The invention relates to a controlled pneumatic tilting system in railway vehicles, with pneumatic springs (1.1, 1.2) for controlling the height of the body (4) with respect to the bogie (2), having opening and shut-off valves (7.1, 7.2) for said pneumatic springs, which incorporate a mechanical device formed by a rotating part (8.1, 8.2) and a seismic mass (9.1, 9.2), such that when the vehicle enters a curve said mechanical devices act on the valves which, due to the action of the pneumatic springs, makes the body (4) tilt in the direction opposite to the lateral acceleration.
