A short review of electronically controlled pneumatic suspensions for railway application suggests that a better knowledge of the physics involved and how to control them could be of interest. The point of view adopted in this paper is to consider the air spring used in railway vehicle suspension as an autonomous actuator, including in a closed loop arrangement a height sensor, 2 solenoid valves - 1 for supply, 1 for exhaust - driven by differential pulse width modulation control (DPMW)), and electronic controller. Physical modelling of the actuator is developped here, as well as how to obtain a third order control model to be used as a basis for state feedback design. Linear controller is then simulation checked against non linearities as a 1/4 vehicle secondary suspension. At last, full vehicle non linear simulation with unbalanced lateral acceleration sensing and four air springs tilt control leads to conclusion about the global behaviour of the system in a realistic context.
