Abstract
In this paper, it is introduced that the distance of high speed bogie development for through operation of Shinkansen and conventional line that began in Fastech360Z. In particular, it is focused that the design related to installing of anti-yaw damper. To restrain the environmental noise, bogie side cover must be equipped. So, mounting location of anti-yaw damper is limited and vertical body elastic vibration becomes easy to occur. We repeated trial and error, and developed bogie for series E6 on the basis of gained knowledge.
