Determining the concept of “digital twin” in 3D models of railway stations

The semantics of the concept of “digital twin of a railway station” is investigated for compliance with the existing technical and informational level of obtaining an adequate digital image of a complex dynamic system that can correctly reproduce the dynamics of technological processes and states of infrastructure objects and rolling stock under certain conditions initial conditions and factorial influences. The digital twin of the station is a visualized model image of a complex technical system, in which the model rules constructing the technology make it possible to acquire models with additional degrees of freedom, leading to the possibility of reconstructing multidimensional variations of the potential states of cars and railway track.It is proposed to use an alternative concept of an information replica, as reflecting the adequacy of the form and content of three-dimensional dynamic models of various objects of railway stations.The possibility of developing a model info-replica to the level of a digital twin of the station is being studied in the formation of a software environment for modeling the physics of processes and reliable forecasting of the states of objects in the foreseeable event horizon with the production of dangerous states of infrastructure and rolling stock and a program-controlled return to the zone well, the regulatory technology of the station.The results obtained will make it possible to form a definite and stable point of view on the functional field of the possible use of the term “digital twin of a railway station”.
