The midpoint chord method can effectively control the track irregularity of the designated band that affects the driving safety and comfort. It is mainly used to measure the track static irregularity. However, its low measurement efficiency restricts the development of track ‘state-maintenance’. To solve the above problems, the track dynamic irregularity is output according to the midpoint chord. The correlation between the dynamic and static chord measured values with the chord length and the irregularity wavelength is analyzed. The dynamic track irregularity is outputed according to the midpoint chord measurement. A dynamic chord measurement method is proposed, that can evaluate the dynamic smoothness of the track, and studies the mapping relationship between dynamic irregularity and static irregularity. The results show that, the dynamic high-pass filter amplitudes of 42 m and 70 m are equivalent to the measured values of 10 m chord and 20 m chord respectively. When the irregularity wavelength is greater than 70 m, the 120 m dynamic high-pass filter amplitude basically corresponds to the variation law of 40 m chord measured value. The track dynamic irregularities with cut-off wavelengths of 42, 70 m and 120 m have the best correlation with the dynamic chord measurement waveforms with chord lengths of 20, 30–40 m and 30–60 m respectively. The maximum reasonable chord lengths of the dynamic chord measurement method are 20, 30 m and 40 m respectively. The adaptability of the dynamic chord measurement method has been verified by the measured data of subgrade and simply supported beam sections. In the subgrade settlement section, when the chord length is 60 m, the place where the static chord measurement value deviates significantly from the dynamic chord measurement value in the negative direction is the settlement point, and the places where the adjacent two sides deviate from the dynamic chord measurement value in the positive direction are the beginning and end of the settlement section.
