD CAPACITY FOR S 49 RAILS IN TRACKS AND SWITCHES

Werner-Wilhelm Kraft

Open publisher page 0 citations

Abstract

Owing to the increase in axle load, travelling speed and traffic volume, S 49 rails have in many cases reached the limit of their load-carrying capacity. The usual practice of evaluating the vertical and lateral wear of the rail head alone is no longer sufficient to determine the point in time at which the rails have to be replaced. The factors, ultimate traffic load capacity, type of track construction and behavior of rails not replaced in time, are discussed and explained by means of examples.
