A field measurement of vibration was performed on the Shanghai Maglev Train Line in China. In the paper, according to the data measured, characteristics of vertical vibration attenuation of the elevated maglev transportation are analyzed. Variations of vertical acceleration level of ground vibration in relation with train speed are investigated. And the differences of vibration between elevated maglev transportation and elevated rail transit are compared. The results show that when the maglev vehicle speed is 150-250 km/h the vibration level away from centerline of 30 m attenuates under the limited value of environmental requirement. With the increasing distance from the track centerline, the difference of vertical acceleration level with different train speed is decreasing. Comparing with elevated rail transit, vertical vibration of elevated maglev transportation attenuates with distance more obviously.
