The subsonic Capsule Train adopts the non-contact magnetic levitation system with SCM. In order to investigate the effect of the subsonic Capsule Train on the driving dynamic characteristics and ride quality of the vehicle, we investigated the dynamic characteristics of the Capsule Train according to the traveling speed based on the initial concept of the subsonic Capsule Train. Simulation was performed by deriving an equation consisting of a dynamic model with 15 degrees of freedom for vertical, lateral, roll, pitch, and yaw direc-tions for a Capsule Train consisting of one body and two bogies. In this study, only the vi-bration in the vertical direction was addressed. The side EDS (Electrodynamic Suspension) magnetic levitation trains system, which has a similar concept in the case of Capsule Train levitation stiffness and guidance stiffness, was applied. The simulation was carried out for the speed range from 210km/h to 1080km/h. Based on the simulation results, the change of the vertical displacement in the time domain was confirmed, and the frequency analysis were performed. The results of frequency analysis showed that the dominant frequency components were 0.9Hz, 14.5Hz and 15.01 Hz in front/rear bogie and 1.1 Hz and 1.64Hz in carbody.
