In the paper the spring-mass system describing the moving load, determined with the Hertz theory, was replaced with the spring-mass system with an inertial part being in contact with the beam, rail, or a track. Computational problems can be reduced significantly. Results are qualitatively and quantitatively improved, especially at higher range of the speed, related to critical values.
