Abstract
This paper describes a research in geometry of grooved rails (type Ri 60/R10). The research was carried out in the last seven years (from 1994 to 2001). The measuring of rails geometry was done before building-in of the rails in to the tramway track or during the supervision grooved rails of production in the factory. Special attention was given to the width guide of grooved rails because the technical specifications for grooved rails (VDV OBERBAU Richtlinien) have not defined permitted tolerance for a guide width of grooved rails. Therefore, some difficulties arise from this fact, during production and supervision of grooved rails in the factory. The results of research can serve as a recommendation for the value of permitted tolerance of the guide width of grooved rails. The results can also be applied as a proposal in the setting of European Standard for grooved rails.
