OPTIMUM ADAPTATION OF THE CONVENTIONAL TRACK TO FUTURE TRAFFIC. STUDY OF THE CHANGE IN TRACK GEOMETRY AS A FUNCTION OF TRAFFIC. ADDITIONAL RESULTS

The report deals with changes in the longitudinal level, cross level, alignment and gauge of conventional track under traffic loading. The tests were made in the field on different track constructions so as to enable the influence of different equipment parameters to be ascertained. Generally, it appears that track deterioration is proportional to the logarithm of the tonnage carried. The results of the measurements obtained are often scattered, which indicates that many parameters are near their optimum value. It could, therefore, be thought that the conventional track is now already largely optimised from experience and that only little improvement can be expected from equipment parameter modification.
