In this paper the case of the system “railway vehicle rolling on a railway track with defects/faults” is investigated based on a simulation technique of an ensemble of springs and dashpots leading to the formation of the differential equation of this system. The application of the Fourier Transform on this second order differential equation of motion leads to its solution for the case of the Suspended/Sprung Masses of the railway vehicle and the approximants of the standard deviation of the vertical acceleration which appears on the vehicle’scar-body
