Self-vibration characteristics of the rail beam structure.

Modal	Self-vibration frequencies (Hz)	Period (s)	Modal characteristics
1	39.97	0.025	Positive symmetrical torsion
2	50.02	0.02	Positive symmetric vertical bending
3	54.28	0.0184	Antisymmetric vertical bending
4	61.18	0.016	Antisymmetric torsion
