Sažetak
In the course of supervision of tram track reconstruction in Zagreb and Osijek (Croatia) considerable damages caused by vehicle moving over the track running surface with irregularities were identified. The repair of such damages is expensive and necessarily requires the stopping of tram traffic. There is an interference with the road traffic on the sections shared both by tram and road vehicles as well, which is the case in the center of the city. The mentioned facts represent the major issue for the Zagreb tram track as the traffic loading of some sections in the center of the city is up to 15 MGT/year per cross section. Not only additional dynamic loads are generated by geometric irregularities on the track running surface but there is also the reduction of the element effects of tram fastening, the deterioration of the tram geometry, negative impact on vehicle, lowered comfort of journey and increase in the noise level. These consequences lead to the investigation of tram construction behaviour during the vehicle running along the track with a smooth running surface as well as along the tracks with irregularities.
