Purpose: To demonstrate the practical application of a quantitative methodology for estimating the duration of the residual operation period of worn-out metal pipelines as part of a railway transport engineering infrastructure, metro networks, urban networks and industrial transport networks. Methods: The technical condition of wornout pipes was assessed by applying calculation dependencies for metal pipes with internal sediments. Results: The estimation methodology has been presented, with the duration of the operation period being calculated. The concept of operation efficiency coefficient is introduced as a major component in ensuring the reliability and safety of pipeline systems for various purposes. Conclusion: The estimation of the operation efficiency of worn-out pipelines of railway infrastructure engineering networks is proposed to be conducted applying the coefficient value of the pipe operation efficiency, depending on the thickness of their internal sediment layer. The necessity to develop specialized tables for hydraulic calculation of worn-out metal-pipe networks of railway infrastructure has been substantiated, and it has been proposed to include quantitative standards in the current regulations.
