Generally, the analysis of data of the railroad components is most effective method for the efficient maintenance of railway. Especially, the tracks damaged directly by train, have as important position with the inspection data. This study suggest the Life-Cycle performance of railroad by analysis of Inspection data such as geometry measurements, ultrasonic inspections, wear, failures, corrugation, fastener check, sleeper check, ballast check. In this study, detected wear data and main factors of railroad abrasion analysis are accomplished to predict the remainder of service life of railway tracks for efficient maintenance. Also, wear-time probabilistic distribution curve which can be adapted to safety assessment is computed.
