Application of wheel sensor technology on railway network in Serbia


  • Present technologies applied on railway network in Serbia
  • Different technical solutions from suppliers of wheel sensor/axle counter equipment
  • Proposed modifications for application of these systems


The fast development of wheel sensor technology in the last decade has led to a series of technological innovations applied in the railway industry, especially in the area of railway signalling and rail vehicle engineering. On the railway network in Serbia these systems have been present since 2004, which is a sufficient period to issue a serious overview about the application of these systems. The presentation will give an overview of the present technologies applied on the railway network in Serbia, including a description of different technical solutions from suppliers of wheel sensors/axle counter equipment. The following aspects of these applications are reviewed: Track vacancy detection in stations/open line sections (axle counters), switching on/off of the level crossing interlocking devices and application of special systems for state detection of railway vehicles (hot box and hot wheel detection systems). Currently, new project documentation for these systems is under preparation, with technical solutions based on the principles of interoperability. This way, the railway infrastructure owner JSC Serbian Railway Infrastructure is trying to keep in line with the technological innovations from the respective field. The presentation also will present specific experiences of the railway infrastructure owner from both installation and maintenance phases, including some specific scenarios of application (e.g. performance of devices in case of extensive shunting/siding movements, influence of the railway vehicles with electromagnetic breaks, behaviour in the presence of water etc.), with further conclusions and recommendations from maintenance personnel and suppliers for future installation of these systems. Also, an overview of proposed modifications for application of these systems will be considered.
