The aim of this paper is to familiarize readers with several telematic systems that may be observed on the Czech railway network. In order to function correctly, they use special technical devices for detecting positions of trains and their tracking. In the introductory part, a brief overview of individual ways of train detecting and tracking in the Czech Republic is given, which is then followed by a detailed description of the related telematic systems, including the principles of their functioning and graphic presentation of their practical use. The paper also contains demonstrative photo documentation and schematic illustrations of principles of functioning of the discussed systems.
