The following conclusions are done based on the last year Association VAST practical experience in locomotive gear condition diagnostics: Efficiency of locomotive running gear bearings diagnostics in locomotive depot can be high enough to insure safety of locomotive operation, when the following problems are solved: Introduction of adaptation solutions for automatic diagnostic systems for running gear of all locomotive models, Introduction of corporate diagnostic systems that allow most qualified diagnostic experts to take part in real time diagnostics of some locomotive diagnosis and condition predictions made by automatic system independent of their location. Training and continuous qualification increase for in locomotive running gear operators and experts in diagnostics. To introduce functional diagnostics of the on-board locomotive equipment is necessary to solve organization problems and insure the required operation modes of the equipment during diagnostic measurements in depot and to diagnostic services in the depots with adapted systems for vibration, electric current and infrared analysis. For diagnostics of railway wagon and cars box bearing on special stands, the stands should be designed taking into account influence of stands on the bearing condition symptoms. The on-board stationary diagnostic systems should be introduced starting with automatic stationary data collection systems installed on the selected equipment. Measured data can be downloaded periodically to the condition diagnostic system in depot. It is recommended to collect data related to vibration, electric current, rotation speed and temperature. A special study should be conducted to find out if it is possible to conduct locomotive running gear condition monitoring and diagnostics by vibration and drive motor current analysis in locomotive motion taking into account motion influence on the measured parameters.
