High-Speed Rail: Excitation Frequencies and Track Stiffnessistic frequencies are most likely to coincide on high-speed rail systems are considered. Some conclusions are drawn on optimal range for the loaded track resonance and the optimal track stiffness range under different train speeds required to provide this.
