The aim of this research is to measure the damage caused by the vibrations of passing trains. In order to determine the vibration levels of the trains, twelve points along the Honam, Cholla and Kyungjun lines were chose. There are two goals to be achieved from the data gathered. The first is to determine whether or not the trains are operating under governmentally determined levels. The second goal is to establish countermeasure in order to minimize the effects of the vibrations on the people who live near the train lines. A vibration level meter was used to measure the vibration levels at all twelve points at times when no trains were travelling and at times when trains were travelling. As a result, it was found that Saemaeulho and Mugunghwaho, had a higher vibration level of 2 - 3 dB than Pidulgiho and freight trans. There were no relationship between speed and vibration level. The vibration levels did change according to capacity and size of the engine. In such cases there was a difference of 2 - 7 dB. Where vibration proof ditches were in place, the vibration level were decreased by 3 - 6 dB. The practical decreases in vibration levels was similar to the theoretical decreases.
