A sound monitoring of railway vehicles is essential for securing ride comfort and safety. However, the sound monitoring system equipped with many sensors may not only be expensive, but also require much expense for maintenances of the sensors. Therefore, we have developed a method to evaluate the sound conditions of railway vehicles with fewer sensors. At the first step of the study, we examined which place will be the best location of a bogie to install an accelerometer for the sound monitoring, if only one place is allowable for installation. We demonstrated experimentally that our method is effective in monitoring various lateral damper faults and generation of hunting of a bogie. We also confirmed that Support Vector Machine as information processing technology is capable to classify the lateral damper sound conditions.
