Abstract
The railway track is analyzed as a complex technical system, the management of which is based on regulatory approaches that limit the predictive control of critical sections. A set of system analysis methods has been applied: structural decomposition, functional and structural analysis, classification and multi-criteria analysis. The hierarchical interrelation-ships of the elements of the upper and lower structures have been revealed, and the cascading nature of degradation has been established, where the malfunction of the underlying element acts as the primary factor in the destruction of the overlying ones. The division of components into critical (providing instant safety) and fundamental (determining long-term stability) is justified. A multilevel life cycle model is proposed, which establishes a discrete scale of states correlating with the probability of failure. The concept of a hybrid digital twin integrating stationary sensor networks and data from mobile diagnostic complexes has been developed.
Objective: To systematize the main components of assessing the efficiency of the use and development of railway infrastructure for the scientific justification of its creation, operation, and modernization in the context of the transformation of the national transport system and economy, as well as adaptation to new lo...

The deployment of digital technologies on the railway, especially the widespread deployment of the ETCS system at the L2 application level, enables direct control of railway vehicles, i.e. vehicles are permanently connected by a radio system with the infrastructure interlocking system. One of the expected benefits of u...

Frost heave of railway subgrades in seasonally frozen regions can severely threaten the safe operation of railway lines. However, the evaluation criteria for railway operational safety remain inconsistent. In this study, a discrete element model of a ballasted track–subgrade system and a vehicle–track dynamic model wer...

With the increasing application of power electronic equipment in electrified railways, low-frequency oscillations resulting from impedance interactions between trains and the traction network (TN) have become a significant factor affecting system stability. In passenger–freight mixed railway systems, trains supplied by...
