Statistic analysis of data from renovations of freight wagons

Analysis of data from protocols that are filled during the process of qualification for renovation of freight wagons can be very useful in the process of freight wagons development and modernization in order to obtain better exploitation properties and extend periods between repairs. In this paper results for freight wagon types EAOS 1415 A2 and A3 as well as BDŻE, CFRE, CSDE, 401W, 408W, 412W are presented. 298 qualification protocols from years 2012 up to 2014 were analysed. The acquired data were analysed in order to specify the percentage of repairs of individual wagons elements. Obtained results were presented on charts. It was concluded that at this moment there is no any part of the freight wagons body shell that may be indicated as the most exposed to damage during standard exploitation of the freight wagons.
