Data acquisition plays a significant role in determining and optimizing maintenance actions for railway wheelsets, as small inaccuracies translate into decreasing useful life, unnecessary downtime and costs. In this study, a comparison between data acquired from three different inspection devices: i) manual (gauge device), ii) laser and iii) under-floor wheel lathe; is presented for three wheelset parameters: flange thickness, flange height, and flange slope. Using condition data to assess the agreement of measurements by contrasting several devices in a real-world case study is challenging, as many of the commonly adopted assumptions in controlled experiments are not met. Therefore, a linear mixed model (LMM) approach is proposed to enable a comparison of performance under those limitations. Findings support the use of LMM and showing its ability to capture and account for the differences among the various groups, highlighting statistical significant performances of the inspection devices.
