IMPROVEMENT OF THE RIDING QUALITY OF EXISTING RIV VEHICLES REQUIRED TO RUN AT 80 KM/H UNDER ALL LOADING CONDITIONS. SUMMARY OF THE WORK OF THE COMMITTEE

This synoptic report furnishes, first of all, the criteria retained for assessing the suitability of two-axled wagons to run at 80 km/h. One of these criteria concerns the distortion of the track and the other the riding quality (criteria bases on the use of statistical data). The report contains recommendations relevant to the execution of tests in the track (at the responsibility of the Administration). It subsequently indicates the results achieved by means of the various modifications tried and those among them recommended for the wagons considered and also the costs involved. A practical guide is given in the Appendix; it should refer the Administrations to the parts of the report to be consulted when studying the various aspects of the problem. This guide also contains a synoptic table, indicating for all the types of two-axled wagons, their possible suitability and the recommended modifications, if necessary. The report finally mentions the existence of a mathematical study carried out by the Railway Research Centre of the Yougoslavian Railways. Those Administrations encountering special problems will be able to have recourse to this study.
