The paper analyzes the results of the subsystem for continuous monitoring of vibration impacts on the railway catenary on the tension sections at the pilot facility of speed line St. Petersburg – Moscow. During the processing of diagnostic information more than 1 million diagnostic events have been considered. These statistics data allowed to systematize all diagnostic events and to establish some patterns for one or another emergency situations in the railway catenary, including the allocation of some typical pre-failure conditions and failures. The results of operation of the subsystem for continuous monitoring of vibration impacts on the railway catenary provide the insights into the best practices and the necessity of expanding the system’s functional capabilities for its further implementation and replication, which is quite important during the construction of speed and highspeed main railway lines.

Key words:
railway infrastructure; technical diagnostics; continuous monitoring; power supply; railway catenary; railway overhead catenary; vibration impacts; pre-failure condition
