A short survey on modern track maintenance methods is given, concentrating on the developments in recent years. The ongoing refinement of the machinery should be shown as the influence of IT-solutions. On top the economic view to the track infrastructure is briefly demonstrated. Further developments in track hardware solutions must respect the obtained high level of track work mechanization. H...

In present study, a mathematical model of the vehicle–floating slab track (FST) interaction is established to investigate the coupled behaviour of vehicle–track system. The FST is modelled as the double Euler -Bernoulli beam including the rail and slab. The railway vehicle is simplified as a multi-rigid-body model. The wheel–rail interface is treated using a nonlinear Hertzian contact model, co...

Nowadays, the increase in heavy freight rail transport and high-speed train (HST) operations has encouraged scientists to investigate dynamic response of structures under moving load using analytically numerically computational methods. In this study, analyse vibration structure, been modelled as continuous Euler-Bernoulli elastic beam system. The effects some basic parameters such track founda...
