This paper describes an analytical study on the effects of airspring deflation on the running vibration of railway vehicles. The vertical vibration characteristics, containing car body bending modes, are investigated for the situation excited by running on the track with vertical irregularities. The vibrations caused by the track irregularity of practical amount are evaluated with the value of the riding quality level, L_T, calculated from the car body acceleration, and they are compared between the conditions that the airsprings are normal or deflated. The running speed is broadly varied in the evaluation and suitable running speed is examined for the train operation under deflated airsprings.
