[For the English abstract and full text of the article please see the attached PDF-File (English version follows Russian version)].ABSTRACT The authors justify the use of system engineering approach to evaluation and tasks of improvement of railway line operational reliability. Particular emphasis is placed on interdependence of infrastructure capacity and overall operational readiness of the system «railway» in terms of compliance with criteria adopted in the theory of reliability. An own interpretation of the concept of «operational safety» and factors of maintenance of track in working order is given, as well as regularity in local situations, preventive and remedial actions are suggested. Keywords: railway, infrastructure, operational reliability, track maintenance, transit capacity, system engineering, reliability theory.
