The depot Anisovka for more than four years operates actively the system for comprehensive diagnostics of electric multiple units COMPACS®-EXPRESS-TR3, designed to evaluate the repair quality of series ER9, ED9 (T, M, MK) electric multiple units equipment after current repair TR-3.
For this period due to the system 90% of electric multiple units after a large-volume repair have been completely debugged (except for 10% of series ER9P electric multiple units). All defects, detected by the system, have been confirmed by the results of additional dismantling and revisions, made at the system direction. Many of the defects could not be detected during traditional running tests and under a contact wire debugging.
Experience, received during the system operation, allows to draw a conclusion that the system COMPACS®-EXPRESS-TR3 provides a trouble-shooting level of about 85%, including the most dangerous defects, which omission can lead to failures and breakdowns on the way with significant delays in the time-schedule.
The system has proved itself as a reliable source of information on the electric multiple units technical state with a high level of covering the diagnosed units and assemblies, which ensures a high level of trouble-free functioning of railway transport.
