TRACK STRUCTURE--OPTIMISATION OF DESIGN

A design procedure based on classical theories, permissible stresses and qualitative and quantitative performance correlations, as used by the South African Railways, is explained. Track structure running top performance is evaluated as a function of ballast and formation stresses and traffic. Different traffic mixes are reduced to a common denominator of equivalent theoretical traffic in terms of a reference axle load. The latter concept is in need of quantitative, practical evaluation.
