PERMISSIBLE LIMIT VALUES FOR THE Y AND Q FORCES AND DERAILMENT CRITERIA. EFFECT OF TRAIN SPEED ON THE PERMISSIBLE MAXIMUM VALUE OF LOAD (LATERAL LOAD) FROM THE POINT OF VIEW OF TRACK DISPLACEMENT

For safety reasons the study was divided into two complementary phases, viz. running tests on the track and simulation tests on a rig. The former provided information about the effect of speed on the transverse and vertical sleeper reactions during the passing of wheelsets applying loads lower than the limit of transverse track displacement. The latter extended the tests up to the point of track displacement. The results obtained showed that neither the length of the influence line of the sleeper reactions in the track nor the maximum permissible lateral force on the rig varies to any marked extent with the speed. These findings prompt the conclusion that the permissible lateral force does not vary significantly with the speed.
