In this study, strain gauges were attached to the bogie frame for high speed cargo train whose maximum speed is 120 km/h and maximum load is about 100 tonf. By comparing the stress and vertical deflection of high speed cargo train with vertical dynamic load, 43.88 tonf on bolster as JIS with those obtained after solving by using of finite element analysis program, we could certified the reliability of finite element analysis. And we found out the optimal circular hole location of bogie frame minimized stress, vertical directional deflection after moving the circular hole vertically and laterally.
