Description	The superconducting magnetically levitated train (JR Maglev) has been developed. Electrodynamic suspension realizes stable levitation and guidance without gap control. As the damping against the bogie vibration is small, the damper coil system has been proposed to control vibration of the bogie. Superconducting (SC) coil quenching is one of the most serious problems. Although the effect of the damper coils in the case of SC coil quenching has been confirmed, influence of the position of the quenched coils on the bogie motion is not shown. In this paper, the dependence of the quenched coil position on the bogie is studied. When the end coil of the bogie quenches, the levitation force and guidance force reach twice and five times compared with the ordinary force. In the case of inside coil quenching, the exceptional force is supported by each side of the SC coils. Thus, its influence becomes small. Even in the case of end coil quenching, damper coils control the large vibration.
