TOWARDS THE DESIGN OF RAIL TRACK FOR HEAVY AXLE LOADS

Historically railway track design has been based upon experience, empirical equations and simplified theoretical models. Despite the deficiencies inherent in these procedures they may be utilized to form a preferred design approach for heavy axle load conditions. This paper will discuss the available methods, their applicability, and their limitations. In the long term, however, newer models which incorporate a design-maintenance interaction are necessary for the development of a cost optimum track. As a step in this direction, the prediction of ballast deformation under repeated loading, a factor not considered in present design procedures, is examined.
