Recently, high speed train became the mainstream of the public transportation in Korea. Thus ride quality level of the passengers or train drivers is important in the viewpoint of ride comfort. In this paper, we evaluated the ride levels of high speed train. We measured the carbody accelerations for power car and passenger coach of high speed train and evaluated ride levels. As test results, the ride level of power car is higher than that of passenger coach. We think that this result is caused by primary and secondary suspension structure of the bogie system. We expect that these test results is useful in the area of bogie suspension design of railway vehicle.
