Investigation of vibration is an important topic for the purposes of ride comfort in railway engineering. The vibration of rail vehicles becomes very complex because it is affected by the condition of vehicles, including suspensions and wheel profile, condition of track sections, including rail profile, rail irregularities, cant and curvature. To get the proximate approach for reality is the main object for the designer for the ride quality. So, during the obtaining of mathematical models, it is too important to consider all motion freedoms such as rolling, yawning, pitching, longitudinal, lateral and vertical motion. In the present paper, the mathematical model of rail vehicle and related motion equations are established for a six degreess of freedom rail vehicle model consisiting vertical and pitch movement of the vehicle and then, the steps for transferring the related mathematical model of the system to the MATLAB for the solution are presented.
