A bogie for a rail vehicle, comprising - a frame, - a set of wheels, - a pneumatic suspension comprising: - 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 and one right secondary air spring respectively located on a left and a right side of a median longitudinal vertical plane of the bogie, - levelling valve means (60L, 60R) connecting each of the left and right secondary air springs (22L, 22R) to a pressure source or to the atmosphere, - additional pneumatic means (18L, 18R; 118L, 118R) for controlling relative motion between the frame and at least one of the superstructure and of the set of wheels, characterised in that: - the levelling valve means (60L, 60R) independently connect each of the left and right secondary air springs (22L, 22R) to the pressure source 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, - the pneumatic suspension further comprises control valve means (58L, 58R) for connecting the additional pneumatic means selectively to a 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). - a frame, - a set of wheels, - a pneumatic suspension comprising: - 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 and one right secondary air spring respectively located on a left and a right side of a median longitudinal vertical plane of the bogie, - levelling valve means (60L, 60R) connecting each of the left and right secondary air springs (22L, 22R) to a pressure source or to the atmosphere, - additional pneumatic means (18L, 18R; 118L, 118R) for controlling relative motion between the frame and at least one of the superstructure and of the set of wheels, - 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 and one right secondary air spring respectively located on a left and a right side of a median longitudinal vertical plane of the bogie, - levelling valve means (60L, 60R) connecting each of the left and right secondary air springs (22L, 22R) to a pressure source or to the atmosphere, - additional pneumatic means (18L, 18R; 118L, 118R) for controlling relative motion between the frame and at least one of the superstructure and of the set of wheels, - the levelling valve means (60L, 60R) independently connect each of the left and right secondary air springs (22L, 22R) to the pressure source 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, - the pneumatic suspension further comprises control valve means (58L, 58R) for connecting the additional pneumatic means selectively to a 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).
