The article discusses a preliminary concept of a method enabling the identification of chosen rail running surface defects, such as squats, spalling, and running surface defects, by analysing the parameters of vibration signals. It features a description of the methodology of the conducted tests, the scope thereof, and the selection of the measurement points with specific defect types. The article covers selected results of vibration tests, the results of analyses of recorded signals for defective track sections and those for control track sections. The presented measurement results have been obtained for the technical–operating conditions occurring on railway line no. 213 Reda – Hel and line no. 131 Chorzów Batory – Tczew. The preliminary test results and conclusions included in the article show that it is reasonable to pursue further research into the phenomena involving the utilisation of vibroacoustics in rail performance diagnostics Keywords: vibroacoustics, squat, spalling, running surface defect
