The bogie (10) comprises a frame (16), a set of wheels, and the pneumatic suspension for supporting a car body of a rail vehicle. The suspension includes a secondary suspension for vertically supporting a superstructure of the rail vehicle on the frame, the secondary suspension comprising at least one left secondary air spring (22L) and one right secondary air spring (22R) respectively located on a left and a right side of a median longitudinal vertical plane of the bogie. Left and right levelling valves (60L, 60R) independently connect each of the left and right secondary air springs (22L, 22R) to a pressure source (53) or to the atmosphere based on at least one height signal representative of a distance between a car body of the rail vehicle and one of the bogie frame and the set of wheels. Additional pneumatic means, e.g. a primary suspension or lateral actuators (18L, 18R; 118L, 118R) are provided for controlling relative motion between the frame and at least one of the superstructure and of the set of wheels. One or more control valves (58L, 58R) are used to connect the additional pneumatic means to the pressure source or to the atmosphere based on one or more pressure signals derived from the pressures of the left and/or right secondary air springs (22L, 22R).
