In order to increase the efficiency of maintenance and availability of rolling stock, using the development of electronics, sensor technology and computer technology, on-board and stationary diagnostics are introduced. On-board systems are installed in a vehicle and used for continuous monitoring devices in use. Stationary diagnostic systems are used for a casual-periodic inspection of railway vehicles and these are installed directly on the track or very near track. Wayside detection system can achieve condition monitoring of vehicles in time of regular operation, without stopping. Using the collected information it is possible to analyze the condition of the equipment and to predict potential failures and errors that may occur in the future. This paper describes some of wayside detection system and points out that this approach can significantly improve the condition-based maintenance of railway vehicles.
