Diagnosing a railway track is a complicated task, both from the point of view of measuring equipment and organization. An important factor here is to ensure the safety of rail traffic while minimizing the cost of diagnostics (including time expenditures). One of the most promising is the approach based on the use of integrable track monitoring systems containing compact, relatively inexpensive sensors operating on different physical principles. This paper is dedicated to the peculiarities of the functioning, processing, presentation and transmission of information in organizing this approach, which is analyzed using the example of the InerTrack system developed with the participation of the authors.
