    The paper deals with the dynamic analysis and evaluation of the driving characteristics of the selected railway vehicle through computer simulations on virtual and mathematical models. Approaches and methodology from the point of view of creating a virtual model of a railway vehicle as a multi-body system are described in detail., its components and their interrelationships, with the help of which it is possible to obtain the results of a simulated driving of a vehicle with specified parameters of the mechanical system of the vehicle and the track. Practical calculations are performed using the Simpack computer program.

    The subject of the research is the development of a technical feasibility study that will deal with the concept, safety and related industrial research for the replacement of diesel traction by hydrogen fuel cell traction in the railway vehicles series 861. Part of the research is also the operation of such a source of traction, the assessment and evaluation of risks, especially from the point of view of maintenance and operation. The research result will be a technical study based on numerical simulations of static and dynamic loads, energy management of the fuel cell traction and requirements for the inclusion of such vehicles in regular operation on non-electrified tracks of the Slovak Republic.
