Abstract
A rail vehicle having a car body, which is supported on a running gear by a spring device, and a rolling compensation device, which is coupled to the running gear and the car body. The rolling compensation device may be arranged kinematically in parallel to the spring device. The rolling compensation device counteracts rolling motions of the car body toward the outside of the curve about a rolling axis during travel in curves. The rolling compensation device, in order to increase the tilting comfort, is designed to impose, in a first frequency range and under a first transverse deflection of the car body, upon the car body, a first rolling angle about the rolling axis, which corresponds to a current curvature of a current section of track being travelled.
