Tramways in cities often ride in track curves of a small radius, which is followed by an increased effect of the vehicle on the track by the rail - wheel contact. Exactly with the aim to reduce these undesirable effects we designed a tram bogie with steered wheelsets. Moreower, for the vehicle passability trough strongly curved track inproovement, we proposed spcific, double treaded wheelset and coresponding track section. This invention is also registered under Patent Aplications Nr. a201701589 and Nr. a 201706685. A comparison of safety against derailment results for a tram vehicle running through a S-curve with considering of tread change is given in this paper. Three cases are compared: the first case is a T3 tram vehicle with original bogies, the other two cases represent a tram vehicle, which uses proposed inventions. Two ways of bogies placement under the vehicle body are investigated.

Keywords: double wheel tread, strongly curved track, derailment-safety, tramcar ride simulation analysis
