Lines of Development of the AS URRAN in Terms of Track Switching Facilities
Abstract
Railway network-wide introduction of Automated System for Resource and Risk Management and Reliability Analysis at the Life Cycle Phases (AS URRAN) allows for life cycle planning of infrastructure facilities based on esti-mation of their actual condition by reliability indices with due account for possible risks. To support the URRAN con-cept there were put into execution several maintenance standards STO JSC RZD, containing general safety and risk re-quirements relative to railway transport. The paper tackles the improvement aspects of the AS URRAN operation in the context of track switching facilities. There are recommended development and upgrading patterns of the AS URRAN to be listed as follows: • Bringing AS URRAN employed terminology in the part of reliability indices to conformity with the characterized parameters; • Change-over from reliability indices of the “reference turnouts” to the same of real ones with allowances made for their actual operating conditions data. Designing in capabilities of by-type failure analysis of technical means to be performed in accord with “Qualifier of Objects and Failure Causes of Technical Means” employed by the Comprehensive Automated System for Accounting and Restoration Control of Failures and Reliability Analysis of Technical Means (KAS ANT) and with due regard for pro-visions of “Qualifier of Turnout Components Defects and Damage”.
