A model was developed for analyzing the track critical velocity in this study. It is a double-beam model including rail, rail pad, track slab and cement-asphalt mortar (CA mortar). The model vibration differential equations were transformed by the mobile coordinate system and the Fourier Transform. Then the numerical solution could be easily obtained based on Matlab software. The results from this model were presented for track critical velocities at different rail pad stiffness values. According to these results, there are several track critical velocities in the track structure and the stiffness of rail pad has no obvious effect on the minimum track critical velocity which is the most important velocity in reality.
