Abstract-The paper presents analysis of the results of template 873 measurements which is a tool used for inspection in wagon depo. The data obtained were analyzed to confirm the stability of inspection results. It was shown that the measurement and determination of the final result by calculating the average value causes misleading results. Also random factors which affect measurements are presented. The subjective factor in this process is from the calibrator. To make measurement process more stable we need to reduce the effect of these factors. One of the ways to improve measurement process and make it more stable is its automatization. Improving the accuracy of measurements is one of the main objectives concerning this issue.
