Trams have very important part in Belgrade public transportation system. However, because of unfavorably tram ageing structure, poor condition of rails as well as complete rail infrastructure and maintenance system that requires meaningful improvement, Belgrade trams are in very unsatisfactory shape which disables fulfillment of transport requirements even today and especially in the future. Because of all above said it was important to analyze possibilities for renewal and modernization through serious feasibility study. This paper shows results of the existing Belgrade tram rolling stock condition analysis. Special attention was given to the reliability and availability of tram rolling stock as a foundation for defining technical level of the potential modernization as well as technical and exploitation characteristics of new tram cars that could be purchased in the next period.
