An exact theory for the linear motion of a symmetrical railway vehicle placed on rotating rollers is given. Each axlebox can move in longitudinal, lateral and vertical directions with respect to the vehicle frame and the relative displacements are governed by undamped springs providing linear restoring forces. The displacements are supposed to be so small that the equations of motions can be linearised, so that the motion splits up into two mutually independent parts, viz. the symmetrical and the lateral motion. Dimensionless quantities are introduced in such a way that for the lateral motion, which is studied more in detail, the singular perturbation method can be used; the application of this method will be discussed in a forthcoming report. The theory is applied on the case of the ORE test bogie and on that of the 1:5 scale model of the Delft Laboratory of Engineering Mechanics. In the latter case a considerable discrepancy between the theoretical and the experimental results in found.
