Abstract
Periodic rail and guide wear evaluation is essential for their reliability and safety. By regular measurement it is possible to determine whether certain rail or guide fragments need urgent replacement reducing the risk of accidents. In the paper at first we present the measurement system, which is intended to operate in small rail systems such as trams, light rail, narrow gauge rail, mine rail. It can be adopted to operate in two modes: manual pulled along the rail or guide or automatic attached to a measurement car. The measuring system is flexible enabling the measurement of different features of rail or guide geometry depending on the needs. By simplifying the design, the system can be operated by an unqualified personnel, however final wear evaluation has to be done by a qualified engineer. Finally we present the exemplary results of measurements performed on a selected rail section and the full data processing path. The method of relative calibration and synchronizing data from several measurement modules is also reported.
