THE STRESSES OF THE TRACK UNDER MIXED TRAFFIC AND THE ADVANTAGES RESULTING FROM INTERCONNECTED SYSTEMS (ROME-FLORENCE LINE)

For new lines the idea of mixed traffic with speeds beyond 200 km/h, even apart from the more severe conditions to be imposed on the alignment both from the geometric and from the kinematic aspect, means nothing less than a more complex problem in regard to the track concerning the possibility of maintaining high standards of quality and the innovating trends aimed at strengthening the permanent way. After having dealt with the most prominent features of the dynamics of the track with regard to the stability of the lateral bed under the effect of transverse dynamic stresses transmitted by the vehicles through the wheel-rail interaction, the article refers to the first results of new tests carried out under dynamic load, recently finalized by the FS, and which have a considerable interest. The levels of stresses corresponding to the various types of existing vehicles for fast and "slow" traffic are quoted and then the advantages resulting from the interconnected lines are defined, by referring more particularly to the putting in hand of the project, already partially completed, of the Rome-Florence "Direttissima" suitable from its nature, for the adoption of the optimum operating solutions within the limits of its compatibility with the traditional permanent way.
