The importance of modelling and simulation in the field of railway systems has greatly increased inthe last decades. Various commercial simulation packages have been developed and are used toanalyse the dynamic performance of railway systems. However, although sometimes the user needsto analyse various non-standard solutions, the possibility to integrate further modifications into thestructure of such software is quite limited. Therefore, in some cases, in particular for specificmodelling and analysis tasks, a feasible option is to develop flexible and robust simulation toolscapable of using different configurations by modifying the models performing the dynamic analysis.The paper presents the mathematical modelling background and the conceptual design of a new of anew computational tool for the dynamic simulation of railway vehicle systems. The formulationsemployed in the proposed mathematical model are based on the multibody techniques. Thedeveloped model uses a combined frame of references that allows the use of independentcoordinates without the possibility to have singularity configurations depending on the rotationsequence. The simulation tool is designed in a flexible form that enables the study of differentconfigurations of the railway vehicles, as well as various track combinations
