Repair quality in a depot can be influenced by an after-repair control, carried out either by dint of simple tools and devices or within debugging by means of an EMU train testing under a contact wire in several different operating modes. Such approach presupposes substantial time expenditures, which count up to 30 % of the whole processing cycle, and the results are subjective due to different levels of executors’ qualification and responsibilities.
To change dramatically the actual situation and to increase the repair quality of motor driven rolling stock (MDRS) within a simultaneous reduction of an obligatory control duration and labour intensity, one can use automatic systems for comprehensive monitoring.
Well-known developments in the field of railway transport health diagnostics possess a low degree of a unit control procedures automation within diagnostics and diagnosis-making and are focused on a locomotive rolling stock (electric and diesel locomotives), which does not allow to use these developments for EMU-trains electrical circuits diagnostics due to considerable structural and principal differences from MDRS.
The article contains the results of development and industrial application at “Russian Railways” JSC of the comprehensive system for EMU-trains sections diagnostics COMPACS®-EXPRESS-TR3, which provides an off-line automatic reliable and complete MDRS health monitoring in the depot conditions.
