The topic of the digital twin (DTw) has been widely scrutinized lately. This article summarizes the main definitions of the DTw, highlights the differences between the known and used terms to assess and qualify its maturity levels, presents the existing gaps in the railway sector regarding the challenges for DTw implementation and uses in comparison with other industries. The main contribution of this paper is to present a holistic overview of the railway sector during the operation and maintenance phases, classifying the various use cases regarding the DTw of an existing railway infrastructure. For a selected use case, we will explain the necessary parameters to identify and characterize before architecture specification and development for the digital twin of an existing railway infrastructure.

摘要

The topic of the digital twin (DTw) has been widely scrutinized lately. This article summarizes the main definitions of the DTw, highlights the differences between the known and used terms to assess and qualify its maturity levels, presents the existing gaps in the railway sector regarding the challenges for DTw implementation and uses in comparison with other industries. The main contribution of this paper is to present a holistic overview of the railway sector during the operation and maintenance phases, classifying the various use cases regarding the DTw of an existing railway infrastructure. For a selected use case, we will explain the necessary parameters to identify and characterize before architecture specification and development for the digital twin of an existing railway infrastructure.
