The classical mathematical models and the corresponding multibody programs are not always adapted to the increasing diversity of railway bogie design. New concepts in the design of bodies have a relatively poor scientific backround with respect to the know-how gained in the domain of conventional vehicle. The multibody program ROBOTRAN has been developed in that sense, offering the possibility to obtain the models of a family of railway vehicles - conventional or not - from a symbolic library of carbodies and bogies. The paper illustrate this through a comparison of behaviour between three bogies in the same situation: the entry curving at constant speed. Moreover, it is shown that a systematic segmentation of the railway models into carbodies and bogies sub-systems is a really powerful method to obtain various models from a family of potential tramway manufacturing projects. In this context, an original comparison has been proposed which aims at showing that, in case of tramway vehicles, the classical rigid wheelset is not really indispensable and that articulated bogie stuctures with independent wheels could be an interesting alternative in case of networks being composed of a lot of low-radius curves.
