The measurements of an electromagnetic field emitted by a track-side CCTV cabinet were presented. Designs of this kind are operated in railway facilities; therefore, they should not disturb the functioning of other equipment, the rail traffic control systems, in particular (the so-called inner compatibility). An analysis of the obtained results facilitated developing a research model, and, further, improving its reliability and conducting an operational analysis, considering electromagnetic interference. This enabled us to determine a relationship allowing us to specify the probability of a track-side CCTV cabinet staying in a state of full ability. The presented discussions regarding a track-side CCTV cabinet, considering electromagnetic interference, allow us for the numerical assessment of different types of solutions (technical and organizational), which can be implemented in order to mitigate the impact of electromagnetic interference on the system functioning.

Implementation of high speed train sets changes the nature of dynamic interactions between rail and wheel. Therefore tests of railway turnouts have to be conducted again, re-analyzed what will lead to implementation of: - new standards for development and production of turnouts, - turnout transport and installation in blocks, - new structural solutions for critical turnout elements, - autonomous diagnostic systems, - implementation of data acquisition and analysis system, - turnout integration with drives, heating system and remote diagnostics. Scientific research conducted in cooperation with the suppliers of superstructure, railway signalling and IT products led to a new approach to the turnout as one system. In particularly remote diagnostics need innovative solutions from the area of IT using the Internet of Things, acquiring and processing of Big Data, learning algorithms and it will be even more important in the future. The paper emphasizes that in the case of a high speed railway turnout, it is necessary to resign from the classical model of system decomposition - breaking a system into subsystems like rail road, railway signaling and energy. Elements of all these subsystems are present in every turnout. E.g. for maintenance of each subsystem element, in the same turnout, in the classic approach, another person is responsible. This has got a large impact on the technical availability and operational parameters of the given turnout as a whole. It is postulated that the high speed railway turnout should be designed, tested, approved and operated as one integrated system. Only such an approach can ensure its high reliability, maintainability and safety.
