Abstract
A multiple-unit railway vehicle having three car bodies where the respective neighboring car bodies are each connected in a pivoting manner to one another by means of a single coupling, and each car body sits only on one two-axle truck. In the vicinity of the respective center pivot and possibly also on the trucks, there are actuator elements that are used to influence the articulation angle between the longitudinal axes of the car bodies. To control the articulation angle so that when the train is traveling over a curved segment of track, the car bodies assume a position in relation to one another that corresponds at least to a significant extent to the static rest position of the railway vehicle on the corresponding section of track, the profile and curvature of the track are determined during travel for the segment of the track that currently lies between the first and last trucks, and from that measurement, the set point position is determined, and by means of the actuator system measurements are taken to counteract at least an overshooting or undershooting of the set point value.
