Applications, RFID equipment is used to identify an ID-tag which is fixed to the train or wagon in order to know when it is passing a particular position. The reader is positioned at the side of the track or between the rails on the sleeper. Typical applications include providing track side systems with the location of each carriage or wagon as it passes the reader. These systems include track-side systems for passenger information, condition monitoring and track-n-trace fleet management systems. Location systems are applicable to all types of transportation and for freight and passenger systems.

The sensors are mounted under the rail and need no decommissioning of the track. As a result of using fibre
optical technology there is no electrical connection to the rail and the system is insensitive to electro-magnetic interference. The identification part of the system, provided by the system, consists of a heavy-duty ID-tag, which is easily mounted on the wagon-side. The readers are easily installed at the side of the track.

As wheel defects are identified at an early stage, less trains need to be taken out for regular service. Trains in operation hold a higher quality level, avoiding service problems due to wheel
or axle quality problems. This leads to improved passenger convenience such as reduced noise and vibration levels
