Serviceability and performance capacity of repaired equipment is not objectively a guarantee of its correct operation as a part of this or that electric multiple unit system. Relationship between the elements, devices and units can be broken as a result of installation defects, damage can appear while transportation, assembling and subsequent debugging. The defects appearance at this stage of the technological cycle leads not only to duration increase of EMU putting into operation (debugging period), but, in the case of a defect omission, to spoilage and failures on the line.
Improving the quality of the motor driven rolling stock with a simultaneous reducing of debugging duration and complexity is possible on the basis of automated systems for comprehensive diagnostics of repair and assembling quality of the most complex and critical EMUs systems that provide a reliable quantitative and qualitative assessment of their technical condition, in accordance with the guidelines requirements.
The article presents some results concerning development and application of systems for comprehensive diagnostics of EMUs repair and assembling quality. EMUs are widely used at enterprises of «Russian Railways» JSC and at factories which are prospective for the railway industry being a means of improving reliability, maximizing EMUs exploitation with a simultaneous reducing of costs for repairs and speedy reconstruction of repair system on safe resource-saving basis.
