The paper presents the background of the diagnostic analysis for railways and trains (DART), automatic diagnostic analysis tool for the track geometry measurement data - as separate track data files or track data read from the database. The diagnostic module indicates the 'weak locations' in the track, which can be further analysed in detail by the diagnostician. Detailed analysis of track geometry parameters' plots assists taking the right decisions pertaining making urgent local repairs, i.e., to ensure safety of train operation. The knowledge of the synthetic track quality coefficients is required to take the economically justified decisions connected with planning of major overhauls of the longer track sections. These decisions call for analysis of the track geometry changes in time. This analysis may be carried out by the dedicated software for management and analysis of the track measurement results acquired for track gauges and geometry cars. DART track diagnostician's computer assistance system helps to save some 90-95% of labour consumption. All software mentioned in the paper has been developed within the framework of the project. The system presented in this paper has been thoroughly successfully tested by PKP PLK S.A. in Poland and by Volker Stevin Rail & Traffic in The Netherlands.
