In the current paper, various possibilities of minimizing consequences of high-speed rail vehiclederailments have been studied through a combination of empirical observations and multi bodysystem (MBS) simulations. In order to assess the appropriate measures and features for an increasedderailment-worthy design, a comprehensive MBS model is developed to predict the pre and postderailmentvehicle behaviour. Preventing wheel flange climbing derailment after axle journal failureson curved track is accomplished by implementing mechanical restrictions in the bogie frame. Threealternative substitute guidance mechanisms are presented and a systematic feasibility analysis forone of them, a low-reaching axle journal box, is presented. Three conventionally coupled passengertrailing cars are investigated after derailments on tangent and curved track as a function of themaximum centre coupler yaw angle, carbody height of centre of gravity, coupler and bogie transversalbeam height. Furthermore, the articulated train concept is investigated as a function of different intercarbodydamper characteristics.
